In the clinic or at the point of injury: advanced cognitive assessment.

Introducing the future of mobile assessment technology: EYE-SYNC® by SyncThink overcomes the limitations of traditional cognitive testing to provide an easy-to-use, rapid, objective tool for initial screening and recovery monitoring. Caution - EYE-SYNC is an investigational device, limited by United States law to investigational use.
