Powerful resistance to scratching

The main concern of customers in terms of the performance of eyeglass lenses is resistance to scratching. Surfaces of the lens have been hardened and their resistance to scratching has been improved. SRC2 UVP-BR and SRC2 UVP have the greatest capability of scratch-resistance.

〈Bayer Test〉

*Bayer test: Lens is scratched in about 200 grams of sand with 800 times vibrations. The degree of opacity of the lens is then checked and determined.

〈Steel wool Test〉

*Steel wool test: Put a piece of steel wool between a lens and a test tube, apply 20 rounds of a 2-kilogram load, and then compare the degree of scratching.
