Blueless blue light blocking glasses are crafted with sleek, modern designs to allow you to choose your own style! In addition to unparalleled durability, the frame also provides the most comfortable wearing today. Special semi rimless design for prescription glasses, more comfortable than clip-on sunglasses. CARE To avoid damage, never clean your reading glasses with paper towels or clothing or alcohol and also avoid using household detergents or soaps. While a few mild soaps don't harm lenses, today's extra strength soaps are powerful enough to slowly disintegrate lens coatings.
