SPY HAPPY LENS Technology
With a patent-pending on its therapeutic qualities, the Happy Lens was designed to maximize the transmission of the sun's good '' rays while still blocking out its bad '' rays. The good '' rays are a specific type of long-wave blue light. Exposure to the good '' rays has been shown to help align the human body's rhythm with its natural preference for specific color and wavelengths, fostering positive changes that can help harmonize Spy's body. Happy Lens is a color and contrast enhancing lens that makes bluebird days bluer, and bumps and jumps more distinct. So you can enjoy nature's awe-inspiring beauty in ways you've never seen or felt before. See Better. Feel Better. Perform Better.
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.
