NCT ID NCT07340359
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tested whether a special yellow-light, anti-glare phone screen could reduce eye strain and dryness caused by using a phone for 2 hours in a dim room. 70 adults with mild nearsightedness took part. Researchers measured tear quality, eye redness, and other signs of eye fatigue before and after reading. The goal was to see if this screen offers better protection than a standard screen.
