For eyeglass/sunglass lenses

Coatings for eyeglass and sunglass lenses

Eyeglasses and sunglasses are made with plastic lenses.
The main issue is that these are very susceptible to scratches.
Hard coatings help to protect these fragile surfaces.

Hard coatings create a glass-like layer on the surface, which greatly enhances scratch resistance.
