Flicker glasses sharpen young Athletes' minds, study suggests
NCT ID NCT07162545
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tested whether wearing stroboscopic glasses during practice could improve cognitive skills in 34 adolescent male volleyball players. For eight weeks, the players wore the glasses for 10 minutes a day, two days a week, while training. Researchers measured changes in visual-spatial perception, attention, and cognitive function to see if the training had any effect.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- stroboscopic visual training (wearing stroboscopic glasses during practice)
- What this could lead to
- If it works, this could point toward a simple way to boost cognitive skills like focus and spatial awareness in young athletes.
- What could go wrong
- This is a small, early study with only 34 participants, all adolescent male volleyball players, so results may not apply to others. The training effect may be small or not last long.
