Scratch resistant coating for your eyeglasses is one of the best investments you can make in your vision care. Cleaning the eyeglass lens with scratchy material or dropping your eyeglasses on the ground can cause an unsightly permanent scratch on the lens that can impair clear vision. By opting for scratch resistant lenses when ordering a new pair of eyeglasses or sunglasses, the wearer dramatically reduces the possibility that one or both lenses will be damaged by scratching.
Most lenses used in eyeglasses today feature materials that have already built in a scratch resistant coating. But it is important not to assume that the lenses being used in the eyeglasses you are ordering automatically feature scratch resistant lenses. Ask your optician if scratch resistant coating is an option on the type of eyeglasses you are purchasing. By asking for this added feature for your eyeglasses, you have peace of mind that the lens surface will have an added measure of durability against accidental scratching.
Unfortunately, once a pair of eyeglasses is already scratched, adding a layer of coating will not remove the existing scratches. If the scratches are numerous or large enough to interfere with clear vision, you may want to consider replacing the damaged lenses with scratch resistant lenses.
No coating added to eyeglass lenses can make them 100% scratchproof, so it is important to treat eyeglass lenses treated with a resistant coating with special care. When not wearing your eyeglasses, store them in a case with a soft interior and keep this away from pets and children. Ask your optician for advice about cleaning cloths such as microfiber cloth which won't scratch the lens during the cleaning process unlike tissues or paper towels which can be abrasive. Your optician can also suggest the proper cleaning solutions for cleaning lenses to help avoid problems with scratching the surface of the lens.
