Glasses that fight nearsightedness: a new hope for kids?
NCT ID NCT05689567
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests whether special 'peripheral focus-out' glasses can prevent nearsightedness (myopia) in Chinese children aged 6 to 8. Over two years, 160 children will wear the glasses at least 8 hours a day. Researchers will measure changes in their vision to see if the glasses help keep eyes healthy.
