This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed This study
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.

Summary

This study tested whether a new dynamic color temperature mode on screens can prevent dry eye and visual fatigue. Thirty adults read text on a screen for 50 minutes under different color settings. Researchers measured eye fatigue and dryness before and after to see if the new mode helps.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
dynamic color temperature change mode
What this could lead to
If it works, this could lead to screen settings that reduce eye strain and dryness for people who use computers or phones for long periods.
What could go wrong
This was a very small, completed study with only 30 participants, so results may not apply to everyone. The effect may be minor or not noticeable in real-world use.
