How Sunglasses Protect Our Eyes?

When it is a sunny day outside and you have a day off and want to go to the beach and have fun with your friends, what you do is take your bathing suit, some fine clothes and a pair of sunglasses. You always take your sunglasses almost instinctively because not only you will look good with a pair of trendy sunglasses, but also you know that you will feel good and it is more likely to enjoy the summer day with a pair of protective sunglasses. What we probably know about them is that they are keeping our eyes protected while we are enjoying the sun. It is now more comfortable to play volleyball on the beach or even reading a book or working on your computer. Nowadays we use sunglasses to feel more comfortable, but do we actually know how these sunglasses really work? Is there a specific technology that we don't know about and can we trust our sunglasses completely? We will try to give you these answers in this article.

It is not a mystery how sunglasses actually work. The scheme is quite simple sunglasses are actually two darkened lenses in a modern frame that can make you look fabulous. But how do these darkened lenses protect your eyes? They actually provide protection from the harmful UV rays. These UV rays can harm your eyes' retina and cornea. If the sunglasses you have chosen are good, you can be sure that the lenses will block all the harmful UV rays. If the sunglasses you have chosen are cheap and unreliable, you can see that their lenses are blocking some light and this way you keep your eyes open, but if the lenses are not blocking all the UV rays, you can feel the comfort to keep your eyes open but this way you are exposing them to the harmful sun rays and your cheap sunglasses can do more damage than protection.

There are different protective lenses. Some of them protect also from reflections. When the sun light reflects the snow or the sea water for example it makes reflections and this reflection can cause distractions of your sight. Expensive polarized sunglasses provide a hundred percent protection from glare.

There are also many different protections that a pair of sunglasses can provide such as protection from intense lights. Intense lights can be very harmful for our eyes because they cause our iris to close. But the iris cannot close completely and we start squinting instinctively. But if the light is still too strong and it is entering our eyes, the retina is starting to get damaged. If the retina is damaged, this may cause permanent vision problems. Good sunglasses can minimize that risk of light entering the eyes to 97 percent and this way to minimize the risk of getting you vision problems.

Good sunglasses also have protection from light frequencies. They can be very dangerous if we are practicing sports like skiing, fishing, snowboarding, jet skiing etc.
