Participants with mild to moderate dry eye disease will wear the BriTer Eyez Moisture Vue™ On Demand Disposable Moisture Chamber attached to their eyeglass spectacles for two hours. Objective tear film measurements and symptom surveys will be collected before and after device wear.

A disposable silicone moisture chamber device designed to attach to eyeglass spectacles to increase periocular humidity and reduce tear evaporation. Participants will apply the device bilaterally to their spectacles and wear it for two hours under supervised conditions. Ocular surface parameters and dry eye symptoms will be assessed before and after device wear.

The mean change in non-invasive tear break up time will be measured using the Bruder Ocular Surface Analyzer at baseline and after 2 hours of device wear. NITBUT reflects tear film stability and will be reported as the mean difference between post wear and baseline values in seconds.

The mean change in tear meniscus height will be measured using the Bruder Ocular Surface Analyzer at baseline and after 2 hours of device wear. Tear meniscus height is an indicator of tear volume and will be reported as the mean difference between post wear and baseline values in millimeters.

The mean change in tear osmolarity will be measured using the TearLab Osmolarity System at baseline and after 2 hours of device wear. Tear osmolarity reflects tear film homeostasis and will be reported as the mean difference between post wear and baseline values in milliosmoles per liter.

The mean change in the Standardized Patient Evaluation of Eye Dryness total score will be assessed using the SPEED questionnaire administered at baseline and after 2 hours of device wear. Results will be reported as the mean difference between post wear and baseline total scores.
