Why Should We Wear Sunglasses?
The benefit of sunglasses
If you have ever been to the opticians, you probably know and have been told that it is important to wear sunglasses and protect your eyes. Almost every pair of sunglasses out there now have at least UV protection on them and it very important to make sure that they do. Furthermore, there are numerous choices now available for sunglasses, differing in styles and designs; the features of which have come a long way to make them cosmetically more appealing as well as comfortable and affordable. However, there are numerous other reasons why wearing sunglasses is important.
A major important factor to wearing sunglasses is to protect your eyes from UV-A and UV-B rays. UV rays can cause damage to the retina and cornea of the eye. The UV damage can create problems such as macular degeneration and cataracts. A few other lesser known problems that are caused by UV damage are photokeratitis which is a very painful eye condition and snow blindness which is caused by reflected/ glare from light colour or shiny surfaces, this causes the retina to be burned. Also, skin cancer has been found around the eyes, due to extended exposure to the sun without sunglasses. Just as the sun is damaging to your skin because of the UV rays, your eyes are just as susceptible to similar problems. Sunglasses with UV protection should give a 97% to 100% coverage from these rays. Remember, that dark sunglasses do not necessarily mean that there is UV protection, the sunglasses should have that right on the label.
Also, if your eyes are protected during the day from UV rays, you will also have better vision at night. Since your eyes have not been overexposed during the day, it makes night activities easier and your vision clearer. This is also true when it comes to driving or playing outdoor sports and wearing sunglasses. Eliminating glare and brightness will make any activity much easier. This includes a day at the park or walking about an outdoor shopping centre, wearing sunglasses will allow your eyes to adjust more easily when going indoors from outdoors.
Also, remember that just because it is a cloudy day, does not mean that sunglasses are not needed. Even on cloudy days, the UV-A and UV-B rays come through the clouds. In some instances, these rays are even stronger on cloudy days, because they have to make their way through the clouds to see the sunshine. Sunglasses are just as important on these days as well.
