Second, affect learning, career choice and life Amblyopia leads to the inability of both eyes to form stereo vision, because the brain can only get the visual signal from the unilateral healthy eye input, the brain can not form a stereo image, will lead to the patient has no stereo imagination ability. The prevention and treatment of amblyopia should be done with “three hearts”: carefulness, persistence and patience. First of all, carefulness. Parents should pay attention to the child’s eyes, and find that the child is always squinting, frowning and tilting his head when looking at things. Watching TV closer and closer, two eyes can not look in the same direction, you need to immediately take the child to the regular hospital to ask the ophthalmologist examination. The second is persistence. Before the child’s visual development is fully mature, the amblyopia condition can be repeated. Therefore, parents should be persistent in bringing their children to the hospital for regular follow-up. During the treatment period, follow-up visits to the hospital are usually once a month for the first 6 months, and every 3 months to 6 months thereafter, for at least 3 years.
