Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
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.
