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

Longitudinal chromic aberration as a function of refractive error
TL;DR: In this paper, the refractive error-dependence of longitudinal chromatic aberration was investigated, the hypothesis is being that myopia may be the outcome of inadequate cues to defocus.

Chromatic properties of astigmatic eyes
Tanya Evans,William F. Harris +1 more
TL;DR: In this paper, the dependence of the chromatic properties on the position of an object and the limiting aperture is explored and results are presented as independent of, or dependent on, object and aperture position.

Effect of Spherical Aberration on the Color Appearance of Small Red Dot
TL;DR: In this article, a small red dot surrounded by a black ring and white background appeared to be whitish through the adaptive optics (AO) system to produce spherical aberration on the 4 mm pupil eye.

Individualized modeling for the peripheral optics of the human myopic eye.
TL;DR: In this paper , a crystalline lens model was built to help reproduce the peripheral optical quality of the eye, which was then used to predict the individual peripheral optic quality over the central 40 degrees.

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.
