What do mirrored sunglasses do? | Is mirrored better than polarised? | How to clean mirrored sunglasses | Where to buy mirrored sunglasses | Conclusion

Mirrored glasses shield your eyes, guarantee privacy, give you clear vision and, to top it all off, they look great!
What are Mirrored Sunglasses

If you are an adventure-seeker looking for a pair of sunglasses to make an effortless fashion statement without sacrificing functionality, mirrored sunglasses are the perfect choice for you! So, what are mirrored sunglasses?

Mirrored sunglasses, also known as reflective sunglasses, are one of the most popular styles of sunglasses on the market. They come in diverse colours and styles and are made with durable lenses with a reflective coating on the outside, giving them a mirrored look with major functional benefits.

What do mirrored sunglasses do?

What are Mirrored Sunglasses

When wearing mirrored sunglasses, you will not only look fashion-forward, but you will also experience the many benefits that the style offers, including:

1. Protection against UV Light –  Too much direct UV light on your eyes can cause damage, so it is important to protect your eyes as much as possible. Mirrored sunglasses offer great protection because the reflective surface on mirrored lenses has 10-60% higher sunlight reflection compared to normal tinted variations and can often be found with 100% UV protection. 

2. Reduced Glare – The glare from the sun can cause headaches for those with sensitive eyes, and for those doing water and snow sports, the glare can make performance much more difficult. Luckily, reflective sunglasses can reduce glares for a more comfortable outdoor experience, making the style a go-to for many athletes. They are also often used for snow goggles!

3. Brighter field of vision – Since mirrored sunglasses reflect light rather than absorb it, they offer brighter vision when wearing them. If you spend a lot of time in the sun, this benefit is great because it will ensure less strain on your eyes throughout the day.

4. Durability – The mirrored coating on the lenses is one of the most durable coatings available. Many brands also include a scratch-resistant layer, which protects against the wear and tear of everyday life. If you are looking for extra protection, be sure to check that this option is available before purchasing.

5. Anonymity – Say goodbye to awkward eye contact! While mirrored lenses can certainly make you stand out in the crowd, they can also significantly increase your privacy. The reflective lenses will hide your eyes, so you can go about your day feeling a bit more under the radar. 

6. Style – Mirrored sunglasses are also extremely stylish! With colours ranging from silver, pink, blue, green, gold, and more, there are limitless options to fit any personality. Brands such as Ray-Ban, Oakley and Carrera offer an endless number of colour and frame combinations for an instant boost in confidence and style.

DID YOU KNOW

Mirrored sunglasses are sometimes called “cop shades”. This stems from their popularity among US police officers.

Is mirrored better than polarised?

Mirrored and polarised sunglasses have many similar benefits as well as some differences, and the preference of one over the other totally depends on what you are looking for. Both offer great UV protection, reduce glare, and are suitable for spending excessive amounts of time in bright conditions. 

The most notable difference is that mirrored lenses are usually less costly and offer a more extensive array of lens colours. While polarised sunglasses often have grey, green, and amber tints, mirrored choices come in bright and bold colours. 

However, before you choose, you can discover the many benefits of polarised lenses to compare them and determine the best choice for you! If you are still undecided, you can combine both options for a polarised, mirrored pair of sunglasses.

How to clean mirrored sunglasses

As with all sunglasses, it is important to clean them thoroughly to ensure they last as long as possible. Mirrored lenses can appear smudged more easily than normal tinted lenses, so you should clean them often. 

While there are many methods online that explain how to remove scratches from sunglasses, we do not recommend trying this because it can ruin your lenses. Instead, it is best to get replacement lenses so your sunglasses last.

Where to buy mirrored sunglasses

Ready to try out a pair of mirrored sunglasses? At SmartBuyGlasses, we offer a vast selection of sunglasses with mirrored lenses. You are sure to find a pair that best suits you among our options from over 180 designer brands that feature bold colours, diverse frames, and unbeatable customer service.

Use our Virtual Try-On technology to make your purchase with 100% confidence. Try on an endless number of styles from the comfort of your own home. Once you choose, you can make the purchase and relax knowing we have a 100-day return policy, free shipping, and the best price guarantee.

Conclusion

Whether you are walking through the city streets, making waves during water sports, or feeling adventurous to try a new outdoor activity, mirrored sunglasses are the perfect choice to ensure style and success for any occasion.

When buying a new pair of sunglasses and choosing the colour of your lenses, remember that different lens colours have different purposes.

Depending on weather conditions or the activities that are part of your daily routine, the colour of your lenses can enhance the overall performance of your glasses. Most people choose lens colours based on aesthetics, but did you know that different lens colours serve different purposes? 

In this article, we will guide you through the different colour options, explain the difference between each lens colour and help you understand how to choose the best one to suit your needs.

Does the colour of sunglass lens matter?

Yes, colour has a noticeable effect on the sunglasses. Depending on your lifestyle, lens colour also affects your eye health during certain activities. This makes it essential for you to find a suitable lens compatible with your daily activities and needs.

What about mirrored lenses?

Mirrored sunglasses are the perfect stylish option to protect your eyes against UV rays. The fully reflective coating used for the lenses gives the mirrored look everyone loves these days. Combined with polarised lenses, they offer maximum protection against UV rays and increase clarity. Both polarised and mirrored lenses, either separate or combined, come in different colours. Below, we will be listing the most popular colours and what is the advantage of choosing each lens colour.

