We’re all guilty of quickly rubbing our glasses on our shirts or using a paper towel to clean the lenses. While these habits may seem harmless, they ultimately can end up damaging your frames.

1. Don’t use your shirt (or clothing in general) to clean your glasses. The dust and debris on fabrics can scratch your lenses.

2. Don’t use paper towels or tissues to clean your glasses. These materials are too rough for your lenses and can cause small scratches. Dish towels or other fabrics that can trap dust and debris may also scratch the lenses.

3. Avoid using household cleaning products to clean your lenses. Cleaning products usually contain harsh ammonia-based chemicals that can destroy the protective coating on your lenses.

4. Don’t leave your glasses out on the bathroom counter when getting ready. Hairspray and beauty products can get on your lenses and damage the protective coating.

5. Never try to buff out a scratch. Attempting to buff your lenses will only result in more scratches and damage. Take your glasses to a professional if you have a scratch that you need to be removed.

6. Don’t leave your glasses in the car on a hot or cold day. Extreme heat or cold can damage lens coatings and also may change the frame shape.
