1. Good lenses, material is the key

 The material of a pair of lenses plays a decisive role in the light transmittance, durability and Abbe number (visual

effect of the rainbow pattern on the surface of the lens) of the lens. In-depth research and development can be carried

out on materials, with controllable quality and excellent performance.

2. The film layer makes the lens easy to wear

A good lens film layer can give the lens more excellent performance, not only the optical properties such as light

transmittance are greatly improved, and its hardness, abrasion resistance, and durability will be greatly improved.
