Computer Screen Properties Study

Not Applicable

Completed

• Conditions: Dry Eye Syndromes
• Interventions: Other: Brightness

• Registration Number: NCT05042960
• Lead Sponsor: NYU Langone Health

Brief Summary

The purpose of this study is to identify how various popular methods of changing computer screen settings affect dry eye symptoms (eye pain, grittiness, tearing, burning, etc.). Specifically, this study will examine if there are differences in effects of blue light blocking (F.lux app or night shift) versus reducing screen brightness on the symptoms of dry eye.

Detailed Description

After the initial survey, participants will be randomized by a randomization tool internal to Redcap to be in one of three arms of intervention: no intervention, screen brightness reduction to 50%, and tone modulator application. Instructions will be e-mailed to participants to explain the steps they must take depending on which treatment arm they are randomized to. Adherence will be monitored and assessed at the time of post-intervention survey. If participants have issues with the software of complying, they will be able to contact the research team at any point.
