Ray-Ban Sunglasses Lenses

rayban sunglasses

Ray-Ban has a rich history dating back to 1936. As the best-selling designer sunglasses brand worldwide, Ray-Ban continues to innovate with revolutionary eyewear while staying true to their Ray-ban classic designs. 

The brands iconic status is likely due to the high quality, superior performance and comfort of its glasses.

Ray-ban sunglasses offer a wide variety of lenses, with each one having its own unique characteristics and purpose. Our guide will lead you through the different types of Ray-Ban sunglass lenses to help you get a better idea of which lens is right for you.

Solid colour lenses

As the name implies, this type of Ray-Ban sunglasses lens comes in a solid colour. They are also non-mirrored and non-polarised.

  • Green classic G-15: Similar to the story of Ray-ban Aviator sunglasses, the Classic Ray-Ban G-15 lens was originally developed for military pilots in 1937. It has a solid green colour and operates in low light to sunny conditions. These sunglasses offer a high level of clarity, comfort, protection and more accurate vision by absorbing 85% of visible light and filtering out most blue light as well as achieving outstanding colour contrast.
  • Brown Classic B-15: As the twin to the Ray-Ban G-15 lenses, it offers the same high performance with a high level of clarity, comfort, and protection. However, brown lenses provide greater contrast in low light conditions and perform better on cloudy days.

Gradient lenses

The tint in Ray-Ban gradient sunglasses recedes from top to bottom, so the lenses are darkest at the top and gradually recede until there is no tint at the bottom. 

Therefore, the lenses offer complete clarity of vision and protection from harmful UV rays. These features make gradient lenses a great option for driving.

Thanks to its precise chemical immersion process, the plastic Ray-Ban sunglasses lenses attain a receding transition from a dark to light shade. 

In contrast, high vacuum processes make the crystal lens tinted on the back, allowing for smooth colour transitions.

Polarised lenses

Ray-ban polarised sunglasses have lenses that are fantastic for those who do a lot of sporting activities such as daytime fishing, skiing, mountaineering, hiking in snowy areas or even sunny highway driving, as it helps to reduce glare. 

Ray-Ban Polarised sunglasses only allow light to enter the lens vertically and block any light that reflects from a horizontal surface such as light bouncing off water or a field of snow. These lenses are easily identifiable as they have a “P” following the lens logo.

Chromance lenses

Ray-ban Chromance is a revolutionary new lens technology for those who love colour. All Ray-Ban Chromance lenses intensify colour as well as recognition which gives the perception of brighter and more vibrant colour.

The lenses enhance contrasts, filter harmful UV rays and eliminate glare as well as reflections. As a result, Ray-Ban chromance lenses can sharpen your visual field, optimise vision and improve your experience. 

They meet the demand of a fast-paced urban lifestyle and are perfect for challenges faced in a sporting environment.

Mirror lenses

The mirror coating applied to this lens makes your Ray-Ban sunglasses look like small mirrors, a feature that not only looks great but also has major functional benefits. 

The Ray-ban mirrored sunglasses coating is made by fusing superheated metal oxides to the lens at a molecular level to ensure a uniform layer. 

Reflective lenses block sun glare while providing a strong colour contrast in order to help your vision remain clear and crisp. Additionally, the mirror coating hides your eyes so that they are not visible through any reflective lenses which gives you a unique look.

Silicone Hydrogel Lenses

Silicone Hydrogel Lenses

silicone hydrogel

Arguably the main preoccupation of contact lens developers over the years has been increasing oxygen permeability. If worn for an extended period of time, traditional contact lenses deprive the cornea of much-needed oxygen. 

Without adequate oxygen, the cornea dries out and can become inflamed, which is a condition known as keratitis. 

This can cause itchiness and pain, and in more severe cases, can impair vision and lead to long-term damage such as scarring. 

In the quest to find a longer lasting, comfortable contact lens, the ability to improve oxygen permeability is crucial. Thus, silicone hydrogel contact lenses have been a game-changer for all contact lens wearers.

Silicone hydrogel

Soft contact lenses were first created in the 1960s, after the development of ‘hydrophilic gels’ or hydrogels. 

Problems of keratitis became more widespread with the introduction of extended wear contact lenses in the 90s because more people were wearing contact lenses for longer periods of time. This resulted in many people getting infections.

The first silicone hydrogel contact lenses were introduced to the public in 1999. 

