Amblyopia is a visual development, as a result of visual deprivation and / or abnormal binocular interaction caused by the lack of visual cells in the effective stimulation, resulting in unilateral or bilateral visual acuity less than normal children, the general eye examination no abnormal foveal . Some cases, proper treatment can be cured. Young people in the crowd in the prevalence of amblyopia was 2% -4%. Human vision has a gradually improve and consolidate the process that the process for the development of visual function, but also accompanied by some degree of structured. After birth and other glasses systems and organs of the body, like the visual function of the system is not perfect, does not sound to sound by a function between the developmental stages. In the development process need to have normal eye structure, based on need appropriate visual stimulation, vision systems need to be exercised properly in order to be fully functional training. To determine whether the development of normal vision, a child should first know the different age range of normal vision. Depending on the application of different methods (OKN, VEP, PL) of infant visual acuity measured by the published literature reports that most experts believe that one month after birth, newborn and child vision was light perception ~ front manual, 2 months, visual acuity was hand movement ~ 0.01,3 0.02,4 months from 0.01 months, visual acuity visual acuity was 0.02 ~ 0.05,6 months, visual acuity was 0.06 ~ 0.08,8 0.1,1 months old age of 0.2 ~ 0.5 ~ 0.6,3 0.3,2 may reach the age of around 1.0. However, studies have also pointed out that there is a difference of visual development, some earlier, some eyeglasses later, but most scholars believe that after 6 years of age (or even 10 years old) before they can develop into normal adult vision. Visual function in children before the age of 6 have not yet fully mature, depending on the function is not sound, not consolidation, it is a malleable variable stage, all factors that impede visual stimulation can block the development of visual function, to stop development of visual function , growth retardation, developmental deficiencies or dysfunction, to form the visually impaired. Amblyopia is a treatable disease, visual defects. When young children detected by sight, if found early, treatment can be cured in time. Amblyopia is usually divided into strabismic amblyopia, refractive amblyopia, and form deprivation amblyopia. Visual inspection is to discover an important means of amblyopia and strabismus, usually through light reflex, red reflex, pupil testing, fundus examination, alternate cover test and the priority watch to understand the law a few months after birth to 3-year-old child's visual function situation, and after 3 years of age is feasible eyeglass frames vision tests. Early detection of amblyopia and strabismus amblyopia treatment is the key, if the treatment began before the age of 5 the best, but because of amblyopia is often found too late to affect efficacy. Treatment: 1 for ametropia amblyopia associated with the first correction should be wearing glasses. Two eyes for binocular vision or corrected visual acuity differences in the amblyopia treatment or suppression should be performed to cover the treatment. 3, watch as the center for the amblyopic eyes of patients, eye cover or suppress health while training for amblyopia possible, or as fine eyesight stimulation. 4 for the next fixation in amblyopic eyes were feasible for the red filter treatment. Amblyopia is a visual development, as a result of visual deprivation and / or abnormal binocular interaction caused by the lack of visual cells in the effective stimulation, resulting in unilateral or bilateral visual acuity less than normal children, the general eye examination no abnormal foveal . Some cases, proper treatment can be cured. Young people in the prevalence of amblyopia in 2% -4%.
