Contact Lens Optics and Visual Performance

Completed · Not applicable

Conditions studied: Myopia

In brief

This study will evaluate changes in visual performance at different pupil sizes between a single vision soft contact lens and multifocal soft contact lens, and compare refractive error measured between these two lenses with an autorefractor and an aberrometer
