Aviator sunglasses, also called 'pilots' glasses', were originally developed by Ray-Ban for pilots to protect their eyes while flying. They are characterized by dark, often reflective lenses with an area two or three times the area of the eye socket, and metal frames with bayonet earpieces or flexible cable temples that hook behind the ears. This kind of structure is designed to cover the entire range of the eye and prevent as much light as possible from entering the eye from an angle.
If you find your big sunglasses nowhere to put when you come indoors, folding aviator sunglasses is a wise choice which is convenient to keep. They can fold up to just the size of one lens and you can just put them in your pocket or keep them in your bag for unexpected sunny days. When unfolded, they look like the ordinary sunglasses and there is no difference in their function.
Another kind of best-rated aviator sunglasses is the mirrored aviator sunglasses. Many movies since the late 80's have been promoting mirrored aviators. They are sunglasses with a reflective optical coating (called a mirror coating or flash coating) on the outside of the lenses to make them appear like small mirrors. The mirror coating decreases the amount of light passing through the tinted lens by a further 10-60%, making it especially useful for conditions of sand, water and snow. These sunglasses, also known as mirror shades, are effective in protecting your eyes.
In television shows and movies, the main characters are easily found wearing the aviator sunglasses. They are becoming increasingly prevalent and will always be the everlasting products in the industry.
