The Elwood is a lightweight plastic reader with a classic frame shape that somehow also manages to look modern. It's a style that we all love. Your style is not boring why should your readers be? The blue light lenses help filter out the blue light emitted by phone, computer and tabled screens reducing the strain on your eyes without sacrificing style. These lenses are ultra-thin and scratch resistant, so you experience crisp optical clarity while wearing these glasses to read, whether it's a book, computer or menu.
