Sunglasses are adorn to secure your delicate eyes from numerous harmful effects such as dust particles, harmful radiations from sun, lightning from oncoming traffics at night and many other hazardous effects. However, sunglasses eliminates the glare and helpful to sustain the vision better.
Why should we use sunglasses?
- Ultra Violet rays protector- UV lights damages the cornea and the retina. Sunglasses effectively remove UV rays completely and secure your eyes from bad radiations.
- Sunglasses provide protection from acute light-
When the eye receives too much light, it naturally closes the iris. Once it has closed the iris as far as it can, the next step is squinting. If there is still too much light, as there can be when sunlight is reflecting off of snow, the result is damage to the retina. Good sunglasses can block light entering the eyes by as much as 97 percent.
- Sunglasses bestow protection from glare-
Certain surfaces, such as water, can reflect a great deal of light, and the bright spots can be distracting or can hide objects. Good sunglasses can completely eliminate this kind of glare using polarization.
