How-to Guide for Buying Sunglasses

Sure, sunglasses might add the final touches to your chic ensemble, but the real reason to purchase your shades is to protect your eyes from the sun. Not only does glare from the sun make it difficult to see, but the UV rays it reflects can cause permanent damage to your eyes and vision. You want to make sure your sunglasses offer optimal protection, fit, comfort and of course, the best possible vision. Here are some things to consider when purchasing your next pair.

UV Protection

There are two types of UV radiation, UVA and UVB. UVA rays are less intense yet more prevalent than UVB rays, making up 95% of the UV radiation that reaches the surface of the Earth. They have been linked to skin cancer, aging and the development of cataracts. UVB rays are very dangerous to the eyes and are the primary cause of sunburns and cancer. While they are dangerous year round, these rays are more intense during the summer months, especially mid-day between around ten in the morning and four in the afternoon. UVB rays also reflect off of snow, water, sand and concrete.

The damage caused by UV rays is irreversible and cumulative, building up over a long period of time. This is why it is important to start wearing sunglasses when you are young (also because your eyes are more sensitive at a younger age). You want to make sure your sunglasses block out 100% of UV rays. This is the most important factor to consider when purchasing your sunglasses.

Additionally, in certain circumstances of intense UV exposure, a condition called keratitis can occur, which is essentially a sunburn on the eye. Symptoms often occur hours after sun exposure and can include temporary vision loss and severe pain.

Sunglass Lens Options

Once you are certain your sunglass lenses have the requisite UV protection, you can begin to consider other lens possibilities. Here are some other lens options to consider:

Polarized Lenses:

Reduce glare from light reflecting off glass, water, snow, sand or pavement. You should consider polarized lenses if you participate in water or snow sports such as fishing, boating or skiing as the water and snow can create a strong glare. They are also great for comfort while driving by reducing glare and to enhance vision when on the road.

Tinted Lenses:

Certain lens tints enable you to see better or more comfortably under certain circumstances but you have to be careful. Lens tints can distort or reduce vision and some can even harm your vision by increasing your pupil size which leads to an increase of UV radiation penetrating the eye. Look for lenses with a medium tint that keep your eyes comfortable and do not have a negative impact on your vision. Your optometrists’ office can often make specific tint recommendations depending on your lifestyle or particularly activities (ex. golfing vs fishing) and the health of your eyes (for example, cataracts tend to cause more glare).

Photochromic Lenses:

Automatically darken when exposed to UV light. Photochromic lenses are a great option for individuals that wear prescription eyeglasses: one pair can serve you both indoors and outdoors. As soon as you step outside, the lenses will darken, and they’ll reverse when you go back indoors.

Lens Materials

There are also a few options when it comes to lens materials, such as plastics – including polycarbonate or acetate; trivex – which is a polymer material; or glass. The type of lens will determine the durability, clarity of vision and price of your lenses, so you should consider the factors that are most important for you and try out a few options to see how they feel.

Sunwear Frames

Frame Size

The size of your sunglass frame is important for both comfort and protection. Your frames should fit according to your face size and provide ample coverage for your eyes. When you try on your frames, make sure they cover your eyes and feel comfortable around the bridge and temples. Also check that they don’t slip off when you move your head down toward the floor.

Frame Materials

Frames can be manufactured from a number of materials and, these days, frame companies are constantly innovating to come up with new and improved options. These materials vary in strength, flexibility, weight, comfort and price. You need to choose a frame material that is comfortable, safe, and functional and that suits your lifestyle and your fashion style.

Making the Purchase

When purchasing sunglasses, keep in mind that your vision insurance may help to cover the costs when purchased at an optometry office rather than at a sports or recreation store. Check with your insurance and your local optical to find out about any discounts or coverage. Another advantage of purchasing from an optometrist’s optical is that the optician can help you to find the perfect pair to suit your eye and vision needs, as well as your lifestyle and fashion preferences.

The good news about choosing the right pair of sunglasses is that there are ample brands, colors, styles and materials to choose from. So when it comes to your shades, don’t settle for less than optimal protection, fit and comfort for your eyes.

