Brief summary

This study will evaluate the influence of contact lens optical design on visual performance using standard and multifocal soft contact lenses (MFCLs).

Detailed description

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.
