The Three Advantages of 1.74 ASP UV400 SHMC
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.

The spherical design was used to increase the aberration and deformation. As a result, the image was unclear, the field was distorted, and the field of view was narrow.
But the aspherical design corrects the image, solves the problem of distortion of the horizon, and makes the lens lighter, thinner and flatter. Moreover, it still maintains excellent impact resistance for safe wearer wear.
Our 1.74 index lens is made of Super Hydrophobic Coating , it's 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.