This amazing new technology allowed up to seven times more oxygen to reach the cornea compared to traditional hydrogel lenses, meaning that for the first time extended wear contact lenses did not lead to an increased health risk.

Oxygen permeability

The higher permeability of silicone means that the oxygen permeability of silicone hydrogel lenses is not tied to the amount of water in the lens. 

For the wearer, this means increased comfort, and the ability to wear the lenses continuously for an extended period of time. 

Studies have also shown that any infections that do occur tend to be less severe than with traditional Hydrogel lenses.

Contact lenses for dry eyes

Whilst they are not perfect, there is no denying that Silicon Hydrogel represents a major step forward in contact lens technology, and it is no coincidence that the market has been heading in this direction for some years now. 

Whilst they may not be for everyone, almost any contact lens wearer is in a position to try them out, though we will always recommend that you consult your optician before switching your contact lenses. 

People who stand to benefit the most from Silicone Hydrogel contact lenses are those who tend to wear their lenses for more than twelve hours a day, particularly if they spend a lot of time in low humidity environments (offices with air-conditioning is one example of this). 

How to choose the right contact lenses

What are the differences between daily and monthly contact lenses? Choosing the right contact lenses for your needs comes down to two main things, your prescription and lifestyle.

Daily contact lenses are typically thinner than monthly contact lenses and have high water content. 

1 day silicone hydrogel contact lenses should for example be word for around 12 hours a day and then removed overnight to let the eyes rehydrate. 

Residue from the eye easily build up and affects the quality of the lens. Therefore, daily contacts should be disposed of and not reused after wearing them. 

If you play sports or engage in outdoor activities, daily contact lenses may be the better option for you as the lenses are likely to be exposed to dirt and can be replaced daily.

Monthly lenses are thicker and durable, making them more long-lasting. They do not dry out as easily if properly taken care of and stored and can therefore be reused multiple times. 

Your vision correction needs is important when choosing contact prescription lenses. Since monthly contact lenses are made with a harder composition, they are more suitable for prescriptions that require higher magnification. 

If you have a complex prescription, monthly lenses are typically more suitable for you.

If you have sensitive or dry eyes, silicone hydrogel contact lenses are a good option and together with your eye doctor you can discuss the perfect fit for your needs.

How to Reduce and Prevent Eye Strain

eye strain

Eye strain often occurs when you use your eyes to focus on something for a long period of time. 

Eye fatigue is a result of tired eye muscles and while it does not cause any damage to your eye health, it can often be uncomfortable and make participating in everyday tasks difficult. 

Read on to discover the steps you can take to prevent and reduce eye strain now.

Eye strain causes

There are many factors to consider when trying to determine what is causing your eyes to strain. If you spend a lot of time at the computer, you might be suffering from digital eye strain. 

Eye fatigue can also be caused by reading, working in poorly lit rooms, or almost any task that requires consecutive hours of visual concentration. 

The most important step to take first is determining what activity is causing the problem so you can look for ways to prevent your eye strain from reoccurring. 

Prevent or reduce digital eye strain

If you have eye strain and work at the computer or regularly spend more than one hour at a time on digital devices, it’s possible that you’re experiencing digital eye strain, also known as computer vision syndrome (CVS). 

Reducing glare from your screen is one way to prevent digital eye strain while at the computer. 

Eye strain relief

One of the simplest ways to achieve rapid eye strain relief is to take a break from focusing your sight on the task at hand and allowing your eye muscles to relax. While it may seem obvious, you should also remind yourself to blink often. 

This is because when we focus our eyes for a long period of time we can, unintentionally, stop blinking as often as we should. 

When you first notice you’re experiencing eye strain, the best thing to do is to step away, relax your focus, and blink. 

Night driving glasses to reduce eye strain

If you notice you tend to get eye strain when you drive at night, this could be the result of light glare from oncoming traffic and street lights. 

Anti-glare coating on your glasses could protect you from this type of eye strain when you are driving late. 

SmartBuyGlasses’ Arise collection comes with free anti-glare lenses on the most popular styles such as these Arise clear frame glasses.

Eye strain headaches

Eye strain is a common complaint among migraine patients. If you experience eye strain due to migraine headaches, this could be caused by photophobia, also known as light sensitivity. 

In this case, you should consider a pair of polarised sunglasses. Polarised glasses are designed to block harmful rays from entering the eye and causing conditions that might lead to eye strain. 

