Which Circle Is Larger? Optical Illusion ANSWER DOWN BELOW!!
When you look at something, what you’re really seeing is the light that bounced off of it and entered your eye, which converts the light into electrical impulses that your brain can turn into an image you can use. The process that takes about a tenth of a second but your eyes receive a constant stream of light, an incredible amount of information, so it’s really difficult for your brain to try to focus on everything at once. It would be like trying to take a sip of water from a firehose. So your brain takes shortcuts, simplifying what you see to help you concentrate on what’s important, which helps compensate for your brain’s tenth-of-a-second processing lag. This trait helped early humans survive encounters with fast predators – or at the very least avoid running into obstacles like trees.
Optical illusions fool our brains by taking advantage of these kinds of shortcuts.
