Q.What is Optical illusion
A.An optical illusion (also called a visual illusion) is characterized by visually perceived images that differ from objective reality. The information gathered by the eye is processed in the brain to give a perception that does not tally with a physical measurement of the stimulus source. There are three main types: literal optical illusions that create images that are different from the objects that make them, physiological illusions that are the effects of excessive stimulation of a specific type (brightness, colour, size, position, tilt, movement), and cognitive illusions, the result of unconscious inferences. Pathological visual illusions arise from a pathological exaggeration in physiological visual perception mechanisms causing the aforementioned types of illusions.
Q.How does it work?
A.(It’s really just your brain taking a shortcut.) 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.Optical illusions harness the shift between what your eyes see and what your brain perceives. They reveal the way your visual system edits images before you’re even made aware of them like a personal assistant,
