An optical illusion (also called a visual illusion) is characterized by visually perceived images that differ from objective reality. The information gathered by the eye is processed in the brain to give a percept that does not tally with a physical measurement of the stimulus source. There are three main types: literal optical illusions that create images that are different from the objects that make them, physiological ones that are the effects on the eyes and brain of excessive stimulation of a specific type (brightness, tilt, color, movement), and cognitive illusions where the eye and brain make unconscious inferences. (according to wikipedia)
I searched for optical illusions on the web and got some interesting results:

The green circle doesn't exist, and if you stare at the black + all of the dots will fade away. But, really, all of the dots are pink. (click on the picture to see it work) Cool, no?
Enough of that for now...my eyes need a break!
this is sooo cool!! I don't understand how it works though....ahh computers confuse me...
ReplyDeletehaha i know, me too!
ReplyDeleteAh, I just realized that I posted the same optical illusion! For some reason, the animation automatically works on mine. I think it is because I literally clicked the image and dragged it to my page!
ReplyDeleteBut seriously, it is so weird! It makes me wonder if I am really seeing everything correctly!
My eyes hurt and I don't trust reality anymore >.<
