Finally a high end blue filter BIFOCAL lens, VERY hard to find, with excellent properties to filter blue and UV light, as well as help reduce bright light induced insomnia. These are lined bifocal lenses and feature high end optical cr90 material, clear no power on top with the power located on the bottom. Classic rectangular eyeglass frame, incredible colors, and high quality tr90 flexible yet resilient plastic.
These DO have a slight to moderate amber tint which is important to promote a healthy sleep cycle. 99% UV and 32% blue light filtration. Since this is a brand new product, some of the photos posted may depict clear lenses, but the actual product has amber tint lenses. Photos will be updated soon to reflect the amber tint.
