Permissible Errors of the Eye Aberrometry

This paper investigates the influence of the human eye’s aberrations on a diffraction image of two points at the retina. These points are located at spatial resolution threshold according to the Raleigh’s criterion. The diameter of a pupil zone was set to 3 mm, at which the eye has the highest sight acuity. We determine that in order to preserve normal spatial resolution of the eye the wavefront RMS of the eye should not exceed 0?1 of the wavelength. Based on this thesis, the criterion is proposed to evaluate permissible errors of eye aberrometry.

Simulation of aberrations of the optical system of the human eye. Part 1. Review and comparative analysis of physical eye models with aberrations

In this paper, we review and make a comparative analysis of physical eye models with aberrations. We propose a doublet lens model, free of prototypes’ drawbacks. By computation of the wave aberration values, we prove the ability of the proposed model to simulate the wave aberrations, identical to those in the human eye.

Aberrations of an Optical System of the Human Eye Chapter 2. Technological errors of a doublet physical eye model with aberrations

The present study considers the influence of technological errors of construction parameters of the optical system of the human eye model on the errors of a simulated wave aberration. We verify the technological possibility of manufacturing the model with an accuracy of wave aberration simulation, sufficient for examining ophthalmic aberrometers
