[0002] Amblyopia usually refers to the vision of one or both eyes being lower than normal, and even after correction, it cannot reach the normal vision standard. This condition may be caused by a variety of reasons, including refractive error, strabismus, form deprivation, etc. Myopia is a common refractive error, which manifests as parallel light rays refracted by the eyeball and focused in front of the retina when the eye is relaxed, causing distant objects to be blurred.

[0003] Amblyopia and myopia patients face many challenges in their daily life and study. They may experience blurred vision, eye fatigue, reading difficulties and other problems, which not only affect their quality of life, but also have a negative impact on their mental health, such as anxiety and low self-esteem. At the same time, the medical and daily service needs of amblyopia and myopia patients also bring a certain economic burden to their families and society.
