Retinal photoreceptors are essentially directed towards the centre of the eye’s pupil. It was suggested that the photoreceptors directionality is linked to the optical aberrations induced by the cornea and crystalline lens in the eye in a way that the total system performance isoptimised. We show that cone irectionality can be modelled using a two-dimensional Gaussian function whose parameters vary according to the measured monochromatic aberrations of the eye. Our modelling is based on a hypothesis that cones directionality is optimised so that the resulting retinal image quality is maximised. This methodology can also be used in automatic image enhancement systems for correcting higher-order aberrations.

Citation counts are sourced monthly from Scopus and Web of Science® citation databases.

These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.
