Abstract

The recent development of novel optical techniques has made it possible to control the ocularaberrations with high precision and investigate the limits of visual performance. Using thesetechniques, we developed a vision simulator to measure visual acuity in extreme conditions ofhigh-resolution ophthalmic correction, and to study the effects of the optical blur on visualperception. Fast and accurate psychophysical methods were used to obtain reliable results onsmall changes of visual performance. We also used a customised model of visual acuity topredict and understand the relation between the retinal image quality and the visualperception. This work provides novel insight into the optical and neural limitations of visualperformance.
