Optical illusions are mainly tricky images that play with our minds and test how well we can see the intrinsic details hidden in a picture. These images help scientists understand how our brain processes visual information and also boost our thinking and reasoning abilities, to make our brain more creative and engaging. Solving these activities often can thus improve our memory and can make us better at solving such issues.
By arranging a series of images, colours, and patterns in a proper form, or playing with the way an object is lit, the brain can be tricked into seeing things at a time that are not even present there. How one perceives the proportion to be seen also depends on the object's shape, colour, or if any other object is hovering around the one which you’re witnessing. These images are thus known for their complexities and are used to improve one’s cognitive strength.
