Understanding blue light
High-energy visible light is high-frequency, high-energy light in the violet/blue band from 400 to 450 nm in the visible spectrum, which has a number of biological effects, including those on the eye. Our glasses help block up to 99.9% to 100% of blue/UV light to prevent damage to your eyes.
Be good to your eyes
Built to last
