A scratch-resistant coating is also called a ‘hard coat’ or permagard. Plastic lenses are more susceptible to scratches than glass lenses and can occur from any type of contact — even just cleaning your lenses with the wrong type of cloth. A scratch on your eyeglass lens can impact your vision clarity and be quite irritating, especially if you only recently purchased your eyeglasses. When this coating is applied, the lens becomes harder and therefore more resistant to scratching.

Allows more light to reach your eyes, improving visual acuity.

Extends the life of your glasses lenses and saves your money.

Makes your eyes more visible behind your lenses, so your facial expressions are easier to see.

Makes lenses resistant to the scratches that are liable to occur through everyday usage.

Lenses with a scratch-resistant coating have a much harder surface that is more resistant to scratching, whether from dropping your glasses on the floor or occasionally cleaning them with a paper towel.
