Features of 1.499 Single Vision Lens

It is the first generation of lighter, impact-resistant resin lenses. The refractive index is close to that of glass, the specific gravity is 1.32 (almost half of glass), and the Abbe number is 58~59, which is the highest Abbe number in all resin lenses. This means little dispersion, high light transmittance, impact resistance, and the ability to tint and coat.

What Is the Difference Between HC, HMC and SHMC?

• HC: Hard coating has both toughness and hardness by using a hardening solution containing organic matrix and inorganic superparticles including silicon elements, Improve the wear resistance of the lens.

• HMC: Multicoated is done after hard coating, It is mainly an anti-reflection coating, which can increase the visible light transmittance of the lens and prevent ultraviolet and radiation.

• SHMC: Hydrophobic coating can reduce the contact area of water and oil with the lens, so that the oil and water droplets are not easy to adhere to the surface of the lens, so it is also called waterproof coating and super HMC.
