Indeed, what we see with our eyes at a time may not be true but a mere deception. In an optical illusion, what we see at times does not exist and what exists at times is unable to be witnessed by our eyes. Optical illusions are complicated images as many researchers believe that optical illusions are caused when the information taken in by our eyes conflicts with the working of our brain, where the brain interprets the information. However, the brain cannot make sense of what the eyes witness, so it falls back on providing a clean experience thus giving us reasons for conflicts.
An optical illusion at times plays tricks on your vision and teaches us how our eyes and brain work together to see. As we live in a three-dimensional world, our brain gets clues about shading, depth, position, and lighting, to help you interpret what you see. By arranging a series of images, patterns, and colours strategically or playing with the object, the brain can get tricked into witnessing something which is not even there. Now, how you perceive proportion can also be altered depending on the known objects that are projected nearby. Thus, making it clear that this is not magic but an optical illusion.
