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

Optics of the Human Eye
TL;DR: The optical structure and optical properties of the human eye are described, how the retinal image is formed and the factors affecting its quality are described.
Journal ArticleDOI
Statistical variation of aberration structure and image quality in a normal population of healthy eyes.
TL;DR: It is inferred that subjective best focus occurs when the area of the central, aberration-free region of the pupil is maximized, and that correction of the 12 largest principal components, or 14 largest Zernike modes, would be required to achieve diffraction-limited performance on average for a 6-mm pupil.

Anatomically accurate, finite model eye for optical modeling
Hwey-Lan Liou,Noel A. Brennan +1 more
TL;DR: The new model eye provides spherical aberration values within the limits of empirical results and predicts chromatic aberration for wavelengths between 380 and 750 nm and provides a model for calculating optical transfer functions and predicting optical performance of the eye.
Journal ArticleDOI
Accuracy and precision of objective refraction from wavefront aberrations
TL;DR: It is concluded that objective methods of refraction based on wavefront aberration maps can accurately predict the results of subjective refraction and may be more precise and wavefront methods may become the new gold standard for specifying conventional and/or optimal corrections of refractive errors.

Optics of the Human Eye
TL;DR: The first stage in the process of vision is the formation of images of the outside world on the retina at the back of the eye as discussed by the authors, and the optical structure and optical properties of the human eye are described.

Effect of ocular chromatic aberration on monocular visual performance.
TL;DR: The way in which retinal image quality is affected by chromatic aberration is described and the impact of the aberration on visual performance is assessed.

The optical transverse chromatic aberration on the fovea of the human eye.
TL;DR: The results suggest that the optical design of the human eye is optimized to reduce the wavelength dependent phase shift in the optical transfer function, which could be produced by optical TCA.

Lenses for correcting chromatic aberration of the eye.
TL;DR: Experimental results confirmed that this lens performed well over a 14-deg field of view, and a new airspaced system is described which avoids introducing unwanted transverse color.

Calculation of the influence of lateral chromatic aberration on image quality across the visual field.
TL;DR: The results indicate that lateral chromatic aberration is a major factor affecting image quality for obliquely incident rays of polychromatic light, and probably has negligible effect on peripheral acuity but may act to limit aliasing of peripheral patterns.

Image quality of the human eye for eccentric entrance pupils
A. van Meeteren,C.J.W. Dunnewold +1 more
TL;DR: Modulation transfer functions (MTF's) are calculated for central and eccentric positions of small pupils placed in front of the human eye to help to separate optical and retinal contributions to the well-known reduction of visual acuity measured with eccentric pupils.
