Everyone is regularly exposed to UV rays. Even though this is the case, the possible dangers related to years of exposure to these harsh rays are rarely thought about, to a point where the majority of people barely take enough action to protect their eyes, even when they're planning on being exposed to the sun for long periods of time. Overexposure to UV is unsafe and irreversible, and may also result in several serious, sight-damaging diseases in older age. This means that ongoing protection from UV rays is equally important for everybody.
UV radiation, which originates mostly from the sun, consists of 2 types of damaging rays: UVA and UVB. Despite the fact that only small amounts of UVA and UVB light enter the inner eye, the ocular tissue is extremely susceptible to the harmful effects of their rays. Small amounts of this kind of exposure can lead to sunburn of the eye, often referred to as photokeratitis. When the cornea receives UVB rays, the outer cells are destroyed, which can be expressed as pain, blurred vision or even temporary blindness. UVA rays can actually permeate the eye much deeper, which harms to the retina. Over time, not being protected from UV rays may be responsible for substantial damage to eye sight.
One of the best ways to protect your eyes from UV rays is with good sunglasses. Ensure that your sunglasses or prescription glasses block 100 percent of UVA and UVB rays. An inadequate pair of sunglasses can be even worse than having no sunglasses at all. Consider this: if your sunglasses don't give you any UV protection, you are actually being exposed to more UV rays. The inadequate sunglasses tend to reduce the light, causing your iris to open and let even more light in. And this means that more UV will hit your retina. Always check to make sure your sunglasses offer effective protection against UV.
Talk to your eye care professional about the various UV protection options, which include adaptive lenses, polarized lenses and fixed tint sunglasses.
