Prescription sunglasses are regarded by many as an absolute necessity, especially for those who wear prescription glasses all day. You see what most people don’t realise is that even on the coldest day, when the sky is even slightly overcast, the Suns UV rays will find a way to penetrate your eyes. The effects of theses harmful rays can sometimes lead to permanent damage of the front tissue or, in some severe cases, the retina. The suns UVA and UVB rays are also known to cause ‘photokeratitis’ , which is a common eye condition that can cause temporary extreme light sensitivity, or in some cases, severe inflammation of the cornea. This condition normally happens when you go outside on a very cold, but extremely bright and dazzling day. ‘Pterygium’ is another serious condition that can happen when the eyes are left unprotected. Pterygium is a non-cancerous growth on the cornea of the eye which can only be removed by surgery. One of the biggest problems with UV radiation is that, on a very bright day, it will reflect off of snow, pavements and other surfaces. Obviously, wearing a pair of prescription sunglasses would protect you from the dangers of this condition as they would filter out any harmful rays through the lenses.
But why would anyone actually want to go out without any eye protection. After all, you wouldn’t venture outside on the sunniest day of the year without any skin UV protection would you? Not wearing a pair of prescription sunglasses carries the same dangers as going out without a UV skin blocker. On a bright summer’s day, when the suns UV levels are at their highest, the UV rays can quickly penetrate and start to burn the surface of your eyes. Being exposed to these rays for a long period of time can lead to the retina being permanently damaged. There are also hundreds of cases per year where people, who have not worn sunglasses over a prolonged period, have been diagnosed with very early signs of cataract, and in the worst case scenario, skin cancer around the eye lids. So you see, all in all the benefits far outweigh the cons of wearing eye protection all year round.