Lens colour guide

Grey and black lenses are the best option if you’re looking for a neutral lens tint. These lenses are perfect for all weather conditions and are the top choice if you want to perceive colours in their purest form, even when wearing sunglasses.

Grey lenses are great at reducing the brightest glare and are perfect for outdoor activities and sports such as surfing, cycling, golfing and driving. If you’re looking for the everyday use type of tint, this is the one.

Amber and brown tints are extremely popular as they provide excellent depth perception. These lenses have a warm, reddish tone and are perfect for reducing glare, enhancing contrast, and helping maintain visual acuity. Amber and brown lens sunglasses are perfect for sunny days and outdoor activities such as fishing, shooting, tennis, or baseball.

Green Lenses are one of the trendiest when it comes to polarized or mirrored sunglasses. They are perfect for sunny days but also in low light conditions. Whether sunny, cloudy, or anything in between, green lenses will work amazingly well, giving you excellent vision and reducing glare.

Green lens sunglasses are one of the most popular ones for outdoor activities: no matter what sport you have on your agenda, these lenses will increase contrast and visual sharpness and enhance shadow.

Yellow lenses are more efficient in low-light environments like cloudy or rainy days. One of the benefits of using yellow lenses is that when playing sports, these lenses are great for focusing on moving objects. Another advantage is that when navigating, they are perfect in hazy or low-light conditions. Yellow lenses are also very popular amongst gamers as they filter blue light from computer screens and other screen devices.

Blue lenses are not only very trendy but also well-known for enhancing clarity and defining contours. These lenses improve colour perception and do wonders in low-light conditions. They’re suited well for all water sports, snow sports, and golf. 

Red and pink tints increase contrast by blocking blue light and enhancing depth perception. They are also soothing for the eyes and more comfortable than others for longer wear times. Pink and red lenses perform their best on extremely sunny days and snowy conditions.

DID YOU KNOW?

Black lenses are perfect if you’re looking for a neutral lens tint while brown lenses provide excellent depth perception. Blue lenses are suited for all water sports. For rainy days, yellow lenses are a must!

Contact lenses are becoming more advanced and available for those in need of vision correction for nearsightedness, farsightedness or astigmatism.
Contact lenses

Contact lenses have become much more comfortable, breathable and versatile since they were first designed in the 19th century. 

The earliest versions were blown from glass, so it’s no wonder they were less popular than they are now. Today, contact lenses are thin, plastic lenses used for vision correction. 

Contact lenses differ from glasses as they are worn directly on the cornea, the front surface of the eye. Contact lenses adhere to the shape of the eye, allowing a wider field of vision and fewer distortions or obstacles than prescription glasses. 

Are glasses prescriptions and contact lens prescriptions the same?

The lens power in glasses and contact lenses can correct nearsightedness, farsightedness, or astigmatism. Just as contact lenses and glasses are not worn in the same way, their prescriptions also differ. 

Glasses generally rest about 12 mm from the eyes, whereas contacts are worn directly on the eyes and have a much smaller surface area. The distance from the eye directly impacts the difference in lens power.

A prescription for eyeglasses and contact lenses will require separate eye exams and measurements from your optometrist as the prescriptions will differ. 

Additionally, with so many types of contact lenses available it is important a correct fit and brand is prescribed. 

Ordering contact lenses with the wrong prescription can lead to symptoms such as blurry vision, headaches, eye strain or fatigue and eye pain (AAO, 2012).

How to read a contact prescription

If you’ve received an eye exam, got your new prescription and are ready to buy contact lenses online but need clarification, you’re not alone! 

Codes like “D, CYL and AXIS” are all over your prescription, but what do they mean?

Many people need different levels of vision correction in each eye, so a contact lens prescription may have two sets of numbers—one for your right eye and one for your left eye. 

OD, oculus dexter, refers to your right eye, while OS, oculus sinister, refers to your left eye.

  • Base Curve (BC) determines the type of fit required for the lens to meet the curve of your eye. It is measured in millimeters (mm) and aligns with the curvature of your eye.
  • Power (PWR)/Sphere (SPH) refers to the strength of your prescription. You will see a plus sign (+) or a minus sign (-) followed by a number. If you are farsighted, your figure will begin with a plus sign. If you are nearsighted, it will start with a minus sign.
  • Diameter (DIA) is the entire width of your contact lenses. Also measured in millimeters, the higher the base curve, the flatter the cornea’s curvature.

If you need astigmatism correction, you will have two additional terms and numbers on the prescription. For those with astigmatism, you will need toric lenses.

  • Cylinder (CYL) represents the severity of your astigmatism and the additional visual requirements needed for vision correction.
  • Axis (AX) is measured in degrees and tells you where and how your astigmatism is located and oriented on your eye. 

For those with presbyopia or who need multifocal lenses, you will notice one or both of the following on your prescription.

  • Addition (ADD) determines the amount of correction you need to be able to see clearly at a close distance.
  • Dominant (D/N) identifies your dominant (D) and non-dominant (N) eye. The dominant eye usually prioritises distance vision, while the non-dominant eye prioritises near vision.

