Perkins brings an air of retro cool to reading and other tasks. These reading glasses have a classic browline frame made of satin dark gunmetal with matte rubberized black brows and tips. Adjustable nose pads and spring hinges offer you all-day comfort and security. This pair of glasses comes with the case pictured for easy storage and protection. Get just the pop of magnification you need to read with Pop of Power® reading glasses. Each lens features a magnified reader segment at the bottom; the rest of the lens is unmagnified. And the whole lens helps to filter 30% of potentially harmful blue-violet light* produced by computers and other devices. So, you can keep your glasses on”and your vision clear”when you shift between reading and looking up to see across the room or interact with others.
