The World of Optical Illusions
Speaker Colin Hopper
New members welcome

Optical Illusions occur when the brain misinterprets what is actually visible to the eye.   Knowledge and memory give us an expectation, and then logic is applied but sometimes the brain assumes the wrong thing.

Prejudice can also affect our impression of what is there, and tiredness can play tricks too. The brain relies on our long-term memory to provide clues and inform it of familiar and recognisable things, and it will often fill in gaps and replace missing lines to help the eyes identify what is there.

The information gathered by the eye is processed in the brain to give a perception that does not tally with what is actually there.
