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.
