Pupil size shown to affect UCVA in astigmatic eyes
2012年2月7日 · UCVA was better in eyes with smaller pupil sizes and less astigmatism. The authors say smaller pupil size may have some advantages in image formation, such as an increasing depth of focus, a decrease in HOAs, and a decrease in light scatter, all of which may offset the deleterious effects of reduced luminance and diffraction and thereby ...
