Features:
1.56 middle index lenses are one of the most popular lenses all over the world. This determines that Aogang 1.56 single vision lenses have the most outstanding optical features:
1. Thickness: In the same diopters, 1.56 lenses will be thinner than CR39 1.499 lenses. As the increase in diopters , the difference will be bigger.
2. Visual Effect: Compared with high index lenses, 1.56 lenses have higher ABBE value, can provide the more comfortable visual experience.
3. Coating: The uncoated lenses are easily subjicted and exposed to scratches, hard coating lenses can effectly scratch resistance.
UV Value
UV400 means one hundred percent anti-ultraviolet.
UV is the wavelength of 200nm ~ 380nm from the sun light, including three categories: UVA wavelength of 315nm ~ 380nm, UVB wavelength of 280nm ~ 315nm, UVC wavelength of 200nm ~ 280nm.
UV-400: Optical lens with "UV-400" can block all the UV, can be 100% reflection, absorption of ultraviolet light.
Coating
What makes Hydrophobic lenses special?
SUPER HYDROPHOBIC will keep lenses cleaner longer because of the added benefit of anti-fog and anti-static additives. A lens pulled through steam in a regular ant-fog test will dissipate fogging up within 8 seconds while a untreated A-R coated lens will take up to 52 seconds to clear up.

How the SHMC work?
Anti-reflective coating is a microscopically thin multi-layer coating that eliminates reflections from the front and back surface of eyeglass lenses. No glasses have anti scratch but lenses that are treated front and back with a clear, scratch-resistant coating have a much harder surface that is more resistant to scratching, whether from dropping your glasses on the floor or occasionally cleaning them with a paper towel. |