Your prescription will also include a brand of contact lenses. Contact lens boxes will include most of the prescription details on them as well. 

Different contact lens brands have distinct features and measurements, so it is important only to order the brand prescribed. If you want or need to switch brands, it is essential to let your eye doctor know.

What do the numbers mean in a contact prescription?

If you understand what the codes mean, you may still wonder what the numbers mean. BC and DIA will not be present on your glasses prescription, as they refer only to a contact lens prescription. 

Measured in millimetres, the BC is always a number between 8 and 9 and will align with the curvature of your eye. DIA is typically between 14 and 14.5 millimetres and determines the entire width of your contact lens.

The PWR or SPH (prescription strength) is measured in increments of 0.25 diopters. The further from zero, the stronger the vision correction needed. A negative number, -1.00, indicates nearsightedness. 

A positive number, for example, +2.00, indicates farsightedness.

CYL is always a negative number measured in increments of 0.25, showing the amount of astigmatism. AX is a number between 0 and 180 degrees, referring to the angle of correction needed. 

For those with presbyopia, the ADD figure is a positive number between 0.50 and 3.00.

If you still need help reading and understanding your contact lens prescription, contact your optometrist or head to our Optical Centre to speak with one of our opticians.

How long is a contact prescription good for?

Most contact lens prescriptions expire within one to two years of your last eye exam. Once your prescription has expired, it is important to see your eye doctor for a new contact lens prescription. 

Wearing the wrong prescription contacts may create discomfort and lead to further vision problems.

How low do contact prescriptions go?

Contact lenses are becoming more and more diverse and available for those in need of vision correction. Contact lenses are now offered at the lowest prescription of -0.25/+0.25. 

Many people neglect to wear their low-prescription eyeglasses because of inconvenience, but wearing low-prescription contacts might be a good solution as they can be considered less obstructive.

Contact lenses don’t interfere with equipment such as helmets, hats, or goggles. During sports or exercise, contact lenses don’t get in the way. 

They’re not at risk of falling off or breaking. Contact lenses are not usually affected by weather as they don’t fog up in the cold.

Correcting your vision and protecting your eyes at any prescription level is important. If you’re avoiding your glasses for ease and convenience, speak with your eye doctor about receiving an eye exam and switching to contact lenses.

What is the strongest contact lens prescription?

Advances in contact lens technology have made it so that contact lenses can be worn safely and comfortably by those with high-power prescriptions. 

Standard contact lenses are readily available in prescriptions from -12.00 to +8.00, and cylinder powers up to -2.25 or -2.75 for astigmatism correction. 

Extended-range lenses are also available with spherical powers of +15.00D to –20.00D and up to –5.75D in cylindrical powers (Contact Lens Spectrum, 2016).

Soft contact lenses with high powers have thicker edges compared to low-powered ones. These thicker edges may be less comfortable to wear and cause more dry eyes.

 Many people with high-power prescriptions choose RGP lenses (rigid gas permeable or ‘hard’) as they are smaller and thinner than a soft lens. 

RGP lenses don’t bend like soft lenses, but they let oxygen through so your eyes can breathe.

Advantages of contact lenses

While contact lenses might not be for everyone, many contact lens wearers won’t go back to standard eyeglasses. Contacts conform to your eye, reducing distortion and obstructions. 

They won’t stop you from playing sports or competing in outdoor activities. Contact lenses are also available in coloured lenses, so you can experiment with your eye colour.

With varying contact lens power, affordable contact lenses and varying lens materials, there are contact lenses for everyone. 

Based on your lifestyle, you can speak with your eye doctor about purchasing daily disposable lenses, weekly or monthly lenses.

Contact lenses prescription

Buying contact lenses doesn’t have to be confusing. They’re an excellent alternative for those looking to ditch their eyeglasses. It is important to remember that glasses and contact lens prescriptions are different.

Do not assume that any numbers on your glasses prescription will match your contact lens prescription. 

If you want to try contact lenses, schedule an eye exam to determine what you need and what lens type will best suit you. 

For people with vision problems, contacts are an effective, almost invisible tool. The thin lenses correct vision problems including nearsightedness, farsightedness and astigmatism. 

You can even wear contacts if you have presbyopia and need bifocals. As technology and medicine continue to advance, contact lenses are only improving. 

Speak with your eye doctor about getting a prescription for contact lenses and start seeing clearer and more comfortably.

Prescription sunglasses combine prescription lenses with sun protection. Order them online in just 4 easy steps!

Are you constantly straining your eyes to see while wearing non-prescription sunglasses outside? If you wear prescription glasses every day, it’s time to invest in a pair of prescription sunglasses to wear outdoors.

Prescription shades will give you the best of both worlds: clear vision and protected eyes. Indeed, in addition to protecting your eyes from the sun’s UV rays, prescription sunglasses will help you see, reduce eye strain and help avoid squinting.

Continue reading to learn more about what rx sunglasses are, their benefits, how to add your prescription online and how to choose the best pair.

People who need prescription lenses sometimes still wear non-prescription sunglasses. Doing so can result in eye strain, headache and frustration from being unable to see clearly in the sun.

These irritating symptoms are far from ideal when combined with the sun, sea, sand and sunscreen. 

