Our High Definition, near clear, lenses offer everyday protection against damaging blue light. Blue light (HEV Light) is the most damaging part of the light spectrum & can reach deeper into the eye than UV (ultraviolet) light. Emerging research has linked Blue Light to long-term vision issues, Macular Degeneration, Cataracts, Retina Damage, and even blindness. Light emitted from LED lighting & electronic devices (smart phones, tablets, TV’s computers) are “short wavelength enriched”, meaning they have a higher concentration of Blue light. ESP High-Definition lenses have been designed to filter the harmful portions of blue light, while significantly reducing glare & enhancing contrast.
