Interspecies comparison of optics. (A) RMS as a function of pupil size for mouse (Geng et al., 2011), tree shrew and human (Salmon and van de Pol, 2006). (B) Radially-averaged MTF for tree shrews (n = 11 eyes) and humans (n = 74 eyes (Cheng et al., 2004)) for a 4 mm pupil. Dotted lines indicate the spatial frequency cutoff and the corresponding contrast for each species. (C) Comparison of PSFs and cone spacing for tree shrew and human. D-L: diffraction-limited PSF; dashed lines: row-to-row separation for tree shrews (6.5 μm). Scale bar = 20 μm.