With prescription lens sunglasses, you can sunbathe, hike and easily play outdoor sports. Sunglasses are available with prescriptions for nearsightedness, farsightedness or astigmatism. You can also get sunglasses with progressive lenses.

Are prescription sunglasses worth it?

Your everyday lifestyle in the sun will transform once you invest in prescription sunglasses. Here is why:

  • They provide clear and protected vision on sunny days
  • They ensure you are not straining your eyes outside to avoid future eye issues
  • No need to carry around two pairs of glasses wherever you go
  • More comfortable than wearing contact lenses and sunglasses

How to order prescription sunglasses online

How to order prescription sunglasses online

We recommend booking an appointment with your eye care provider for an up-to-date prescription before ordering your prescription lens sunglasses. 

However, if you have your current prescription details but they’re misplaced, try our Prescription Lens Scanner app to reveal them in minutes. 

Unlike contact lenses, your prescription will not differ for your eyeglasses and sunglasses. Once you have your prescription, you must follow these steps at SmartBuyGlasses:

At the customisation stage, you can tailor the sunglasses lenses with options such as anti-reflective lenses that are UV400 protected. You can also choose popular mirrored prescription sunglasses or polarisation lenses for your sunglasses. For more information, see the section ‘how to choose your prescription sunglasses’ later in this article.

How much do prescription sunglasses cost?

Sunglasses with a prescription cost a bit more than non-prescription sunglasses since your specific prescription needs to be built into the lenses. 

However, in-store prescription lens sunglasses are often more expensive than buying them online.

How to choose prescription sunglasses

Firstly, choose the frame model you like. Read our short guide for some tips to determine what frame shape will suit you. You can also use our revolutionary Virtual Try-On tool to wear your chosen frames digitally before you buy!

Sunglasses with prescription lenses can be made with various materials, including high-index lenses, polycarbonate lenses, CR-39 plastic lenses, trivex lenses and even glass lenses. When selecting prescription lenses for your sunnies, there are several types of lenses to consider.

DID YOU KNOW?
Prescription sunglasses are the perfect solution to combine perfect vision and protected eyes. Shopping online for a pair it's easy and convenient, and you can customize them with different types of lenses.

Photochromic prescription lenses

A photochromic tint will give your lenses a transition effect – which means they will automatically adjust to changes in ambient light conditions. This means they darken in the sun and become clearer indoors, which is ideal if you do not want to carry multiple pairs of glasses.

Polarised prescription sunglasses

Polarised sunglasses greatly eliminate glare to improve visual comfort and reduce eye fatigue. This lens is ideal if you spend time near water, snow, driving and playing outdoor sports.  

Colour-matching Lenses

By choosing this option, our manufacturers will match your prescription lenses to the same colour as the original sunglasses’ lenses. These lenses will still offer you UV protection and ensure you look trendy!

Mirrored prescription sunglasses

Opting for mirrored prescription sunglasses is ideal for fashion-conscious wearers. The lenses have a mirrored coating that helps to reflect light away from your eyes more than any regular tinted sunglasses.

We recommend contacting your optician to ensure you have the correct and updated prescription before you start shopping. Plus, if you still have some questions about prescription sunglasses, you can talk with one of the certified online opticians at SmartBuyGlasses.

Opting for mirrored prescription sunglasses is ideal for fashion-conscious wearers. The lenses have a mirrored coating that helps to reflect light away from your eyes more than any regular tinted sunglasses.

We recommend contacting your optician to ensure you have the correct and updated prescription before you start shopping. Plus, if you still have some questions about prescription sunglasses, you can talk with one of the certified online opticians at SmartBuyGlasses.

SUMMARY

Plano lenses are eyeglasses lenses that don’t offer any vision correction.

They are generally used for aesthetic, safety and eye health reasons.

Glasses have many benefits, even if you have perfect vision. In this article, we will explain plano lenses, demo lenses, and the difference between plano lenses and prescription lenses. 

Discover why plano lenses are great for the workplace, sports, or to provide a realistic aesthetic to your look!

What are Plano lenses?

Not all glasses require corrective lenses, and when this occurs, glasses can be fitted with two types of non-prescription lenses: demo or plano lenses. 

Furthermore, plano lenses are optical lenses that do not have any value power. Therefore, they do not help correct your vision. 

In the eyewear industry, plano-convex lenses are described as flat and do not refract or focus light through the lens. 

So if you have blurry vision, see double or can’t read the words right in front of you, then plano glasses are not going to help.

We recommend that you have an eye test to find out if you do not require any prescription to correct your vision. 

For example, you may need a prescription from your eye doctor to correct astigmatism to improve distance vision (progressive lenses) or you may even need a prescription suitable for reading glasses. 

If you notice any changes in vision or have not had an eye test with your doctor in two years, we recommend booking an appointment.

What does Plano mean on eye prescription?

The word plano is Latin for ‘flat’, and if this is found in the SPH section of your prescription, it means you do not require nearsighted or farsighted correction. 

You will know if you require plano lenses if your eye prescription refers to ‘plano’, ‘PL’ or ‘0.00’, found under the sphere box (SPH) measurement section.

DID YOU KNOW?

If 0.00 is written on your eyeglass prescription, this is equivalent to plano. This indicates that there is no refractive power and no corrective power is needed. Therefore, you do not have any distance problems with your sight, astigmatism or anything to be corrected.

