Optical illusions can be incredibly fascinating. They involve images that have a different objective reality than how they are visually perceived to be. The main varieties of optical illusions include cognitive illusions, physiological illusions and literal optical illusions. Cognitive illusions occur due to unconscious conclusions that we make, while physiological illusions occur due to a particular type of excessive stimulation, which may be the color, position, size, movement, brightness or tilt. Literal optical illusions are those that have different images created than the objects that make up the images. Optical illusions can be very intriguing, in that they may make us question our own perception.
