How does an optical illusion work?
OPTICAL illusions are a great way to test your eyesight and cognitive skills, requiring you to really think about and observe what's in front of you.
More often than not, players are required to find something hidden within an image that can't immediately be found on a first glance.
But the more you stare at it, the more your brain tries to help you find the answer.
What you see and what you think you see are two completely different things, but your senses gather information and send it your brain.
Your brain then creates a perception with this information, whereby it fills in gaps when there is incomplete information, or creates an image that isn't even there.
This reaction is actually a survival instinct.
Our brains have evolved to quickly work to piece together any information it can get, before doing its best to figure out the rest.
So when you're looking at an optical illusion, your brain works with what it's got to develop a reality in order to help you see the answer in the image
