More and more parents are taking their children’s early vision development seriously, and after summer vacation our Children’s Hospital’s eye clinic is often filled with young parents holding their little ones in their arms. “Doctor, I’d like to have a comprehensive eye examination for my child.” “The baby was born prematurely, I want to see how his vision is developing?” Looking at these cute babies and those desperate parents, I felt some relief. After all, with the popularization of health care knowledge and awareness of the younger generation of parents, and with the development of medical technology, more and more congenital eye diseases can be diagnosed and detected at an early stage, and more and more visual disabilities can be rehabilitated through early intervention and treatment. We pediatric ophthalmologists have a great responsibility for early screening and intervention, which must begin at age 0. For parents, how can they prevent their children from developing early visual problems? First of all, for some high-risk children, an eye examination must be performed 3 months after birth (see the article “Which babies need early eye screening”); up to the age of 3 years old children must undergo a comprehensive eye examination to rule out possible refractive errors, strabismus and amblyopia; 7 years old preschoolers need to be highly followed up on the visual development and refractive status changes; up to the age of 8-13 years old, the focus is on the prevention of myopia formation; secondly, up to the age of 3 years old, the focus is on the prevention of myopia formation; and secondly, the focus is on the prevention of nearsightedness. Second, children under the age of 3 must develop healthy living and eating habits, not too much exposure to TV, computers and cell phones, not exposed to bright light, not long-term partiality and picky eating; Third, if there are squinting, rubbing the eyes, squinting, blinking, and close vision abnormalities, it is important to bring your child in as soon as possible for a checkup. The pediatric ophthalmologist must have a set of comprehensive assessment of the child’s visual examination methods, such as visual behavior, refractive status, fundus and retinal optic nerve examination, subjective and objective visual examination, a series of examinations and a period of follow-up, to give each child a visual health assessment, to give each parent a reasonable health care guidance, to give each small patient an appropriate intervention and timely treatment, is the responsibility of the pediatric ophthalmologist. It is the duty of pediatric ophthalmologists to give every child a visual health assessment, give every parent a reasonable health care guidance, and give every little patient an appropriate intervention and timely treatment. Currently, the commonly used clinical visual screening equipment for children is becoming more and more accurate and easier to operate and cooperate with, so we can not tell any child to wait for cooperation before coming back to the examination because of lack of cooperation, because, the critical period of visual development is within 2-3 years old. Many diseases can be treated at this time and the child’s vision will be maximized.
