What needs to be specially explained is that when the human eyes watch the scenery at different distances, the ciliary muscle will automatically adjust the curvature of the lens, so that the eyeballs will produce three linkage theories of miosis, convergence, and adjustment, so as to adjust the viewing angle and focal length to make the scene seen by the eyes clear; and the 3D stereoscopic image produces a sense of distance such as far, near, deep, and shallow, so that when the eyes watch the 3D stereoscopic image through the above-mentioned 3D glasses, they will continue to move through the eye muscles. In order to obtain a clear image; then, the continuous physiological adjustment mechanism will invisibly burden the eyes, which will cause discomfort such as vomiting, dizziness and visual fatigue after watching 3D stereoscopic images for a long time. , greatly reducing the entertainment that 3D stereoscopic images originally expected to bring.
