Chosen carefully with an eye on practicality, functionality, and style, eyeglasses are a significant financial investment that keep your eyes healthy and your vision clear. Keeping glasses in tip-top, scratch-free condition as long as possible requires a commitment to proper handling and daily care. Even if your eyeglasses have a scratch-resistant coating, they are still susceptible to scratches and minor dings that are not only annoying, but can significantly affect your vision.
Rinse eyeglasses with lukewarm water before cleaning. Rinsing removes any microscopic dust that may scratch when you wipe the lenses.
Clean eyeglasses with a spray lens cleaner. If you don't have cleaner made specifically for eyeglasses, use a drop of liquid dish detergent or a gentle, abrasive-free liquid hand soap. If you opt for using soap, rinse glasses thoroughly with lukewarm water after washing. Avoid using window cleaner, vinegar, ammonia, or spit.
Wipe eyeglasses with a clean, soft, lint-free cloth or a microfiber cloth made specifically for glasses. Remember to wash the cloth regularly and store it in a protective case. Avoid using tissues, paper towels, or toilet paper. Never wipe glasses with your sleeve or shirt.
Store eyeglasses in a hard case when they are not in use. Use a properly fitting case that holds the eyeglasses securely, without rubbing or sliding. Don't place unprotected glasses in a shirt or pants pocket, purse, or handbag, as this is a sure way to damage the frame.
Set eyeglasses down carefully with the lenses facing up. Otherwise, open the glasses and place them with the top rim facing down. To prevent scratches, never place eyeglasses with the lenses facing down on a desk, table, or other hard surface.
Avoid high temperatures and direct sunlight. Never leave eyeglasses in a hot car, even in a protective case. Extreme heat may cause scratch-resistant or anti-reflective lenses to expand unevenly, which can result in cracks and warping.
