How to Choose Sunglasses the Right Way

Sunglasses are more than just a fashion statement.  They should be used to help protect your eyes from the sun and its harmful UV rays.  However, it might not be that easy to know how to go about picking the right sunglasses for you.  There are a number of factors when considering how to choose sunglasses.

Here are the top five tips on how to choose sunglasses the right way.


    First and foremost, you should look at whether the sunglasses have any and enough UV protection.  The sun gives off radiation from its ultra violet rays that you will never feel or see.  The damage that both UVA and UVB rays can cause to your skin and your eyes can be significant, especially over your lifetime.  In fact, too much exposure to UV light has been shown to cause cataracts and will destroy the retina.  The sunglasses that you choose should protect your eyes somewhere between 99 and 100% of the sun’s UV rays.


    It is important that you understand that the darker the lens are, it doesn’t mean that there’s greater protection from UV rays.  However, despite this, the darker the lens are, the better the sunglasses will be at protecting your pupils.  Your pupil controls how much light gets into the eye.  What this means is that the darker your lens are, the better protection for your eyes because your pupils will not open up and let as much light in as it would if the lens were lighter.  Thinking about UV protection and the darkness of the lens, you might be realizing that some of the sunglasses you own or have worn in the past might have offered very little to no protection, which can be extremely damaging to your eyes!


    The type of lens that you have is an important factor when considering how to choose sunglasses.  Are the lenses made from glass or plastic?  Are they curved or straight?  Sunglasses are on your face, right near your eyes, so it is important to find sunglasses with lenses that are safe and that do not distort your vision.  If you require corrective lenses, you may wish to make sure that you get sunglasses with lens that can help you with your vision (particularly in the event that you might not want or wish to wear contacts).


    This might sound like common sense, but many people will opt for sunglasses that don’t fit properly, simply for a look they are going for.  It is important to make sure that your sunglasses fit properly to avoid letting in any UV rays in or near your eye.  It should fit snug to the face.  Not so close that it’s touching your eyelashes, but it should not be pushed too far away either.  It is also helpful to get sunglasses that line up to your eyebrows.  There are also sunglasses that wrap around your face, which can help block out any UV light from the side.


    If you are out at the beach, in large bodies of water, or like to spend time in the snow, then finding sunglasses with polarized lenses are a must for you.  Polarized lenses are used to help reduce the glare from these environmental factors.  However, it is not to be confused or mistaken for UV protection.  Polarized lenses will allow you to see better when there’s a lot of light and glare around you.

    In conclusion, we hope that the above tips will help you pick out the next pair of sunglasses that are just right for you.  You are only given one set of eyes in your lifetime – – it’s imperative that you make sure that you take the time to do your best to protect them.

    One last final tip to take into consideration.  While deciding how to choose sunglasses, it is important that you consider all of the above factors, read the labels, ask questions, and make an educated decision when picking out your sunglasses.  A lower price does not necessarily mean lower quality, the same way a higher price does not mean the best quality!  So, be on the lookout for what’s going to fit and protect you the most!

Negative Effects of UV Rays on Eye Health

Most people are aware of how harmful ultraviolet (UV) radiation is to the skin. However, many may not realize that UV rays can harm the eyes and affect their vision.

Exposure to excessive amounts of UV radiation over a short period of time can cause extreme sensitivity to light and excessive tearing. It can be painful and feel like a sunburn to the eye. The longer the eyes are exposed to UV radiation, the greater the risk of developing eye disorders such as cataracts or macular degeneration. Fortunately, sun protection and preventative options are available to offer UV protection.

Types of UV Radiation

There are three types of UV radiation:

UV-C rays are the highest energy UV rays, and potentially the most harmful to eye and skin health. Fortunately, it is absorbed by the ozone layer, virtually blocking all harmful UV-C rays. If, however, the ozone layer depletes, high-energy UV-C rays could potentially reach the earth’s surface and cause serious health problems.

UV-B rays emit lower energy than UV-C rays. These rays are partially absorbed by the ozone layer, but some still reaches the earth’s surface. In low doses, UV-B radiation can stimulate the production of melanin, causing the skin to darken. In higher doses, however, UV-B rays can cause sunburn that increases the risk of skin cancer, premature aging of the skin, and wrinkles.

In high short-term exposure, UV-B rays can also cause photokeratitis, a painful inflammation of the cornea.

UV-A rays have lower energy than UV-C and UV-B rays, but it can pass through the cornea and reach the lens and retina of the eye. Overexposure to UVA radiation can cause the development of cataracts and the development of macular degeneration.

How Do UV Rays Affect Eye Health?