Ultraviolet Light and your Eyes

If you want strong, healthy eyes and clear vision for life, a major step you can take is to protect your eyes from UV radiation. Wearing proper eye protection from the sun reduces the risk of a number of eye diseases and other conditions that are caused or worsened by UV exposure.

Eye Diseases Linked to UV Exposure

UV exposure has been linked to a number of serious eye diseases including macular degeneration and cataracts.

Macular Degeneration

Macular degeneration is a condition in which the macula of the eye breaks down, leading to a loss of central vision and is a leading cause of age-related vision loss. Macular degeneration develops over time so a lifetime of exposure to UV can contribute it’s likelihood.

Cataracts

Cataracts occur when the natural lens of the eye becomes clouded, resulting in blurred vision and eventually blindness. The len is responsible for focusing the light that comes into the eye, allowing clear vision. Cataracts can be treated by a simple surgery to replace the clouded lens with an artificial lens. UV light contributes to certain types of cataracts, which account for about 10% of all cases.

Skin Cancer

Another serious disease that can affect the eyes is skin cancer which can appear on the eyelids or the area around the eyes. Skin cancer is known to be linked to extended exposure to UV and your eyes can be a difficult area to protect with sun block as you don’t want it to get too close to the eyes.

Other Eye Conditions Linked to UV Exposure

Photokeratitis or Corneal Sunburn

Photokeratitis or a corneal sunburn in layman’s terms can occur with intense exposure to the sun without proper eye protection. It is commonly experienced after a day skiing or snowboarding at a high altitude or at the beach. Corneal sunburns can be extremely painful and can sometimes cause a temporary loss of vision.

Pterygium

Pterygium, also known as “surfer’s eye” is a growth that forms on the conjunctiva which is a layer over the sclera or the white part of your eye. Sometimes they grow onto the cornea as well. Often pterygia are harmless but if they grow too large they may begin to impact your vision. In this case, surgery may be necessary. Pterygia are commonly found in individuals who spend a significant amount of time outside in the sun or wind.

How to Properly Protect Your Eyes From UV

The more time you spend outside, the greater the risk for your eyes, however you can easily minimize this risk with proper protection. Here are a few tips to ensure you are doing what you can to safeguard your eyes:

Proper Sunglasses

Fully protective sunglasses should block out 99-100% of UV-A and UV-B rays. You can achieve this through purchasing a pair of sunglasses, applying a UV blocking coating to your glasses or opting for photochromic lenses which are eyeglass lenses which turn dark when exposed to sunlight. Most contact lenses will also have UV protection but this is just for the area of the eye covered by the lens.

Since UV exposure can enter from the air, the ground or from the sides, wrap-around and large lensed frames can provide added protection.

Add a Wide Brimmed Hat

A wide brimmed hat or visor will stop about half of the UV rays from even reaching your eyes as well as reduce the exposure coming in from the top or sides of your sunglass frames.

Know Your Environmental Risk Factors

UV exposure is largely dependent upon your location and your surroundings. If you are located at a high altitude you will likely be exposed to more UV than at lower altitudes. UV also reflects off of snow, sand, water and even asphalt so be aware that you are getting increased exposure under these conditions.

Know Your Additional Risk Factors

There are a number of other factors that can increase your exposure or risk of eye damage from UV. For example, certain medications increase the sensitivity of your eyes and skin to sunlight (speak to your doctor about any medications you are on). Previous eye surgery or eye diseases can also increase your risk factors for UV eye damage. Additionally if you work in certain fields such as welding or medical scans or radiation or use tanning beds, you can be exposed to additional UV radiation. If there is nothing you can do to change your exposure, make sure you are properly protecting your eyes with goggles or glasses and a hat.

Regular Eye Exams

Make sure you schedule a comprehensive eye exam on a regular basis to ensure your eyes are healthy. If you are over 50 or have increased risk factors for eye disease, you should schedule exams at least on a yearly basis or according to your eye doctor’s recommendations.