Eye strain due to headaches could also be a sign that you might need vision correction. If your eyes are working harder than they should be to see things near or far, this could lead to eye fatigue and even headaches. 

Adults are recommended to have an eye test every two years, and children once a year.

What to Do About Watery Eyes

watery eyes

Watery eyes, also known as teary eyes or weeping eyes, is a common complaint for people of all ages. Watery eyes are especially common for infants, as their tear duct can be slow to fully develop and open. 

A tear duct is a small tube that allows your tears to drain from your eyes to your nose. Adults can also have problems with their tear duct, such as a blockage, which will result in itchy watery eyes. 

Other common causes of watery eyes include seasonal allergies, viral infections, foreign objects in the eye, some medications, aging, and even dry eyes.

Watery eyes treatment

  • Foreign Object: If there is a foreign object in your eye, such as an ingrown eyelash, your doctor will remove it and that should solve your watery eye problem.

  • Bacterial Infection:In cases of a bacterial infection, such as pink eye, your doctor may prescribe you some form of antibiotics.

  • Blocked Tear Duct: If you have a blocked tear duct, your eye care professional may perform an outpatient procedure to help flush it out with a saline solution.

  • Seasonal Allergies: If you have watery eyes due to seasonal allergies, you might want to consider getting a pair of protective sunglasses while you are outdoors.

  • Dry Eyes: If your watery eyes are a symptom of dry eyes, you might be prescribed eye drops to help solve the dry eyes and eliminate the symptoms.

How to put in eye drops

While the thought of putting in eye drops can scare some people, it is actually a rather simple process. When you are prescribed eye drops for watery eyes, your doctor should give you specific instructions on how to apply eye drops.

After you put in eye drops for watery eyes

Always be sure that when you use eye drops for watery eyes, you do not touch the actual bottle to any part of your eye. The eyes are very delicate and doing so could risk scratching the cornea or spreading germs. 

When you’re learning how to use eye drops, it is important to remember that once they have been applied, you should close your eyes, rather than blink. 

This will stop the eye drops for watery eyes from escaping before they have a chance to be effective. Lastly, you should wipe any unabsorbed drops with a tissue and wash your hands.

How to Get Rid of a Stye

eye stye

A stye is a red bump near the eye that can resemble a pimple inside eyelid, or more commonly, outside the eyelid. 

Styes are also known as a hordeolum. Styes are typically puss filled and can cause discomfort or swelling near the eye. 

While not usually an indicator of a serious medical condition, you should see your eye care professional if the stye does not go away on its own.

Stye causes and symptoms

Styes are caused by an infection of the oil gland around the eye. Styes are a lot like chalazions which look the same, but usually indicate a non-infected swelling of the oil gland.

Stye symptoms can include a red pump near the eyelid, or eyelid pain. This pain can increase when you touch the infected area. You may also experience swelling or tearing of the eye. 

You could get a stye on upper eyelid or a stye on lower eyelid. Finally, you could have a stye on the outside of your eyelid (external hordeolum) or on the inside.

How to get rid of a stye

Styes typically go away on their own in a couple days. However, your eye care professional might prescribe stye medication such as eye drops or an antibiotic cream to help get rid of a stye fast.

If the infection has spread beyond the eyelid, they might prescribe a stye medication antibiotic in tablet or pill form.

Stye relief

While there often isn’t much to do but wait when it comes to how to get rid of a stye, there are a few things to try to relieve the pain. 

While these home remedies are sure to bring you some stye relief, there are people who claim these methods could also help you get rid of a stye:

  • Wash with Soap and Water: washing the area of the stye with soap and water to gently remove any eye drainage.
  • Apply Wet Washcloth: apply a warm, wet washcloth over the stye to help relieve the pain. Make sure the water is warm and not too hot, to avoid irritating the area further.
  • Don’t try to pop it: popping a stye could cause the infection to spread to other areas of your face.
  • Avoid Contact Lenses: try not to wear contacts until your stye clears up as it could spread infection to your eye. Don’t have a pair of backup glasses? Shop SmartBuyGlasses’ collection of designer eyewear today for cheap prescription glasses delivered right to your door.

The Best Eye Health Supplements

The human body is complex, and the eye especially so. In order to function properly, your eyes need care. Part of that comes from the vitamins and supplements you eat or drink. 

Use this guide to see which are the best vitamins for eyes and what kind of supplements you can add to your diet to maintain your eye health.

While tablets are always an option for upping your vitamin intake, the best way is always natural – there are so many good foods out there that can better your eye health. 

