This study will evaluate the influence of contact lens optical design on visual performance
using standard and multifocal soft contact lenses (MFCLs).
using standard and multifocal soft contact lenses (MFCLs).
The study will examine visual acuity with various contact lenses, with and without glare
source, in myopes between the ages of 18-39 years old (inclusive) to determine the effect of
different multifocal optical designs on visual performance in the post-fit period.
