Although no lens material is “scratch-proof,” it’s important to protect your new lenses with a scratch-resistant treatment.
Lenses with the best scratch protection are treated on the front and backside with a clear, hard coating to be scratch resistant. Some lenses have built-in scratch resistance. However, it’s important to know that not all scratch resistant treatments are equal, and not all treatments protect both the front and back surface of the lens. A two-sided scratch resistant treatment provides the best protection.
Ask an optician for more information on the best treatment for your lenses.
