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

Optical models of the human eye
TL;DR: This review discusses many of the theoretical types of optical models of varying anatomical accuracy, including single, three and four refracting surface variants, and considers which optical model should be used for a particular purpose, adhering to the principle that the best model is the simplest fit for the task.
Journal ArticleDOI
Measurement and correction of transverse chromatic offsets for multi-wavelength retinal microscopy in the living eye.
TL;DR: An image-based method to measure and correct for the eye’s transverse chromatic aberrations rapidly, non-invasively, and with high precision is presented and validated against hyperacute psychophysical performance and the standard chromatic human eye model.
Journal ArticleDOI
Wide-field optical model of the human eye with asymmetrically tilted and decentered lens that reproduces measured ocular aberrations
TL;DR: This work proposes an optically accurate wide-field schematic eye that reproduces the complete aberration profile of the human eye across a wide visual field and outlines a robust reverse building eye modeling technique that is capable of predicting trends beyond those defined explicitly in the optimization routine.

Extending the range of vision using diffractive intraocular lens technology.
TL;DR: The application of new IOL diffractive technology enabled optical characteristics that suggested that an extended range of vision can be obtained without compromising distance vision.

TL;DR: Axons and dendritic arborization could be resolved in primate retinal ganglion cells in vivo, comparing favorably in detail with ex vivo confocal images of the same cells.

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.
