Can you use cotton for glasses?
Don't reach for your T-shirt, either. Very few cloths are safe for cleaning eyeglasses. Even soft-seeming materials, such as your favorite tee, can cause microscopic damage that ruins lenses over time. Microfiber cloths are your best bet for effective and damage-free cleaning and drying.
What fabric won't scratch glasses?
Microfiber is comprised of small nylon and polyester fibers that are designed to prevent scratches. Just be sure to use a microfiber cloth in conjunction with water or an eyeglass spray. If particles are present on your lenses, even microfiber cloths will grind them into the surface.
Is it OK to wipe glasses with shirt?
While these habits may seem harmless, they don't actually “clean” your glasses and ultimately can end up damaging your frames. Don't use your shirt (or clothing in general) to clean your glasses. The dust and debris on fabrics can scratch your lenses. Don't use paper towels or tissues to clean your glasses.
Do glasses scratch easily?
Most glasses are pretty scratch-resistant already. To help keep the lenses this way, the most basic step is to keep them in a case when they are not in use and use a microfiber scratch-free cloth for cleaning. The best way to clean them is to use non-moisturizing liquid hand soap or dishwashing detergent.
