SPY is an unconventional, fun-loving family of athletes and artists committed to creating exceptional optical products. Established in 1994, they are an independent Southern California- based company. They 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. Their 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.
