Adjustable clear safety glasses. These glasses protect your eyeballs from little bits of glass, which can attack when you least expect it. You needn't be grinding up a storm to be hit with minute airborne particles -- simply stacking glass or breaking out a score can result in tiny shards flying at you. These fully adjustable glasses are lightweight, comfortable and stylish, unlike those big old goggles that you might have purchased but never wear. One-piece polycarbonate lens with integral sideshields, they even filter out 99.9 percent of UV radiation, so you can use them for outdoor activities as well.