What are demo lenses?

Another type of non-prescription is demo lenses, and they are mainly used for demonstration purposes, such as for glasses displays in retail stores. 

Demo lenses can help you understand what prescription glasses or sunglasses look like before you purchase them.

Plano vs demo lenses

Plano and demo lenses are not the same and should not be confused. Plano lenses are often made from CR39 lens material and are thicker than demo lenses. 

In addition to this, extra protective lens coatings can be added to a plano lens that can’t be added to demo lenses, like the following:

  • Anti-scratch coating
  • Blue light filter
  • Tinted lens coatings

Demo lenses are thinner, do not have any additional lens coatings, and sometimes also have printed brand labels on the lens. They are like a simulation of what the glasses can look like.

What are Plano lenses used for?

The various reasons why you’d want or need to wear plano glasses are:

  1. Aesthetic reasons: If you’re looking to change up your look, make a fashion statement, or add the finishing touch to your outfit, you might opt for plano lenses. They can be helpful in boosting a look or helping to frame an outfit without any vision correction.
  2. Safety reasons: In many workplaces, companies have to follow protective eyewear regulations to help prevent eye-related injuries. Safety glasses can help protect from hazardous elements such as chemicals. During the working day, you can also protect your eyes from glare or blue light emitted from digital devices with blue light glasses. Once you have chosen a pair of glasses you like, you can add blue light to them.
  3. Eye health issues: If you are blind in one eye or suffer from eye health issues, you may benefit from protecting your eyes with plano lenses.

Do you need Plano lenses?

If you are looking for eyewear for any of the reasons mentioned previously, then you may need plano glasses. 

You can wear any style of glasses or sunglasses with plano lenses and benefit from protective lens filters, such as UV protection. Plano lenses in glasses can also serve as protective eyewear, whether or not you need vision correction or prescription lenses.

You can even find plano contact lenses. So what does plano mean in contact lenses? Plano contact lenses are the same as plano in glasses; they do not help correct visual impairments. 

Usually, plano-coloured contact lenses fall into this category of non-prescription contacts that people wear mostly for cosmetic purposes.

Wear Plano glasses

Don’t need prescription glasses but still want to benefit from the trends, styles and protective lens coatings that eyeglasses and sunglasses provide? Plano lenses are what you are looking for.

Eyewear with plano lenses does not have any power values for vision correction and can also be used as PPE (personal protective eyewear). 

Whether you need to protect your eyes at work, on holiday or simply want to look fashionable, you can try to wear plano lenses. 

You can find a variety of eyewear with quality protective filters to help correct vision or improve your look with SmartBuyGlasses.

We recommend visiting your local optometrist for an up-to-date prescription to ensure you do not require single-vision lenses or progressive lenses with corrective power. If you need some quick advice, contact our online optician!

Photochromic and polarised lenses each have their respective qualities. Find out which type is the best choice for you.
woman wearing transitions glasses

Sunglasses are a versatile accessory; they protect your eyes and make you look cool. You may put a lot of thought into the frame of your glasses or sunglasses, but choosing the right lenses is just as important.

With so many lenses available, it may be difficult to understand which are right for you. The best lenses for an individual will depend on your unique visual needs and what you hope to get from your shades.

Polarised and photochromic lenses are two of the many lens choices which offer excellent UV protection, but many wonder, what exactly is the difference?

What is the difference between photochromic and polarised lenses?

Photochromic and polarised lenses both effectively protect your eyes from harmful UV rays. They’re both available in a diverse range of frame styles and are highly beneficial to wearers. The difference?

Simply put, photochromic lenses automatically adjust from clear to dark with UV exposure. Photochromic lenses start clear and darken upon coming into contact with UV light. 

Unlike photochromic lenses, polarised lenses are always tinted and have a special coating that filters out horizontal light rays, which essentially means they cut out glare.

DID YOU KNOW?

Polarised lenses were invented in 1936, exactly thirty years before photochromic lenses.

What are photochromic lenses?

You may have also heard photochromic lenses being referred to as Transitions® lenses, but are they the same?

Transitions® lenses and photochromic lenses work the same way and are essentially the same thing. Transitions® is a brand name and type of photochromic lens manufactured by Transitions Optical Limited.

Photochromic lenses are an excellent choice for people who are sick of switching between their prescription glasses and prescription sunglasses.

As light conditions change, so do the lenses, depending on the intensity of ultraviolet light. And the best part, you never have to change your frames.

Inside, away from UV light, photochromic lenses are clear, but as soon as you step outside and UV rays are present, they gradually darken.

Plastic photochromic lenses and glass photochromic lenses use the same technology but are a bit different in their composition. 

Plastic photochromic lenses include molecules of silver halide that are usually layered or embedded evenly onto the surface of the lens, providing an even tint when exposed to UV light conditions, whereas glass photochromic lenses contain the molecules within the glass.

The convenient all-in-one nature of these lenses provides extra comfort in changing environments for those who need prescription eyewear.

How do photochromic lenses work?

It’s all about a chemical reaction. Photochromic lenses have light-sensitive molecules that shift their structure when combined with UV light, allowing them to easily adapt to changing light conditions. 

