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.
