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

Numerical study on statistical properties of speckle pattern in laser projection display based on human eye model
TL;DR: In this paper, the laser speckle pattern on human retina for a laser projection display is simulated, and the statistical properties of the laser sparseness are numerical investigated by introducing a specific eye model "Indiana Eye".

Optical computing for application to reducing the thickness of high-power-composite lenses.
TL;DR: The eye model and Taguchi experiment method is applied, combined with design optimization for hyperbolic-aspherical lens, to significantly reduce the lens thickness by more than 30%, outperforming the average thickness reduction in general aspherical lens.

Development of a human eye model for visual performance assessment
TL;DR: In this paper, a biometry-based human eye model was developed by using the empirical anatomic and optical data of ocular parameters, which is highly potential for investigating visual performance in ordinary lighting and display conditions and under the influence of glare sources.
Raytracing a Schematic Eye
TL;DR: A schematic eye can be made to closer approximate the living eye in any individual if the technique can be extended to very accurately model all optical aspects of an individual’s eye requiring only measured data of the individual using non-invasive metrics such as interferometry.

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.
