What is an Optical Illusion?

The human brain puts images together because it has learnt to expect to see things, but sometimes the data might get a little confused.

We may see an illusion because we know what we are expected to see, even though part of a picture or design may not be completely there. The basis of this is in how we perceive things.

That almost explains everything right there. If our brain and eye’s did not function as they do, we would not see illusions like we do.
