What You Need To Know About UV Rays

Virtually everyone is exposed to UV rays on a daily basis. Even though this is the case, the potential risks of years of exposure to these unsafe rays are rarely thought through, and most people barely take enough action to protect their eyes, even if they're expecting to be out in the sun for an extended period of time. Being exposed to too much UV is dangerous and irreversible, and may also cause several serious, sight-stealing diseases later on in life. Therefore, ongoing protection from UV rays is equally important for everybody.

UV radiation, which originates mostly from the sun, is made up of 2 sorts of harmful rays: UV-A and UV-B. Even though only small amounts of UVA and UVB light enter the inner eye, the eye tissue is very receptive to the damaging effects of their rays. Intense, short-term of exposure can easily result in sunburnt eyes, or photokeratitis. When the cornea receives UVB rays, the surrounding cells are destroyed, which can cause blurred vision, pain or temporary blindness. UVA rays can actually permeate the eye much deeper, which causes damage to the retina. After several years, UV rays can lead to substantial damage to the eyes.

An ideal way to shield your eyes from UV rays is with good eyewear. Ensure that your sunglasses or prescription glasses block 100 percent of UVA and UVB rays. An inadequate pair of sunglasses can sometimes be worse than having no sunglasses at all. Consider this: if your sunglasses don't give you any protection against UV, it means you're actually getting more UV rays. The inadequate sunglasses tend to reduce the light, forcing your iris to open and let even more light in. And this means that even more UV will hit the retina. It's important to check that your sunglasses offer maximum UV protection.

Speak to your optometrist about the various UV protection choices, which include adaptive lenses, polarized lenses and fixed tint sunglasses.
