When it comes to youth vision loss, people first think of myopia, but ignore the more serious problem of amblyopia in children. But according to statistics, 12 million of the country’s 300 million children suffer from amblyopia. Amblyopia is a common and prevalent disease among children worldwide, with a prevalence rate of 4%. Amblyopia and myopia are two different eye diseases. It is because many parents lack knowledge of amblyopia and cannot correctly distinguish between amblyopia and myopia that 89% of amblyopic children do not receive timely and effective treatment, missing the best time for treatment before the age of 12, thus causing lifelong visual disability. Children with amblyopia often show the following symptoms: they are used to squinting and squinting when looking at things, they have no sense of dimensionality, they walk with an unsteady gait, they fall down inexplicably, they are active and inattentive, they cannot follow people or objects flexibly, they read and write with their eyes close to the book, they are prone to writing out of order, they have poor eye-hand coordination, they look at people or objects with one eye while the other eye is skewed, they are very smart but they always have poor academic performance because they cannot see the blackboard, etc. Parents should consider whether their child has amblyopia if they find the above phenomenon. The danger of amblyopia is more serious than myopia, myopia can be effectively corrected by wearing myopic glasses, which basically does not affect learning and work. Amblyopia, however, cannot be corrected to a normal level even with glasses, and most of the vision is still dark, hence the medical definition of amblyopia as a “visual disability. Amblyopia has a significant impact on children’s physical and mental health, learning and employment. Because of their poor vision, children with amblyopia have difficulty concentrating, which affects their academic performance in the long run. More seriously, amblyopia can make some children become inferior, withdrawn and autistic, which can affect their life. With the rapid development of technology, many occupations and types of work are not suitable for amblyopic patients, such as the PLA special forces, various drivers, athletes, modern machinery operation, precision instrument operation, surgical microsurgery, etc., which will bring lifelong regret to the future of amblyopic children and families. In the United States, Japan and other countries, young children from 18 months to start regular vision checks, however, in our country many parents have not paid enough attention to their children’s vision problems, coupled with the fact that many parents can not yet correctly distinguish between myopia and amblyopia, thus delaying the best time for examination and treatment, we recommend that parents should regularly check their children’s vision, if the diagnosis of amblyopia, parents should take their children to receive treatment as soon as possible, because The younger the age, the better the treatment effect, while the older the age, the more difficult the treatment and the slower or less effective the treatment.
