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.

Conditions

Dry Eye Syndromes

Outcome Measures

Primary Outcomes (4)

• The frequency of dry eye symptoms

  Participants will complete a pre-intervention survey to measure the frequency of dry eye symptoms.

  Day 1

• The frequency of dry eye symptoms

  Participants will complete a post-intervention survey to measure the frequency of dry eye symptoms.

  Day 30

• The severity of dry eye symptoms

  Participants will complete a pre-intervention survey to measure the severity of dry eye symptoms.

  Day 1

• The severity of dry eye symptoms

  Participants will complete a post-intervention survey to measure the severity of dry eye symptoms.

  Day 30

Study Arms (3)

50% brightness group

EXPERIMENTAL

Participants will be using a computer screen reducing screen brightness 50%.

Other: Brightness

Light App group

EXPERIMENTAL

Participants in this group will use a modulating computer screen tone with flux or night shift app.

Other: Brightness

Control group

NO INTERVENTION

Participants in this group will be a control with no change in screen features