Short and long term exposure to UV radiation can harm the eyes, affect vision, and compromise overall eye health. Eye diseases and conditions caused by exposure to UV radiation include:

  • Macular Degeneration, also known as AMD, is caused by damage to the retina over time. It is the leading cause of age-related blindness and extended exposure to UV light may increase the risk of developing this condition.
  • Cataracts are a condition in which the natural lens (the part of the eye that focuses on light we see) is clouded. Exposure to UV light, especially UV-B rays, increases the risk of contracting cataracts.
  • Pterygium, also known as surfer’s eye, is a pink, non-cancerous growth that forms on the layer of conjunctiva. Exposure to UV light increases the risk of developing these growths.
  • Skin cancer in and around the eyelids is also associated to extended UV exposure.
  • Photokeratitis, also known as corneal sunburn, is the result of high short-term exposure to UV radiation, especially UV-B rays. Long hours at the beach without proper eye protection can cause this condition, and it can be very painful. It can also cause temporary vision loss.

Prevention and Treatment

We all use sunscreen to protect our skin from harmful UV rays. Protecting our eyes is just as important. Sun damage to eyes can occur anytime during the year, and prevention is the best treatment. Be sure to wear UV-blocking sunglasses and broad-brimmed hats whenever you are outside. Never look directly at the sun, which can damage the eye’s retina.

To provide adequate protection for your eyes, choose sunglasses carefully. They should:

  • Block out 99 to 100 percent of both UV-A and UV-B radiation;
  • Screen out 75 to 90 percent of visible light;
  • Have lenses that are perfectly matched in color and free of distortion and imperfection
  • Provides more coverage such as over-sized glasses

Additional precautions include:

  • Do not use sunlamps, tanning beds, or tanning booths
  • Wear UV-blocking goggles when surfing, swimming, or snowboarding
  • Wear a wide brimmed hat when outdoors
  • Avoid prolonged exposure to direct sunlight by staying in the shade, especially between 10am and 4pm

If your eyes are ever impacted by UV rays to an extent that you believe could be causing vision problems, you need to see an eye doctor immediately.

How the Sun Can Affect Your Vision

Bright Eyes: Effects the Sun Can Have on Your Vision

Sporting those summer shades aren’t just for looking cool. UV light can damage eyesight in a serious way. Ultraviolet (UV) radiation is getting more attention regarding the dangers of skin damage and how it can cause cancer. However, UV radiation and eye damage is also a major concern that should be taken seriously. Protecting your eyes is crucial in your current and future eye care.

Shedding Some Light on UV Radiation

The sun is dangerous as a result of UV light or radiation. However, this type of light and radiation can come from other sources like tanning beds, lasers, and welding machines. UV radiation comes in various types: UV-C, UV-A, and UV-B. Since UV-C is absorbed by the ozone layer, it poses no threat or danger to human beings. However, UV-A and UV-B radiation can have damaging effects on skin, eyes, and your vision. UV Light directly impacts eyesight by causing many eye diseases and conditions. Eye conditions that result from exposure to UV rays include the following:

  • Macular Degeneration (AMD) – Damages your retina and is the leader in age-related blindness
  • Cataracts – Causes clouding of the eye’s natural lens
  • Pterygium – Commonly known as “surfer’s eye” and is a pink, non-cancerous growth. It forms over the white of the eye
  • Skin Cancer – Can develop around the eyelids when exposed to UV light
  • Photokeratitis – A corneal sunburn that can be extremely painful or result in temporary vision loss

Risky Business

Anyone can be at risk for eye damage from UV light. If you are exposed for long periods of time in the sun without sunglasses, this can increase your risk. Here are other ways you can be at risk:

  • Using a tanning bed or sunlamp
  • If you have a preexisting condition such as cataracts or a retinal disorder
  • Certain medications can increase your risk because they cause higher eye sensitivity to light (these can include tetracycline, sulfonamide drugs, birth control pills, diuretics and tranquilizers)
  • If you’re a welder or medical technologist

Protect Yourself

Now that you know the dangers of UV rays on vision, there are many steps you can take to protect your eyesight. If you wear adequate eye protection and a sun hat, this should help a great deal. When looking for sunglasses, they should have the following specifications:

  • Sunglasses that block UV-A and UV-B radiation by 99-100%
  • They should screen out visible light by 75-90%
  • Buy grey lenses – they cause proper color recognition
  • Use wrap around frames for extra protection if you spend a lot of time outside

If you have children or teenagers, make sure that you share these tips with them as well, as they usually spend more time outside. It’s also important to go to your eye appointments and get an exam at least every two years. This is a good habit for maintenance of your vision and for any more information you want to know about eye health related to UV rays.

Prescription Sunglasses For Modern Living

Prescription Sunglasses Designed for You

If you’ve ever found yourself driving directly into the sun, you can relate to this experience – the sun is in your eyes, you’re struggling to get the visor in the right position, and you’re squinting at the cars passing you by. Most drivers keep a pair of sunglasses handy, but most sunglasses don’t work for you. What you need is a pair of prescription sunglasses so your eyesight isn’t compromised.

People who normally wear eyeglasses or contact lenses have a tendency to put off purchasing prescription sunglasses until it becomes an absolute necessity. A word of advice? If you wear prescription lenses on a daily basis, prescription sunglasses are worth that extra investment.

