How Spy Happy Lens Work

Sunlight is composed of both good rays and bad rays. Short-wave blue light and UV (ultra violet) rays are harmful for our eyes; the bad rays. Studies suggest that long-wave blue light is beneficial when it enters our eyes; the good rays. The first of its kind, the Spy Happy Lens is designed to let in long-wave blue light. So it blocks the bad rays and lets in the good rays. Long-wave blue light promotes balance in the body's circadian rhythm, fostering a positive "uplift" in mood and alertness. There's more! Happy lens can be polarized and it has unmatched color-contrast-enhancing lens.
