1）Product featurs: 1. Because of their ability to bend light more efficiently, high-index lenses for nearsightedness have thinner edges than lenses with the same prescription power that are made of conventional plastic material. 2.Thinner edges require less lens material, which reduces the overall weight of the lenses. Lenses made of high-index plastic are lighter than the same lenses made in conventional plastic, so they’re more comfortable to wear. 3.Aspheric design for less lens distortion.Great optical clarity and sharpness. 4.The 1.60 Acrylic series is not suitable for rimless glazing but MR-8 material is suitable for rimless glazing.We provide both 1.60 Acrylic and 1.60 MR-8 lenses.2） What is the difference between HC, HMC and SHC？

Hard coating	AR coating/Hard multi coating	Super hydrophobic coating
makes the uncoated lens hard and increases the abrasion resistance	increases the transmittance of the lens and reduces surface reflections	makes the lens waterproof, antistatic, anti slip and oil resistance
