Does pupil distance affect glasses greatly?

Pupil distance refers to the distance between the two pupil centers when the eyes are looking up. The normal pupil distance for men is about 60.9 mm, and the normal pupil distance for women is about 58.3 mm. Under normal circumstances, the pupil distance has little effect on glasses, and various pupil distances can be matched with glasses. But when glasses are matched, be sure to pay attention to the distance between the optical centers of the two glasses lenses, and be sure to match the pupil distance. If the alignment is inaccurate, prism effect will occur, and the light entering the eye will be scattered, causing eye fatigue and deformation when viewing objects.
