Why do optical confusion bother us?
The cause of such optical confusion is so difficult how our brain processes visual information. Your brain is a master in the spotting pattern, and when it sees a complete bunch of the same thing – such as 32 and 23, which also have two digits in reverse order – it assumes that everything is the same. This is why your eyes can be right on hidden 33, even without seeing it. Our brains rely on the shortcut to quickly process information, but sometimes, those shortcuts may make mistakes. Optical confusion takes advantage of these small brain cervices, making us another estimate what we are seeing.
