Visual Illusion (also called Visual Illusion) refers to Visual Illusion caused by eye-ball deception through images to achieve artistic or magic-like effects. We often say that we must be based on everything, that is, all what we see is "what we see is you", but what we see with true eyes will not be wrong? Although the eye is a part of the body of an individual, the image visualized by the eye is the most correct, but is perceptually disturbed and stimulated by the surrounding environment (shape, color), which causes the visual sense to generate the illusion of cognitive judgment, namely "visual illusion", for example: measuring with a ruler that a line segment is straight, but the perception by the eye appears to be askew; in short, the "optical illusion" is a phenomenon that the size, shape, color, brightness and relative position of an object are visually judged to be wrong or cause a contradiction. Most of the ways of expression by using the visual illusion are not logical, and the illusion like a fantasy is generated when the viewer watches the work by using different images, colors and perspectives of various angles, but the fantasy phenomenon is often attractive, people often happily accept visual deception and further seek special visual stimulation and surprise.
