Study for Remote Investigation of Evaporative Dry Eye Disease

Inclusion Criteria:

* Evaporative loss dry eye disease will be confirmed by screening clinical examination. Patients with evaporative loss dry eye disease will have minimal to no corneal staining and have normal aqueous (water) tear production. Eligible patients with evaporative loss dry eye disease over the age of 18 will be offered study participation.
* There will be no ethnic restrictions on enrollment. All adults (18 years of age or older) with evaporative loss dry eye disease regardless of race or ethnicity will be recruited for participation.
* All adults (18 years of age or older) with evaporative loss dry eye disease , regardless of sex/gender are eligible for recruitment. Women will not be excluded if they are pregnant or breastfeeding.
* All adults age 18 or older with evaporative loss dry eye disease will be recruited for participation. Dry eye disease is not common in the pediatric population and younger children would require assistance with electronic symptom logging and self-performed ocular surface sample collection. Therefore, this study of feasibility of decentralized dry eye disease study will exclude children.
* No treatment is administered in this non-interventional feasibility trial, therefore if pregnant women have dry eye they can participate with no risk to the fetus.

Exclusion Criteria:

* Patients with keratoconjunctivitis sicca (clinically significant decrease in aqueous production) will not be included. This is because the population with this dry eye disease subtype is at higher risk for corneal epithelial breakdown and ocular surface infection.
* Patients unwilling to measure their own tear production at home will be excluded.
* Patients without internet access or reasonable proximity/access to a post box will be excluded.
* Eyedrop use is not an exclusion criterion.
