What Is Free form surface interior asymptotic？

The optical accuracy reaches the ideal optical accuracy. Crosswindows mold making, low channel astigmatism, low blind area, softer aberration area, and small deformation around the lens; The problem of limited vision has been significantly improved, and the time of initial adaptation is very short, which can be quickly adapted;

To meet the personalized needs, the lenses are customized according to different people;

Progressive lens refers to the gradual transition between the upper and lower focal lengths by using grinding technology;

The progressive multifocal lenses produced by Comeda Optics using the processing equipment of Germany Schneider garage.

The wearer does not need to remove the glasses when observing distant and near objects. Besides, moving the line of sight between the upper and lower focal lengths is also progressive. There is no sense of fatigue that the eyeball must constantly adjust the focal length when using dual focal lengths, and there is no obvious dividing line between the two focal lengths.
