Vanishing Head Illusion

Doesn't work for me, but that might be because my left eye is lazy, and doesn't work very well lol.

Its just your blind spot, and because the black "line" is so much contrasted from the rest of the background your brain "connects" the two lines with what is called Shape Continuity.

Blind Spot!

Nifty!

Dude, your head's gone!

Well we all know about the blind spot but i didnt know that in certain circumstances it appears that the brain fills in gaps to cover up what the eye cannot actually see. It seems everyone's brain assumes that the black bar is always continuous even when your eye cannot actually see that part of the bar.....

The human brain is awesome!

Doens't work here.. I focus on the white cross, and it's the left part that seems to turn black, around the cross.. But the guy is stille visible with his head.. And if I move, towards, or backwards, the darkened part turns back to orange.
Maybe it has something to do with the fact that I use a lot the peripherical sight on daily basis? Or should I go to an oculist?

blind spot right?

I actually had to move back to get the effect (I was watching in fullscreen), but when I got it, it was pretty cool. In optical illusion books I used to read as a kid, they often had that illusion somewhere. "Stare at the baby duck and make the mommy duck disappear!" sort of thing. Huh, that one was kind of mean actually. Using the illusion to make your head disappear from your body is pretty clever!

It kinda faded a bit, but since I kept staring at the cross I couldn't be sure. I prefer doing it paper.
