How to Identify the Scratch Coating on Eyeglass Lenses
- 1). Compare a pair of glasses that you suspect have scratch-resistant lenses to a pair of glasses that you know for a fact do not have them. Lenses that are scratch-resistant have a much harder surface than lenses that are not scratch-resistant. You should be able to tell by a visual inspection of the surface and the feel of the lenses.
- 2). Give the lenses a glare inspection. Even though not all lenses that are scratch-resistant are glare-resistant, many are. If you do not see a glare in them that could be a sign that they are scratch-resistant.
- 3). Look for scratches on the lenses. Pay attention to tiny scratches that look like hairs stuck to the lenses. Wash the lenses with warm water and a mild detergent. Rinse. Are the tiny scratches still there? If there are no scratches whatsoever on the lenses, it is a high probability that the lenses are scratch-resistant.
