TLDR
The reduced eye was further modified by changing the refracting surface to an aspherical shape to reduce the amount of spherical aberration, providing an improved account of both the longitudinal and transverse forms of ocular chromatic aberration.Abstract:
New measurements of the chromatic difference of focus of the human eye were obtained with a two-color, vernier-alignment technique. The results were used to redefine the variation of refractive index of the reduced eye over the visible spectrum. The reduced eye was further modified by changing the refracting surface to an aspherical shape to reduce the amount of spherical aberration. The resulting chromatic-eye model provides an improved account of both the longitudinal and transverse forms of ocular chromatic aberration.read more

Ray tracing in the human eye: measurement and modeling of optical aberrations
TL;DR: In this article, the authors present the work carried out by their group to develop methods for measuring and modeling the optical performance of the eye, which are applied to design both custom surgery and optical aids to improve optical performance.

Eye tracking-based estimation and compensation of chromatic offsets for multi-wavelength retinal microstimulation with foveal cone precision
TL;DR: The solution enables continuous correction of TCO with high spatial precision and avoids high light intensities required for re-measuring TCO after eye position changes, which is necessary for foveal cone-targeted psychophysical experimentation.

Theoretical influence of Stiles-Crawford effect on vision with decentered pupils
TL;DR: The Stiles-Crawford effect appears to reduce subjectively measured transverse aberrations for 5mm diameter pupils by approximately one-third as mentioned in this paper, which may compensate to a small extent for pupil decentration.

The Frequency Response of a Defocused Optical System
TL;DR: In this paper, the response of a defocused aberration-free optical system to line-frequencies in the object is studied analytically, and curves are given showing the response as a function of line-frequency for a range of values of defect of focus.

Saccadic eye movements towards stimuli triggered by prior saccades.
P.E. Hallett,A.D. Lightstone +1 more
TL;DR: The only finding reminiscent of perceptual “saccadic suppression” and mislocation effects is that a target which steps to a position ahead of a saccade is sometimes ignored.
Journal ArticleDOI
Theory and measurement of ocular chromatic aberration.
TL;DR: One implication of these results is that, although the eye has substantial chromatic aberration, the pupil is positioned so as to minimize the transverse component of the aberration for central vision, thereby optimizing foveal image quality for polychromatic objects.

The change in refractive power of the human eye in dim and bright light.
George Wald,Donald R. Griffin +1 more
TL;DR: It is concluded that setting optical instruments about 0.4 diopter more negatively in dim than in bright light is justified on the basis of the chromatic aberration of the eye.
