About

The purpose of this study is to evaluate changes in ocular mucin levels in response to a drying environment in subjects with dry eye disease as well as patients who report no history of dry eye disease.

It is expected that exposure to the dry environment will alter mucin levels in different ways when comparing the two groups.

Full description

This is a single-center, two visit, pilot, drying environment study (CAE). There will be two different groups of subjects enrolled into this study: dry eye subjects and subjects with no prior diagnosis of dry eye.

All subjects will undergo safety and dry eye assessments as well as tear collection prior to and after being exposed to a dry environment. They will also return the following day to undergo dry eye assessments, tear collection, and safety procedures again.
