√By using the new technology of optical thin film and vacuum, a certain thickness of single-layer or multi-layer optical thin film is plated.

√So that the lens can obtain some new and original excellent properties, so as to improve the ability of reflecting light.

√It can enhance or reduce the light transmission and increase the light transmittance of the lens to more than 98%.

√Hard film: increase the hardness of the lens surface, making it more wear-resistant.

√Antireflection film: increase the transmittance of the visible light of the lens and the performance of anti ultraviolet and anti radiation.

√Antifouling film: make the lens surface more smooth and clean, increase the waterproof, antifogging, dustproof and other anti pollution functions.
