Compared with conventional amblyopia training, polarized 3D visual function network training can activate various cortical areas of the brain through richer and more colorful stimulation, and achieve the role of strengthening poor eye function without masking; 2. The polarization 3D training uses polarization glasses to play the role of binocular vision separation with accurate color display and more realistic stereoscopic sensation, and can be adjusted by individualizing each parameter (such as the contrast, color, movement speed, size, energy, etc. of each eye) to artificially break the pathological structure and re-adjust the balance of binocular vision function, so that plasticity can be successfully realized and the training program can be truly individualized; III. For children with nystagmus, polarization training can be used to improve visual acuity and enhance gaze stability; for children with ptosis, no masking is required and the function of the poor eye can be strengthened; vii. For children who are bored and cannot cooperate well, the polarization training program has a game-like level display, which is more interesting and greatly improves the efficacy of amblyopia training; viii.
