Summary

The purpose of this study is to assess eyelid margin staining, termed "lid wiper epitheliopathy" (LWE), in three populations. The hypothesis is LWE will be more prevalent in symptomatic contact lens wearers than non-symptomatic contact lens wearers and least prevalent in asymptomatic non-contact lens wearers.

Conditions

  • Dry Eye
