The Vanishing Head Illusion

I was researching on the perception for my software project and came across this oldie. It brought smile to my face as I was remembering how fascinating it was to me as a kid.

Try this for experiment. Close your right eye and look at the X with your left eye. Now get closer to the monitor until the A or O disappears. That's your blind spot. Get closer and it reappears!

That's where your optic nerve is located.

Watch this video for the vanishing head illusion.


Fascinating, isn't it?

Do this experiment too. Close your right eye and go in for a closer look at the red dot with your left eye.

The blue line appears unbroken!

This reminds me of what Ramtha asked (J. Z. Knight): do the eyes see or the brain?

This brings the age old question: are what we seeing real or illusion?

Who am I who is seeing all those images? Why are we seeing colors? And so on and on.

Plenty of thinking to do.
