Presbyopia glasses with blue light filter 25%. They are made of thermoplastic injected in the front and temples, which favors its adaptation to the face. The frame is classic and with marbled shades in gray and different browns. The blue light filter helps prevent potential damage from blue-violet light, a type of ray that emits enough energy to cause fatigue, visual stress and age-related macular degeneration. The lenses are non-prescription and feature scratch protection.
