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

Spatial visual function in anomalous trichromats: Is less more?
Ravid Doron,Anna Sterkin,Moshe Fried,Oren Yehezkel,Maria Lev,Michael Belkin,Mordechai Rosner,Arieh S. Solomon,Yossi Mandel,Uri Polat +9 more
TL;DR: It is shown here that anomalous trichromat subjects have superior basic visual functions such as visual acuity (VA), contrast sensitivity (CS), and stereo acuity, compared with participants with normal color vision.

Higher order aberrations of the eye: Part one
TL;DR: In this article, the authors provide a comprehensive literature review of higher order aberrations (HOAs) of the eye, mainly explaining the general principles of such HOAs as well as HOAs of importance.

Simulation of visual acuity by personalizable neuro-physiological model of the human eye
TL;DR: A model of the whole visual train is presented to estimate an individual's visual acuity based on their eye’s physical properties, which takes into account the optics of the eye, neural transmission and noise, as well as the recognition process.

TL;DR: In this paper, the authors compare subjective (Rx) and objective (ObjRx)-based refraction outcomes with two autorefractors models and an aberrometer in eyes implanted with a hydrophobic trifocal IOL (FineVision POD F GF, Physiol, Liege, Belgium).

Long eye relief fundus camera and fixation target with partial correction of ocular longitudinal chromatic aberration.
TL;DR: A combined 32° full field of view refractive fundus camera and fixation target with a -20 to +10 diopter sphere correction range is described and demonstrated, and retinal imaging at various wavelengths is demonstrated.

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.
