National Sunglass Day is June 27th and to support the cause and the Vision Council Visualites is going to offer 50% OFF our Polarized sunglasses. Everyone know that sun exposure is harmful to our skin, but did you know that UV rays can cause serious damage to your eyes that can in some cases lead to blindness?
Over time exposure to the sun and UV-A and UV-B rays, the two types of rays that damage the eye can contribute to several issues. Some of the know issues that these rays cause include Cataracts, Pterygium and Macular Degneration (the leading cause of blindness in older people), Corneal Sunburn and Skin Cancer around the eye. Let’s take a closer look at these so you know exactly what you are in danger of.
Pterygium is a growth that starts on the white of the eye and can grow into the cornea. This growth can eventually block vision. This condition is seen more regularly on people who work outside and see consistent exposure.
Macular Degeneration is a condition where the small central portion of the retina, known as the macula, deteriorates and because of this the inside back layer of the eye that records the images we see and sends them via the optic nerve from the eye to the brain cannot function. Exposure to the sun is a known contributor to this condition.
Cataracts are a clouding of the eye. The cells within the lens of the eye contain mostly water and some proteins but do not have the organelles usually found in other cells. Because of this the cells in the lens are transparent and thus uniquely capable of transmitting light and focusing it on the retina at the back of the eye. With a cataract forming you have the proteins inside lens cells start to show signs of oxidative damage and because of this they become clumped together, scattering light rather than transmitting it. A new study by the National Eye Institute about Cataracts and sun damage have documented a direct link to the damage UV Rays do to the eyes and how that damage causes cataracts.
The eyelids are actually very vulnerable to sun damage by the nature of the skin and even more so because very few of us actually put sun screen on our eyelids. Polarized sunglasses will help protect your eyelids.
Photokeratitis or in more laymen terms corneal sunburn can happen with even short term exposure to UV-B rays, in these cases it is usually just painful and will cause redness of the eye. According to Prevent Blindness extreme amounts of exposure can cause a temporary loss of vision and be extremely painful.
