Ever wondered what happens to your eyes when you get drunk? This is a clear demonstration using the same tests that are performed by law enforcement officers.
The tests you'll want to pay closest attention to are the Lack of Smooth Pursuit, and the Nystagmus tests. The eyes are clearly less smooth in the drunk video, and demonstrate nystagmus, which is an involuntary twitching motion.
This video includes the following tests:
- Equal Tracking and Device Calibration
- Lack of Smooth Pursuit
- Distinct and Sustained Nystagmus at Maximum Deviation
- Onset of Horizontal Gaze Nystagmus Prior to 45 Degrees
- Vertical Gaze Nystagmus
- Lack of Convergence
- Pupillary Rebound Dilation