This list is chock-full of natural solutions to supplement your eye health.

Vitamins

  • Vitamin A is important for ensuring your eyes are adjusted to low light settings. Famously, carrots are supposed to boost your night vision! While this claim isn’t exactly scientifically substantiated, carrots (as well as pumpkin, sweet potato, kale and cod liver oil) do contain a good amount of Vitamin A.

  • Vitamin B1 reduces inflammation, and there is some evidence to suggest that it may help prevent cataracts. Obviously, claims like this must be taken with a pinch of salt, but there’s no harm in adding extra vitamins to your diet where you can. If you’re looking for Vitamin B-rich foods, try wholesome ingredients like whole grains, eggs, almonds, avocados and spinach.

  • Vitamin C helps maintain the collagen in your cornea, the capillaries in your retina, and reduces the risk of cataracts. You may already be familiar with some foods that contain Vitamin C like citrus fruits, but it’s worth looking elsewhere too. Berries, broccoli, peppers and kiwi fruit are all jam-packed with Vitamin C!

  • Vitamin E, like some of the other vitamins on this list, allegedly helps to reduce the risk of macular degeneration and cataracts. When taken with selenium, your body can quickly absorb it – luckily, some superfoods contain both! For supplements full of Vitamin E, try Brazil nuts, seafood, whole grain cereals and sunflower seeds (though maybe not all at the same time).

Dietary supplements:

  • Omega-3 Fatty Acids are believed to be particularly important in the development of vision in infants, alongside helping to drain intraocular fluid from our eyes – reducing the danger of high eye pressure and glaucoma. They also reduce the chances of getting dry eyes. Most commonly found in seafood, the best place to find omega-3 is in oily fish like salmon, mackerel and sardines.

  • Zinc can help out with your body’s absorption of Vitamin A – meaning it’s a pretty good dietary supplement if you’re looking to boost your eye health. Zinc is found in seafood, beef, eggs, tofu, beans, nuts and whole grain cereals. It’s a fundamental component of our immune systems, so incorporate it into your diet, but try to steer clear of overdoing it with extra supplements as an excess can get you into some difficulties down the road.

  • Lutein and Zeaxanthin are carotenoids, i.e. pigments found in plants and in your retina. Supplementing these pigments helps increase their density in your retina. They also absorb excess amounts of harmful blue and UV light. If you want some great lutein boosters, start from the ground up – dark leafy greens, peas, summer squash, pumpkin, brussels sprouts, broccoli and asparagus are all great naturally occurring sources that can really help!

  • Herbal Supplements are also a great way of getting in some extra nutrients – green tea is great for Vitamin C and E, chrysanthemum flowers are known for their Vitamin B levels, and wolfberries are known to improve eyesight, moisten dry eyes and prevent macular degeneration.

How to Relieve Tired Eyes

woman having tired eyes

While heavy eyes could be a sign of overall body fatigue, the term “tired eyes” is usually another way of referring to eye strain. Eye strain occurs when the muscles in your eyes are overused and become tired. 

While tired eyes do not cause any eye health damage, they can make everyday tasks more difficult to complete. Tired eyes might also be caused by outside conditions such as headaches or computer vision syndrome. 

Read on for more information surrounding eye fatigue symptoms, causes, and remedies.

Eyes feel heavy

Symptoms of tired eyes could include trouble focusing, irritated eyes, sensitivity to light, watery eyes, dry eyes, and a sore neck, shoulders, or back. 

One characteristic of eye strain might be the sensation that your eyes feel heavy. This can be a result of focusing your eyes for long periods of time, without properly resting them.

Tired eyes occur when the eye muscles have not had the opportunity to rest after intense or long periods of use. Some activities that might give you tired eyes could include driving, reading, and excessive screen time. 

These activities all require you to visually focus on a task for an extended period of time, resulting in eye fatigue. 

While tired eyes are usually a result of eye muscle overuse, in some rare cases, heavy eyes could also be a sign of an underlying eye health problem.

Remedies for tired eyes

Solving eye fatigue is usually a matter of changing your daily habits. That is why there are plenty of at-home remedies for tired eyes that you can try. One way to get rid of tired eyes is to work on a task under proper lighting. 

Poorly lit areas could result in tired eyes as the eye muscles have to work harder to see. Another way to avoid tired eyes is to take longer, more frequent breaks from visual focusing activities. 

