The refraction of the eye in the relation to spherical aberration and pupil size.

摘要: Available theoretical and experimental data on the dependence of subjective refraction eye spherical aberration pupil size are reviewed additional results presented. Under photopic conditions, varies little (similar to 0.3 DS) with diameter, even when substantial amounts present 1.0 DS). It is argued that this result may be attributed insensitivity optimal focus at spatial frequencies involved in refraction, Stiles-Crawford effect influence aberrations other than primary outer zones pupil. The signficance these findings indicated relation possible discrepancies between objective refractions large pupils use.
