摘要：A new phenomenon of visual illusion is described with MATLAB simulating and analyzing the mesh dislocation phenomenon of the myopia, and studying the influence between the degree of myopia, grid shape and grid spacing on the visual illusion phenomenon. Based on the theoretical derivation of the visual images produced by the superposition of light rays in different situations, the theory is greatly consistent with the real phenomena. From the conclusion, it can be seen that there are different phenomenon of visual dislocation when the grid spacing is different from the degree of myopia, and a deep relationship between the cause of the phenomenon and the Poisson bright spot. The results provide a theoretical basis for understanding the mechanism of visual illusion, and help to prevent the possible safety accidents caused by myopia illusion. Meanwhile, they provide reference value for the research of two-dimensional materials with same structure. © 2019, Editorial Board of Optical Technique. All right reserved.
