A visual effect caused by
drug use or lack of sleep. The world looks as if your eyes are opening and closing extremely fast, but you can't feel any eye movement, and others can't tell you're seeing funny. It is like the opening and closing of a
camera shutter on high speed capture. And it can be very disorienting.
"Dude, I roofied
myslef and now I got mega
shutter vision, the world looks like discovery channel or something."
"Damn, I've been
up for days and the world looks like it's a cartoon; crazy-ass shutter vision yo."
