Video games could be the new treatment for lazy eye
NCT ID NCT05522972
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study is testing whether playing video games and doing special vision exercises can improve eyesight in both children and adults with amblyopia (lazy eye). Researchers will measure changes in visual acuity, depth perception, and contrast sensitivity before and after the training. The goal is to see if the brain can learn to see better through these activities.
