Detailed Description
This is a subject-masked, dispensing study designed to evaluate the clinical performance and subjective acceptance when comparing two different daily disposable limbal ring lenses. Limbal ring lenses, which as well as correcting vision, have a colored ring which enhance the wearer's iris and are particularly popular in East Asian countries.