When this light is absorbed, the lenses darken. Away from the sunlight, the process reverses, and the lenses become clear again.

gif showing photochromic glasses

On average, photochromic lenses darken in 30–60 seconds and clear a bit slower in 2–3 minutes.

The molecules in photochromic lenses are not only sensitive to the presence of UV light but also the amount of it. When exposed to bright light, they will change more quickly; less light and they’ll change more slowly.

If you find yourself in the shade, you might notice your lenses darkening less than in direct sunlight. UV light is still present in low light settings like overcast skies, causing photochromic lenses to darken even in these conditions. 

Pros and cons of photochromic lenses

The biggest advantages are how cost-effective, convenient and versatile photochromic lenses can be. With no need for a separate pair, one pair of glasses acts as both your eyeglasses and sunglasses.

Photochromic glasses mean no need to worry about changing your glasses upon entering or exiting a building or the sunshine. 

The versatility of photochromic lenses is especially beneficial when the weather changes throughout the day, making them great for those with an active lifestyle. 

If you’re on the slopes, or hiking in the woods, and the sun keeps disappearing behind the clouds and coming out again, your vision and comfort remain unaffected.  

While photochromic glasses benefit many wearers, there are some disadvantages to consider. Temperature impacts the rate at which photochromic lenses darken or clear up. 

The lenses usually darken more fully in cold weather but take longer to clear. In warmer weather, they may not darken as much but will become clear quicker.

Most photochromic lenses perform well for three-plus years, but eventually, they will become less reactive to light conditions and take longer to shift between clear and tinted. 

Some models, including the Transitions XTRActive® lenses, have more photochromic molecules allowing them to transition even while in the car. These lenses always have a very light base tint and will not go as dark in the car as they do outdoors.

What are polarised lenses?

Polarised lenses are tinted lenses with a special coating that blocks glare, boosts visibility, increases clarity and enhances contrast to make your surroundings more vibrant.

difference between polarized vs non polarized glasses

Polarised sunglasses provide optimal vision for outdoor activities, as they block out reflections that come from smooth surfaces, like, snow or water.

When the sun reflects off these surfaces, it causes a powerful, horizontal glare that may cause eye damage and strain.

Polarised lenses improve visual clarity by reducing glare from reflective surfaces, making it easy for your eyes to focus, while also increasing colour contrast and giving you greater depth perception.

How do polarised lenses work?

Whether hiking, cycling or boating, polarised sunglasses are a great option for those who spend a lot of time outdoors. The lenses are designed to reduce glare and enhance outdoor vision, helping improve performance while making colours look more vibrant.

Polarised lenses are well suited for driving during the day, as glare from other cars, or the road, is a common scenario. 

With reduced glare comes a lower risk of eye strain. Polarised lenses are an excellent solution for people with light sensitivity, and they may even be recommended to patients who have had cataract surgery.

With reduced glare comes a lower risk of eye strain. Polarised lenses are an excellent solution for people with light sensitivity, and they may even be recommended to patients who have had cataract surgery.

With many advantages, there are some things to consider before buying polarised lenses. Polarised lenses may reduce vision clarity when looking at LCD screens or certain displays. 

For anyone working in a job where looking at display screens is expected, you should test polarised lenses on them before purchasing. 

While polarised lenses are beneficial in snowy conditions, they may make it harder to see patches of ice.

If you’re skiing, snowboarding, driving or walking where there might be lots of ice, it may be best to avoid your polarised sunglasses and reach for another pair.

Another disadvantage is that polarised lenses are always tinted, so if you wear prescription glasses, you will need to carry around both your glasses and sunglasses. 

Which is better - photochromic or polarised lenses?

Polarised and photochromic lenses have distinct qualities and advantages, making them great options for your collection. Generally, neither is considered better than the other.

Photochromic lenses are a great option for those who are always on the run, with one pair of glasses serving as eyeglasses and sunglasses.

Polarised lenses block out glare and reflections, not only improving vision but providing a level of safety, and are a great choice for outdoor activities.

Both types of lenses will protect your eyes from the sun’s harmful UV rays. The best choice is always individual, so it’s best to review the functionalities of each, consider your environment and budget and compare this to your lifestyle.

Depending on what you use your sunglasses for, one may be a better choice than the other. 

If a reduction in glare will benefit your performance in fishing or cycling, for example, you may choose polarised lenses. Photochromic lenses may be best for you if you need a pair of sunglasses for everyday wear.

Lenses don’t have to be complicated; consider the differences and your vision needs, so you can buy and wear what works for you. With so many options, it’s always best to be informed about your choices. 

Head to our Optical Centre to learn more about these lenses, or speak with one of our opticians. And remember, whether you purchase photochromic or polarised lenses, make sure they fit into frames that make you feel confident.

Is There a Difference Between Contact Lens and Glasses Prescription?

contact lens and prescription glasses

If your vision needs correction, you may be prescribed a glasses prescription or contact lens prescription. Both help improve your vision, but are glasses prescriptions and contact lens prescriptions the same? 

A common query is if it’s possible to convert a glasses prescription to a contact lens prescription. Read on to discover the answer to these intriguing questions regarding your prescription.

Are glasses prescriptions and contact lens prescriptions the same?

Even though the prescription for glasses vs contact lens prescription may look similar, they are quite different. 

