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

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.

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.

Relation between the chromatic difference of refraction and the chromatic difference of magnification for the reduced eye
TL;DR: A simple model for calculating the chromatic difference of magnification for the human eye is provided and the significant increase in this aberration produced by experimental use of artificial pupils is shown.
