If your kids work do school from home staring at a computer screen, or you find they spend too much time on your phone (as we all do) and worry it's starting to strain their eyes, these blue light blocking kids glasses are perfect for them! Blue light is the light that is emitted from televisions, computer screens, phone screens, and other displays. Blue light has been linked to possibly disturbing sleep patterns, mood regulation, eye health, and more. Help maybe improve your children's quality of life with these blue light glasses if they are a tech savvy person around screens all day long! The black glasses come packaged individually in hanging packs all in a countertop display sorted in 4 rows of 6 for 24 total pairs of glasses.
