If you're talking nearsightedness, if you're under corrected by a 1/4 diopter your far point is at 4 meters, the additional correction would push you out to infinity. It may be noticeable at night. It depends on how high your correction is to begin with. A 1/4 D change would be more noticeable to someone who's only a -.25 to begin with vs someone who's already a -12.
Negligible change in spherical equivalent, you have to take into account the change in astigmatism. Unlikely to be noticeable.Quote:
