Spy's Happy Lens technology allows the "Good" long-wave blue light rays in, while blocking the "Bad" UV Rays and short-wave blue light rays.
Long-wave blue light promotes balance in the body which in return gives you a positive uplift in your mood and alertness.
The lens is a polarized and color contrast-enhancing lens, giving you the best visual experience possible.