Prescription Sunglasses Benefits and Options

Available in photochromic lenses: these are eyeglasses that are clear indoors and become dark when you are outdoors in the sunlight. Transition Lenses are similar although they don’t always fully clear when indoors and may not darken enough when you’re in those uncomfortable driving situations.

If you are a patient with contact lenses, you may also want to consider prescription shades for outdoor use, as there is no Transition option for contact lenses. You may not always want to wear your contact lenses to places like the beach where you are up against sand, wind, and water, which could make your eyes itchy and/or even infected.

Additionally, you can wear your prescription sunglasses the same way you like to wear your regular prescription eyeglasses out at the lake (or ocean), for example. Contact lenses could be exposed to bacteria close to the water and cause an eye infection upon contact.

Wearing non-prescription sunglasses over your prescription glasses may not provide enough UV protection for your eyes, and that’s never a good idea. With prescription sunglasses you are doing your eyes a favor.

Patients who choose contact lenses as their every day option will have an outdoor and active option to avoid uncomfortable or possibly infectious situations for their eyes, and patients with prescription eyeglasses can swap their pairs for an option more amendable to sunlight.

Individual eye prescriptions must be tailored to the person wearing the sunglasses. Prescription sunglasses can be made to fit any prescription, from myopia (nearsightedness), hyperopia (farsightedness), bifocal lenses and progressive lenses, to astigmatism.

If you have presbyopia and you use your lenses to help you read a magazine or book at the beach, there are options available for you as well. Prescription swimmers’ goggles have also been made available for those who like to see underwater.

Prescription Sunglasses Frame Styles and Options

Similar to non-prescription sunglasses and prescription eyeglasses, prescription sunglasses come in a variety of frame styles, from all of your favorite fashion designers and celebrity brands. However, if cost is a concern, it is not necessary to buy the designer, fashion, and celebrity brands. For the budget minded, they can also be bought at discount prices from discount brands online and in-store.

You may also want to consider polarized, as opposed to tinted, lenses in your prescription sunglasses. Regular sunglasses diminish the amount of horizontal and vertical light that filters through the lens from the sun. With polarized lenses, there is a chemical filter that absorbs and filters out horizontal light and only allows vertical light to pass through the lens. This function eliminates the glare that can be experienced with traditional sunglasses.

If you are a prescription eyeglass or contact lens wearer who isn’t happy with what you’ve had to use up until now, you may want to spend the extra money on prescription sunglasses or even polarized prescription sunglasses. You won’t have to sacrifice style and you can save on the cost if you look in the right places.

How Sunglasses Can Save Your Eyesight

In addition, to being a must-have fashion accessory, sunglasses are an important tool for keeping your eyes safe from harmful UV radiation. UV exposure can increase your risk for developing eye related diseases such as cataracts, age-related macular degeneration and even cancer of the eye and eyelid. And because ultraviolet rays can have a detrimental effect on your eyesight, it is imperative to wear good quality sunglasses to protect your eyes from harm.

Things to Consider

The damage caused by UV rays is cumulative and may not appear until later in life which is why it is so important to start protecting your eyes at an early age. Children are particularly susceptible to the harmful effects of UV radiation. This is because their pupils are much larger than adults and therefore they take in more UV rays. Because of this, it is important for parents to always to make sure their children have sunglasses on when they are outside for long periods.

Sunglasses don’t just protect your eyes from UV radiation they also protect them from dust and other airborne particles that may harm your eyes.
Non-prescription sunglasses are just as protective as prescription sunglasses provided they have the same UV protection and lens size.

While you can find contact lenses that are designed to protect your eyes from UV rays they do not provide comprehensive eye protection because they leave your eyelids exposed. And because the eyelids are a frequent cancer location, it’s important for those whose wear contacts also wear non-prescription sunglasses.

You should always wear your sunglasses when you’re outside, but it’s especially important to wear them during peak sunlight hours roughly between 10 a.m. and 2 p.m. when the UV rays are at their strongest.

You should wear sunglasses even when it’s cloudy outside to protect your eyes from UV rays.

Wearing a wide brim hat can also protect your eyes from UV radiation. Try pairing with sunglasses for maximum protection

Be sure to wear sunglasses all year round not just in the summer months.

An added benefit to wearing sunglasses is that they protects your eyes from developing wrinkles and other signs of aging.

What to Look for When Choosing Sunglasses:

  • Look for sunglasses that block 99 to 100% of UVA and UVB rays.
  • Those that do a lot of driving or boating should consider getting polarized sunglasses to reduce glare.
  • Bigger sunglasses offer better protection.
  • Costly sunglasses do not necessarily provide the best protection.
  • Darker sunglasses do not necessarily protect better than tints. Always read the label and base your choice on the amount of UV protection they provide.
  • When in doubt speak to an eye care professional before making a purchase.