Since prescription glasses rest slightly in front of your eyes, around 12 millimetres away, and contact lenses sit directly on them, you need two separate tests to determine their unique measurements. 

This means that the parameters specified on your glasses prescription may often differ from your contact lens prescription.

Can you convert a glasses prescription to a contact lens prescription?

No, it is impossible to convert a glasses prescription to a contact lens prescription directly. Furthermore, you cannot convert a contact lens prescription to a glasses prescription. 

Doctors can prescribe your contact lens prescription after you have completed a contact lens exam.

Can I use my glasses prescription for contact lenses?

As well as not being able to convert your prescriptions, you cannot use your glasses prescription to work out your contact lens prescription. 

It is important to note that only some people who wear glasses can also wear contact lenses. Therefore, it is recommended you get an eye test for both prescriptions. 

Are contact lenses or glasses better?

When choosing between contact lenses or glasses, we recommend you consider your lifestyle, comfort and price. 

For example, eyeglasses require little cleaning and maintenance, as well as not having to physically touch your eyes, helping to avoid the risk of eye infections. 

However, contact lenses do not fog up, which is useful when playing sports, but they can be more expensive than glasses. We recommend trying glasses and contact lenses to see which suits your lifestyle better.

Where to buy contact lenses and glasses online

You can find affordable glasses or contact lenses online or in-store at your local opticians as long as you have an up-to-date prescription. 

You can use our free Lens Scanner app to reveal your current glasses prescription in minutes. However, if you haven’t had an eye exam in the last two years, we recommend booking an appointment to ensure your prescription is accurate. 

You will need a separate eye test to determine your contact lens prescription, but often you can get your contact lens exam performed at the same time as your eye exam.

So, whether you prefer to wear contact lenses or glasses, you need to book an up-to-date eye exam to ensure your eyes are healthy. 

Furthermore, remember that you cannot use the same prescription for your glasses and contact lenses and require two separate tests.

It’s no secret that low light conditions make night driving more difficult, but can blue light glasses help to improve visibility at night?
man driving a car wearing driving glasses

Blue light glasses have become quite popular for those who use technology daily, which is likely most of us as we are living in a multi-screen era.

They help filter out the harmful blue light rays emitted from digital screens, offering protection from their negative effects

While we understand how they work to protect against screens and minimise blue light exposure, we have begun to question the other benefits of blue light glasses beyond the digital screen.

Driving at night can sometimes be stressful, with low levels of natural light combined with glare from high powered LED headlights.

It may be even more difficult for people who wear prescription glasses or suffer from vision issues – it’s no wonder why some people tend to stay off the road at night. 

With increased exposure to blue light on the road with LED headlights and street lamps, what if the blue light glasses we reach for at our computer screens could also help us drive at night?

What are blue light glasses?

Blue light-blocking glasses are exactly what they sound like; they’re glasses that have special lenses with a blue light filter that help with preventing blue light coming from digital screens from passing through the lens.

This reduction in exposure to blue light allows us to concentrate further reducing eye fatigue or digital eye strain.

Blue light is a part of the visible light spectrum that produces short and high-energy waves, and can be seen by the human eye.

Although our eyes can see blue light, they cannot effectively filter it, allowing more light to pass through. 

Some blue light filters result in slightly yellow tinted lenses, which block the harmful blue light rays from passing through the lens and into the eye. 

infographic showing how blue light filtering lens works

Blue light blocking glasses have become quite popular among those who use technology daily, which is most of us.

Blue light blocking lenses help filter the harmful artificial blue light rays emitted from digital screens and digital devices. 

While we understand how they work to protect against screens, we’ve begun to question the other benefits of wearing these glasses.

Blue light glasses and night blindness

Clear visibility is an integral part of safe driving for all involved: drivers, passengers and pedestrians.

With the low levels of natural light in the evenings, we have to compensate with car headlights, street lamps and other bright lights in order to see.

However, with the use of these artificial light sources comes an increase in glare, which greatly impacts our visibility while on the road. 

People with night blindness (nyctalopia) have difficulty seeing at night, including nighttime driving.

Nyctalopia makes it difficult for the eye to adjust to low-light environments causing blurred vision, cloudy vision, sensitivity to bright light or difficulty seeing into the distance.

Night blindness is not a condition itself, but a result of existing eye conditions, which presents differently depending on the underlying issue. Some common causes of night vision problems include:

  • Glaucoma
  • Cataracts
  • Nearsightedness (myopia)
  • Vitamin A deficiency

Similar to how blue light glasses filter light, night driving glasses have yellow-tinted lenses intended to block blue light coming from artificial light sources, reduce headlight glare and to improve visibility in low light conditions while on the road.

For those who experience night blindness, blurry vision, digital eye strain or other vision impairments, these lenses might not completely restore the ability to drive safely under certain circumstances.

Blue-light blocking glasses can help reduce eye strain and fatigue when driving at night, allowing for a more comfortable journey.

Although they may offer some relief from uncomfortable symptoms like headaches caused by prolonged exposure to bright lights after dark, you should consult your doctor to discuss what may be causing you to experience these symptoms.

Do blue light glasses work for night driving?

Car headlights and most street lights are now made with LED lights which emit high levels of blue light.

This can make driving at night challenging because of the blue light glare these bulbs cause, and when combined with existing vision issues, can make driving at night dangerous.

