SPY is an unconventional, fun-loving family of athletes and artists committed to creating exceptional optical products. Established in 1994, we are an independent Southern California- based company. We design products—sunglasses, goggles, and prescription frames—that take style cues from the outdoor sports community we’re engrained in, as well as the lifestyle that surrounds it. Our exclusive Happy Lens technology is the only lens on the market which harnesses the beneficial aspects of long-wave blue light, while offering protection from short-wave blue light known to damage the eyes. The Happy Lens name comes from independent studies which have shown that long-wave blue light can positively affect a person’s mood and alertness. We’ve taken the therapeutic and visual performance benefits of our patented Happy Lens and combined them with the superior clarity of digitally mastered High Definition lenses to create the next evolution in eyewear from SPY. Now you can enjoy enhanced color and contrast, improved mood and alertness, and impact resistant distortion-free optics in one awesome package. It’s probably the best lens ever.
