Recently, the 3-year-old baby was found to be myopia 1400 degrees, the top line of the eye chart can not see clearly, the doctor immediately gave the parents a test, found that there is a mutation in the gene, the child has a family genetic disease called FEVR, which may cause blindness when serious.
Partners who wear glasses should more or less know what state myopia should be at 1400 degrees, so how to judge whether the child's vision is good or not during the baby's development?
Your child's visual standards are related to age.
Newborn babies have very poor vision, can only see blurry figures, can not distinguish colors, about 0.01.
A 6-month-old baby can have a vision of 0.1 and will follow larger objects, such as brightly colored toys, with his eyes.
When the baby is 1-2 years old, the baby's vision can reach 0.2-0.3, which is difficult to check the vision at this stage, mostly judged by whether the baby can grasp or find smaller objects.
When the child is 3 years old, he can reach 0.4 and above, at which time the child can be taught to identify the child's vision chart and conduct a preliminary vision examination.
When the child is 4 years old, the vision reaches 0.5-0.6, and the child can undergo an E-word standard eye chart examination.
When children are 5 years old, their vision can reach 0.6-0.8, and some children can reach 1.0.
When children are 6 years old, their vision can reach 0.8-1.0, and children's vision can reach more than 1.2.
At the age of 7, the vision can reach 1.0 and above.
Special note: 4-year-old children with vision greater than or equal to 0.4 is normal; however, if the four-year-old child's vision exceeds 0.6 to reach 0.8-1.0, then it is worse!
This shows that the 4-year-old baby's vision develops in advance, and the reserve of farsightedness is insufficient, and it is likely to develop into highly myopic eyes in the future!
