Vision Test

Vision Test is a YouTube video uploaded by user bobo39472. This is considered one of the worst screamers out there as the few comments left on it criticized it for being too obvious. It was first uploaded on October 27, 2007.

The video, of course, sets itself up as a vision test to see if the viewer can see letters of the alphabet from various distances. After the process is repeated 5 times, a weird creature appears with a distorted roar in the back.
