For those who often get tired eyes from long hours of computer work or smartphone use, please give these a try. It is said that the blue light emitted by LED screens, such as those used for computer work, puts a significant strain on the eyes! The lenses are blue light cut (approximately 60% cut rate) and are brown-tinted. The frame is black♪ These glasses do not have prescription lenses. Material: Lens/Polycarbonate, Unisex Size: Height 30mm x Width 138mm x Depth 150mm I bought these new but have never used them and have been storing them at home. Only the item itself is included. They will be packaged with air cushioning for delivery.
