Summary

This study investigates whether dynamic vision testing can reveal vision impairments that standard concussion checks miss. Researchers will test college athletes who have had a concussion, using computerized vision and balance assessments. The goal is to see if these tests detect lingering issues even after an athlete is cleared to return to play, potentially improving safety in sports.
