Quality Protection from UV Rays

It's safe to assume that almost everybody is exposed to UV rays on a regular basis. Even though this is the case, the risks related to years of exposure to these unsafe rays aren't really thought through, and most people take little action to shield their eyes, even if they're planning to be out in the sun for many hours. Being exposed to too much UV is unsafe and cannot be reversed, and may also result in a number of severe, sight-stealing diseases later on in life. And so, continuing protection from these rays is equally important for everybody.

UV radiation, originating mostly from the sun, is made up of 2 sorts of harmful rays: UV-A and UV-B. Despite the fact that only tiny amounts of UVA and UVB light hit the inner eye, the ocular cells are very susceptible to the dangerous effects of their rays. Intense, short-term of exposure may lead to sunburnt eyes, or photokeratitis. When the cornea receives UVB rays, the cells that make up its exterior are severely damaged, which can lead to pain, blurred vision or in serious cases, temporary blindness. UVA rays can actually penetrate much deeper into the eye, which causes damage to the retina. Of the 20 million people suffering from cataracts, an estimated 20 percent are due to extended UV exposure.

An ideal way to guard your eyes from UV rays is with good sunglasses. Ensure that your sunglasses or prescription eyewear block both UVA and UVB rays completely. An insufficient pair of sunglasses can be even worse than having no sunglasses at all. Basically, if your sunglasses offer no UV protection, you're actually increasing your exposure to UV rays. Sunglasses that are inadequate will reduce the light, forcing the iris to open and allow more light in. And this means that even more UV will reach the retina. It's important to check that your sunglasses offer maximum UV protection.
A large sunhat or cap can also block about fifty percent of UV rays. These hats may also limit UV rays that reach the eyes from above or around glasses.

Make an appointment to speak with your optometrist about all the different UV protection options, including, but not limited to, fixed tint sunglasses, adaptive lenses and polarized lenses.
