1. Zeiss' patented "freetorus" lens manufacturing technology combines the center position of the eye axis with different luminosity and uses 700 free parameters to optimize the point-to-point lens design, showing personalized visual advantages and seeing more clearly. Using free-form surfaces for the first time on an off-the-shelf lens, the lens is thinner and flatter, and features intelligent distance optimization and edge optimization. Zerui is equipped with a full range of Zeiss diamond cube films. 2. Wide-angle view: clearer. Compared with ordinary aspheric lenses, the clear field of view of the lens is expanded by an average of 3 times. Compared with aspheric lenses, our clear field of view is expanded, the clear field of view is expanded, and the peripheral deformation caused by the lens can also be reduced. Especially suitable for users who like a clear and comprehensive view. 3. Flatter and thinner: Compared with ordinary lenses, the average thickness is reduced by 8% and the flatness is improved by 32%. Compared with Zeiss' ordinary aspherical design under the same refraction parameters, it is flatter and thinner, and can be matched with more types of frames, making it very suitable for users who pursue comfort and beauty. You can also choose a larger frame for a smaller face! !
