Summary

Eye's aberrations have been known to degrade human visual performance and the visual performance is significantly improved when correcting the aberrations in the central visual field. However, how the aberration correction affects the peripheral visual performance is not well understood. Moreover, how central and peripheral vision interacts remains unclear.

To conduct the study, we will use an adaptive optics vision simulator equipped with a Shack-Hartmann wavefront sensor and a spatial light modulator (see details in procedures section of the protocol). This system is capable of noninvasively controlling the eye's optical quality and evaluating visual performance simultaneously over a wide area of visual space. This study provides insights into the visual performance in the periphery visual field, and interaction between central and peripheral visual fields.

The goal of this study is to evaluate the visual performance at central and peripheral visual fields after correcting the ocular aberrations. An optical system equipped with a liquid crystal spatial light modulator will be used to achieve this goal non-invasively.
