A sort of visual assessment or examination known as an optical illusion test uses optical illusions to measure a person's vision, specifically their ability to perceive depth, color, contrast, and other visual phenomena. These tests are intended to evaluate how the brain and eyes interact to interpret and process visual data.
A series of images or patterns that contain optical illusions are frequently used in optical illusion vision exams. These deceptive sensations of size, form, movement, or color can be produced by these illusions, and they can disclose specific traits of a person's vision and visual processing skills.
