Visual benefit of correcting the higher order monochromatic aberrations and the chromatic aberration in the eye

摘要

We demonstrate increases in contrast sensitivity and letter acuity in white light and in monochromatic light when adaptive optics corrects the eye's higher order monochromatic aberrations. The contrast sensitivity and visual acuity when correcting most monochromatic aberrations with a deformable mirror are higher than when defocus and astigmatism alone are corrected. Moreover, correcting both monochromatic and chromatic aberrations provides an even larger increase in contrast sensitivity and visual acuity. These results are in good agreement with the theoretical visual benefit from the optical modulation transfer function based on the measured eye's aberration with a Hartmann-Shack wavefront sensor.
