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.
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.
Hard Coating : can protect the uncoated lenses from scratch resistance .
AR Coating : also called hard multi coated , can protect the lens effectively from reflection, enhance functional and charity of your vision .
Super Hydrophobic Coating : also called crizal coating , can make the lenses waterproof, antistatic, anti slip and oil resistance. Generally speaking , super hydrophobic coating can exist 6~12 months.
