Prison glasses are eyeglasses that are specially designed for inmates who need corrective lenses. They are usually made of plastic or metal frames with polycarbonate lenses that are shatter-resistant and scratch-resistant. They also have safety features such as hinges that break away easily and screws that do not protrude from the frame.
