Abstract: human vision has a process of gradual formation, perfection and consolidation. This process is the development of visual function, accompanied by some degree of structural perfection. After birth, like other systems and organs of the whole body, the function of the visual system is not perfect, and there is a stage of functional development from imperfect to perfect., Is your child’s vision developing normally?, “Amblyopia is the lack of effective stimulation of visual cells caused by visual deprivation and / or abnormal interaction of both eyes during visual development, resulting in unilateral or bilateral corrected visual acuity lower than normal children of the same age. There is no abnormal macular fovea in general ophthalmic examination. Some cases can be cured after appropriate treatment. The prevalence of amblyopia in adolescent population is 2% – 4%. ”In the investigation of children’s eyesight, the director of the 85th Hospital of the Chinese people’s Liberation Army said., Human vision has a process of gradual formation, perfection and consolidation. This process is the development of visual function, accompanied by a certain degree of structural perfection. After birth, like other systems and organs of the whole body, the function of the visual system is not perfect, and there is a stage of functional development from imperfect to perfect. In this development process, we need to have normal eye structure as the basis, also need appropriate visual stimulation, and need the visual system to properly exercise its function in order to obtain sufficient training., In order to determine whether a child’s vision is normal, we should first know the normal vision range at different ages. According to the literature reports published on the application of different methods (OKN, VEP, PL) to measure the visual acuity of infant children, most experts believe that the visual acuity of newborns and children one month after birth is light vision ~ visual acuity, The visual acuity was 0.01 ~ 0.01 at 2 months, 0.01 ~ 0.02 at 3 months, 0.02 ~ 0.05 at 4 months, 0.06 ~ 0.08 at 6 months, 0.1 at 8 months, 0.2 ~ 0.3 at 1 year old and 0.5 ~ 0.6 at 2 years old. It may reach about 1.0 at 3 years old. But at the same time, some studies have pointed out that there are differences in visual development. Some people are early and others are late, but most mathematicians believe that they can develop into normal adult vision after the age of 6 (or even 10)., Children’s visual function is not mature before the age of 6, and the visual function is not perfect and consolidated. This is a plastic and changeable stage. All factors that hinder visual stimulation can block the development of visual function, stop the development of visual function, delay the development, underdevelopment or functional disorder, so as to form amblyopia., Amblyopia is a treatable visual defect disease. Children can be found through visual acuity test. If found early, they can be cured in time. Amblyopia is usually divided into strabismus amblyopia, refractive amblyopia and form deprivation amblyopia. Visual examination is an important way to find amblyopia and strabismus. Generally, the visual function of children from a few months to 3 years old can be understood through light reflection, red light reflection, pupil detection, fundus examination, alternating covering test and priority viewing method, while visual examination is feasible after 3 years old. Early detection of amblyopia and strabismus is the key to amblyopia treatment. If the treatment can be started before the age of 5, the effect is the best, but amblyopia is often found too late, which affects the curative effect.,
does your child’s vision develop normally?
“Amblyopia is the lack of effective stimulation of visual cells caused by visual deprivation and / or abnormal interaction of both eyes during visual development, resulting in unilateral or bilateral corrected visual acuity lower than normal children of the same age. There is no abnormal macular fovea in general ophthalmic examination. Some cases can be cured after appropriate treatment. The prevalence of amblyopia in adolescent population is 2% – 4%. ”In the investigation of children’s eyesight, the director of the 85th Hospital of the Chinese people’s Liberation Army said.
human vision has a process of gradual formation, improvement and consolidation. This process is the development of visual function, accompanied by some degree of structural perfection. After birth, like other systems and organs of the whole body, the function of the visual system is not perfect, and there is a stage of functional development from imperfect to perfect. In this development process, we need to have normal eye structure as the basis, also need appropriate visual stimulation, and need the visual system to properly exercise its function in order to obtain sufficient training.

children’s visual function is not mature before the age of 6, and the visual function is not perfect and consolidated. This is a plastic and changeable stage. All factors that hinder visual stimulation can block the development of visual function, stop the development of visual function, delay the development, lack of development or dysfunction, so as to form amblyopia.
