When smudges or streaks appear on your glasses, grab some type of cloth to wipe them away %u2013 but don%u2019t use any old napkin or tissue that might be lying around. Rough materials can scratch the anti-reflective coating. Choose a microfiber cloth designed specifically for glasses to ensure that you don%u2019t ruin the coating. No matter what type of cloth you use to clean your glasses, do not wipe them when they're dry. Without lubrication, dirt or debris on the surface of the lenses or in the cloth can scratch your glasses. Wet your lenses with warm water before wiping them with a microfiber cloth. For stubborn smudges or dirt, use a cleanser specifically for eyeglasses or a mild liquid soap. Avoid harsh products, such as window cleaner, bleach, alcohol, ammonia or even vinegar, which can damage the anti-reflective coating. Rinse the lenses with warm water before drying with a clean, dry microfiber cloth. Pre-moistened lens-cleaning cloths work well when you%u2019re on the go.
