Wavelength light of 500 nm or below, which causes glare and blurring of contrast, is light rays with high scattering rates and high levels of energy. The CCP absorption lenses developed by Tokai Optical are able to suppress 380 to 500 nm blue wavelength lights, which have major effects on the retina and cornea, and relieve discomfort from eye disorders that make people sense glare. In addition to being made of plastic and easy to handle, they are also available at affordable prices, so please be sure to give them a try.
Ordinary sunglasses not only filter light that causes glare, they also reduce the kind of light that gives a sense of brightness. It can make slightly darker areas in the field of vision too dark. Absorptive lenses permit selected wavelengths of light to reach as much as possible, providing greater brightness than conventional sunglasses of the same color and density.
