Study Details

Study Description

Brief Summary

This purpose of this study is to compare the clinical performance and subjective acceptance of two different daily disposable limbal ring lenses.

Condition or Disease Intervention/Treatment Phase
  • Device: Hema-copolymer Lens
  • Device: etafilcon A Lens
N/A

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.
