About lenses: ClearBlue computer glasses use magnetic lens technology to filter out dangerous UV and blue light rays. The lens quality is crystal clear, for exceptional color preservation and visual acuity. The wafer-thin hi index lens has excellent optics. Special AR coating is an added bonus to reduce glare from your computer or device. About 65% UV and over 50% of HEV blue lights are blocked.
