Getting concussed as an athlete is not a great experience. What you do afterwards is very important though. EYE-SYNC is a compact head-mounted eye tracking device that analyzes eye movement impairment using virtual reality. It lets you perform a 60 second evaluation to protect the health of your athletes.
The device weighs less than 5 pounds. The technology has already been tested on over 10k soldiers and athletes. More information is available here.
