Spy, founded in the mid 90's by a group of Design-Freaks has produced nice sunglasses for years. They are high in quality and worn by many athletes. This is the Discord Fade To Black, another great product.
Spy Optics have been keeping our eyes safe since 1994. Their eyewear is inspired by the action sports lifestyle and made to fit seamlessly into it. Keeping up with innovation, Spy have developed a technology which allows long-wave blue light to pass through their lenses, which is said to have a positive effect on a persons mood and alertness. They say good things come in small packages, and in this case that is a pair of Spy Optic sunglasses.