This will allow your heavy eyes a chance to rest and recuperate.

Other ways to treat eye fatigue could include limiting your screen time and choosing the right eyewear for you. 

Wearing glasses for driving, reading, and using the computer is a great way to prevent tired eyes.

Do I Need Glasses?

eyeglasses

How do I know if I need glasses? Let us help you determine the most common signs you need glasses, how often you should have an eye exam and the best glasses for your vision problems.

The signs you need glasses:

There are many online ‘Do I Need Glasses’ quizzes you can take if you’re concerned you might need glasses. The common symptoms include:

  • Blurry vision: This is often a sign of astigmatism as well as short-sightedness and long-sightedness. If objects aren’t appearing clearly, it will cause fatigue and eye strain, so glasses can be a great solution.
  • Squinting and eye strain: Are you straining your eyes in order to see things near or far? This is a symptom that you need glasses.
  • Headaches: If you work long hours at the computer you should be wearing glasses with blue light protection to reduce headaches and eye strain.
  • Trouble seeing clearly at night-time: This could be a sign of cataracts or short-sightedness, so it’s important to see your optometrist for an eye exam if you’re experiencing difficulty seeing at night.
  • Rubbing your eyes: This is particularly common in children. You may just have an eye allergy, or you could need glasses.
  • Your parents wear glasses: bad vision can be genetic so it’s important to have an eye exam if close family members wear glasses.

How often do I need to get an eye exam?

Depending on your age and eye health, it is generally recommended by optometrists to have an eye test every one to two years.

  • Children’s eye examsshould commence from 6 months of age. They should receive another eye test at three years old and another before they commence school.
  • Adults 18-60: Every two years
  • Adults 61 and older: every year
  • At risk people:If children or adults have a history of poor eye health in the family, more frequent eye exams are recommended.

Online eye test

It’s important to visit an optometrist to check the health of your eyes as no online test is currently able to do this. Additionally, eye tests online aren’t able to provide you with new prescription details. 

There are some eye tests online that help to determine how good your level of vision is, but they should always be taken in conjunction with visits to your optometrist every two years.

The Best Blue Light Glasses for Kids

kids eyeglasses

According to the Kaiser Family Foundation, an American nonprofit focused on major healthcare issues, the average screen time for kids ages 8-18 is about 7.5 hours a day. 

Exposure to blue light emitted by these screens could potentially cause or worsen symptoms of insomnia, migraine headaches, eye strain, and other health issues. 

As technology becomes more ingrained in our society, there are tools that can help minimize or eliminate eye health risks, such as kids’ blue light glasses.

What Causes Bloodshot Eyes?

bloodshot

Bloodshot eyes are a common eye affliction that everyone gets. There are many different bloodshot eyes causes, and many ways to prevent bloodshot eyes. Take a look at our guide below.

Pink eye

Also known as conjunctivitis, pink eye is very common. It is when the eyelids and the conjunctiva (liquid film which coats the eye) are inflamed due to allergies and viral or bacterial infection. 

Red lines appear because the conjunctiva contains blood vessels that dilate when irritated, thereby causing the red colour.

Tears

Tears are essential to lubricate the eye and keep it moist and healthy. If your tear ducts aren’t producing enough tears, then your eyes become dried, irritated and itchy as well as inflamed. This then leads to a red eye. Ask your doctor for eye drops.

Computer use

Our eyes become bloodshot when they are dry. So what causes dry eyes? When you spend too much time staring at electronic screens, you may experience “Computer vision syndrome”. 

This happens when the eye becomes strained from looking at a screen for too long, and doesn’t blink as often, leading to dry, inflamed eyes. Eyes may then appear red and bloodshot as a result. 

Thus, try to remember the 20/20 rule; after every 20 minutes of screen time, look away at something 20 feet away for 20 seconds. This is a great way of how to prevent bloodshot eyes.

Painful red eyes

If your eyes are red and painful, or have reduced vision, higher sensitivity to light, then go to your doctor for medical attention as soon as possible. 

These could be signs of a serious condition such as glaucoma, uveitis, ocular herpes, or a corneal ulcer.

Smoking and drinking

Alcohol reduces the oxygen levels in your red blood cells, which can cause blood clotting in your eyes and produce a red colour.

Tobacco smoke is a toxic substance that irritates the eyes, dry it out, and increases the risk of contracting a host of diseases such as cataracts. Cannabis dilates the blood vessels in the eye quite significantly for long periods of time.
