UV Light and Your Eyes

With Summer approaching it's time to think about your eyes and ocular health over the summer months. Unlike other cellular components in your body the human lens does not replace itself. Cells lining the GI tract, skin, and even blood cells are replaced by the body. This happens anywhere from 7 days to 7 years. The human crystalline lens does not replace damaged cells. Cataracts are the result of gradually accumulated damage to the lens. The biggest source of damage to the lens is radiation from the sun, in the form of Ultra-violet (UV) light. Another potential damaging source to the human lens is uncontrolled, or poorly controlled, blood sugar from diabetes. Cataracts diminish visual clarity, color vision, and can alter a person's spectacle prescription. An analogy that works well with cataracts is like frying an egg in a pan. The egg white starts out clear then turns cloudy and finally turns white. This process is similar to what occurs with the human lens over time. The process is slow and gradual. While it is occurring the person usually does not notice anything in the early stages. However when cataracts become more pronounced many patients report it's like looking through a dirty windshield. A second item that UV light can damage is the retina. The retina is the light sensitive tissue that lines the back of the eye and sends visual information through the optic nerve and back to the brain. It is similar to the film in a camera. I know I just dated myself since cameras no longer use film, but I like the analogy. The purpose of the cornea and lens is to filter out some of the harmful rays of the sun before it reaches the retina. Light focuses on the macula for our central vision. Over time the oxidative stress from UV light can breakdown the macula and result in Age-Related Macular Degeneration, ARMD. Please note, UV light isn't the only factor contributing to ARMD, but a significant one. The effects of ARMD are permanent and not reversible. It can lead to mildly blurred vision all the way to profound visual impairment. Proper nutrition and vitamin supplementation can improve the retina's natural defenses against the oxidative stress. Anti-oxidants such as Lutein, Zeaxanthin, and Mesozeaxanthin can help to reduce the impact of UV stress on the retina. A third item that UV light can damage is the conjunctiva. The conjunctiva is a clear membrane that covers the white part of the eyeball. Repeated sun exposure can lead to a condition called pterygia. This looks like a raised whiteish spot on the conjunctiva. It slowly grows and begins to cover the cornea. When it crosses over to the cornea is when most people begin to take notice of it. The condition is harmless and can be removed surgically. All these conditions can be mitigated by proper UV light protection. Polarized sunglasses, wide brim hat, and contact lenses with UV filters help to reduce the impact of the sun. Also, please note that these conditions are cumulative, meaning they add up from the time we were young. So please, encourage your kids and grandkids to wear sunglasses and hats.
