The Redefining Eye Protection Glasses offer optimal protection from harmful radiation of the sun, eyestrain-causing electromagnetic interference (EMI) and sleep-depriving blue light radiation emitted by digital device screens. Gauss glasses can be worn outdoors like regular sunglasses, indoors and even when driving at night. The breakthrough is made possible by combining a proprietary Blueguard coating with photochromic, high index lenses that block EMI, UV/A and UV/B while automatically changing their color and opacity from 10-75%.
