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

Image quality in pseudophakic eyes with two different types of intraocular lenses ranging in the degree of high myopia
TL;DR: For chromatic and spherical aberrations and polychromatic MTF, the type of IOL that would best improve image quality for a given patient can be established.

Chromatic Aberration, Linear Models, and Matching Color Images.
TL;DR: The OTF calculated suggests an improved procedure for matching color images on emissive displays and introduces linear models for surface and illuminant spectral functions and shows how their use simplifies the prediction of photoreceptor responses.

Contrast adaptation appears independent of the longitudinal chromatic aberration of the human eye.
TL;DR: Contrast adaptation under mesopic illumination occurs independently of the longitudinal chromatic aberration of the eye; it can be inferred that this mechanism can be used to distinguish between the sign of optical defocus in poly- and monochromatic light conditions.

Optical Surface Optimization for the Correction of Presbyopia
TL;DR: The methodology described in this paper is designed to correct presbyopia by optimizing vision over the entire target range of near to distant by employing an iterative function minimization algorithm to optimize an optical metric.

Using wavefront measurements to predict visual acuity
TL;DR: In this paper, a resolution ring is constructed using Rayleigh's criterion for the determination of optical acuity, and subsequent cross correlation of the blurred resolution spoke with the un-blurred spoke is used to estimate decentration of the PSF.

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.

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.
