Some people buy sunglasses name brand or not, hoping they will look like a movie star or just improve their appearance. Some others will buy dark glasses to hide their identity or at least their eyes. Some others just love to shop and buy them for fun, while most others buy great sunglasses to protect their eyes in the sunlight.
Most sunglass makers are making the decision even harder with the new styles adding the lense coatings that are supposed to make their sunglasses the best ones for your eyes protection. These decisions can be difficult to make because most places that sell sunglasses are indoors and testing the glasses in the sun light is almost impossible.

Eye doctors will tell you that you do not need to wear sunglasses every time you go outside since the suns uv rays are not always strong enough to do damage and your eyes have a built in defense. Your cornea will block your eyes from most of the harmful uv rays from the sun, and if damage does occur the cornea will repair most of this damage really quick. If you are exposed to alot of the suns light and glare from snow or other really intense conditions for long periods of time, you can experience pain from the cornea being overwhelmed with too much too long. Even at this extreme your cornea will repair itself in a few days and the pain will subside. Your cornea does not work alone the lens sits behind the pupil and will help to stop the rays from entering the retina, which is very sensitive to sun light.
