This powerful lens cloth is one of the best tools available for cleaning prescription eyeglasses, sunglasses, camera lenses and other optics. It quickly eliminates all dirt, dust and smudges without leaving behind lint, streaks, scratches or anything else. The premium quality material is super soft, and it cleans so well that you will even remove dirt and build-up that is invisible to the naked eye. The glass will be left clear and polished with no signs of the dust, dirt, grease, fingerprints. Stop using overpriced cloths and expensive sprays to clean your glasses, but don't take a risk by using something that might cause scratching and other damage. A dry cloth alone will remove almost anything in a matter of seconds, but for tough grime or thorough cleaning, get it damp with regular water to increase cleaning power. Each one is washable, reusable, and durable.