Simple blue light glasses may reduce glare and filter blue light from these LED lights.

Although many who wear blue light glasses claim that they have reported seeing positive effects on their overall health, there is no direct link showing that wearing blue light glasses or night driving glasses work to improve low-light visibility.

What type of glasses help with nighttime driving?

Although clear blue light glasses or yellow lenses may not be the best option for night driving, there are still other options to help improve our vision at night.

A great option might be to add an anti glare coating, or anti-reflective (AR) coating, to your next pair of prescription glasses.

While regular prescription lenses allow 92% of light to pass through the lens, anti glare coatings allow 99.5% of light to pass through, reducing the amount of reflections on the lenses.

image showing difference in vision while wearing regular lenses vs. anti-reflective lenses

Although they don’t filter high energy blue light, this reduction of reflections on your lenses in turn reduces the glare of oncoming headlights more effectively than yellow tinted glasses and blue light lenses.

This anti-reflective coating can also be applied to sunglasses allowing you to further reduce glare and protect your eyes from natural blue light like UV light and brightness from the sun during the day.

How can I improve my vision while driving at night?

Some ways to improve your vision while driving at night include:

  • Clean your glasses regularly because smudges can worsen glare.
  • Keep your windshield clear of all debris and streaks – dust and streaks can amplify the glare from light sources.
  • Try to keep your dashboard lights dim to reduce eye strain.
  • Utilise headlights to increase visibility, and keep them clean and fog free as this can dim their brightness.
  • Avoid looking directly at oncoming headlights.
  • Schedule regular check ups with your eye doctor to keep your prescription for your eyeglasses up-to-date, and catch any other issues that may occur.

The best solution might not be the same for everyone, and will depend on your overall eye health, needs and preferences, so it’s important to speak with your eye doctor immediately if you have trouble seeing or driving at night.

It's important to know your glasses measurements when buying eyewear online. This useful guide explains the significance of the numbers printed on your glasses and how to take the measurements yourself.
Eyeglasses measurements

In the past, shopping for eyeglasses involved tedious trips to eyewear stores, fitting frames, and perusing a few shelves of glasses. That’s not so much the case anymore; online retailers like SmartBuyGlasses have been established for years, and, as a result, there is a near-unlimited amount of colours, sizes, and eyewear designs on sale.

When buying online, knowing your glasses’ measurements is crucial. That is why we’ll explain what glasses measurements are and how to find them.

Eyeglass size explained

You may have noticed all glasses have three numbers engraved on the temples. They represent the glasses’ measurements: the lens width, bridge size, and temple arm length, respectively. Dots, dashes, or vertical bars usually separate these numbers. Some frames may have a fourth number, which refers to the height of the frames.

In some cases, acetate frames will have the eye size and bridge size on the nose pads on a plastic frame. All these glasses measurements are measured in millimeters (mm).

Eyeglasses frame dimensions
DID YOU KNOW?

Pupillary distance is the distance between your pupils. To have the clearest vision, the distance between the center of the left lens and the right lens should be the same as the distance between your pupils.

Eyeglass frame measurements

The frame width is the horizontal measurement of the frames, including hinges or designs that stick out at the sides. To measure the width of the frames, take a measuring tape or a ruler and measure the entire horizontal front of the frame from the further extended point to the other.

Eyeglass lens measurements

Lenses can be measured both in height and width. The lens height is the vertical measurement of the eyeglass lenses. This is important for bifocal lenses and progressive lenses. Lens width refers to the width of the lenses, which must be measured horizontally.

This typically ranges from 40 mm to 60 mm. To take these measurements, place the measuring tape on the lenses, first vertically, then horizontally, and only measure from one side of the lens to the other, ensuring no part of the frames is included.

How to measure your bridge size for glasses

The bridge size is the distance between the two rims or lenses of the eyeglasses where the nose pads are located. It typically ranges from 14mm to 24mm. Place the measuring tape right between the two lenses to measure the bridge and see how many millimeters are between the nearest points. 

How to measure your temple length for glasses

This refers to how long the temple is. Measure your temples from the hinge to the tip, and you’ll come up with the temple length. Usually, it’s between 120mm and 150mm.  

How to find out PD for glasses

The pupillary distance is another crucial measurement when ordering glasses online. To find out your pupillary distance, you can either use our online tool or do it manually with the help of a ruler.

Step 1: Standing in front of a mirror, hold the ruler up to the bridge of your nose or against your eyebrows.

Step 2: Close your right eye. While looking in the mirror, align the ruler’s zero with your left pupil.

Step 3: Keeping the ruler still, close your left eye and open your right eye.

Step 4: Read the number aligned with your right pupil’s center. This number is your pupillary distance.

Step 5: Repeat the process to ensure you get the most accurate result.

If you struggle doing it yourself, you can ask a friend to help you with this and check out our quick and easy tutorial.

I’ve measured my glasses

Now that you have all the information on your glasses’ measurements and know how to take them, it will be way easier when shopping online. Glasses’ measurements won’t be a mystery anymore, and you will confidently be able to choose the right pair of glasses.

If you need help determining what glasses size will fit best, we have an easy guide to help with that. You will have to measure your temples from one side to the other and check out our size table to find the recommended size based on your measurements.
