Lightweight, scratch-proof, unbreakable eyeglass lenses

Lenses for eyeglasses are generally made of CR39 (a thermosetting plastic) or polycarbonate, both of which are light in weight and do not break easily. Despite their advantages, these materials are relatively soft and reflective. They only attain the desired characteristics after surface treatment and finishing through applications of nano-coatings. This creates a hard, anti-reflective, and dirt repellent surface.

Plasma nano-coatings create anti-fogging and scratch-proofing eyeglass lenses

Cost-efficient manufacture of high-end eyeglass lenses

The biggest challenge in manufacturing quality eyeglass lenses is mass producing them cost-efficiently. The manufacture of such lenses can be completely automated by combining low-pressure plasma processes (application of the scratch-proof layer) and Openair® Plasma processes (for anti-reflection and anti-fogging coatings) in one manufacturing line.
