Many parents are not clear about their children’s amblyopia or myopia concept, just know that the child is unable to see the surrounding objects. A different principle: amblyopia: infants are born with less than 1% of adult vision, and as they grow older, the visual cells of both eyes continue to develop and improve. 5 years old is an important period in the development of visual function, visual development continues until 6 to 8 years old, such as this period for some reason caused by binocular vision impairment, the visual cells do not get normal stimulation, visual function is stuck in a low level, binocular vision is low If you can only use one eye to see things, over time repeated stimulation of the eye visual development, but can not look at the other eye development is delayed, the formation of monocular amblyopia. Amblyopia can occur during visual development, mostly starting at the age of 1 to 2. The earlier the onset of amblyopia, the more severe it becomes. Myopia: When parallel light rays are focused in front of the retina through the refractive system of the eye in a relaxed state, it is called myopia. 4-6 year old children’s vision has gradually matured and the clarity of vision has increased, reaching 1.0 at the age of 6, basically reaching the level of adults. However, because parents are often busy with their own affairs and neglect the care of their children, as well as some objective reasons, many children have refractive errors. Two: different standards: Amblyopia: According to the new standards for amblyopia at the 2010 annual meeting of the eye: children under 3 years old, with glasses corrected vision for less than 0.5; 4 to 5 years old, with glasses corrected vision for less than 0.6; 6 to 7 years old, with glasses corrected vision for less than 0.7; or more than 2 lines of difference in vision after correction of both eyes. Myopia: 1.0 is a cutoff, if the child’s visual acuity is below 1.0 it needs to be corrected for refractive error. Three: treatment is different: amblyopia: generally through amblyopia training treatment, the earlier the treatment effect is better, if you can start treatment before the age of 5 years old the best effect; after 10 years old the effect is relatively poor. Myopia: improve and control visual acuity through prescription glasses or wearing keratoplasty lenses.
