Children's vision development standards and when to start vision examinations

Nowadays, there are many people with myopia, especially children. The number of myopia cases among children is increasing. There are many factors causing myopia in children, which are generally mainly genetic and environmental factors. Therefore, the treatment is also quite troublesome. Many parents do not understand the standards of children's vision development very well, so when their children develop myopia, they do not know when it started, which causes their vision problems to become very serious.

So what are the standards for children's vision development? The following is a detailed introduction so that everyone can have a good understanding of this issue. Parents can also always pay attention to such issues for their children, which is also a kind of protection for their children's eyesight.

Children's vision development standards:

To determine whether a child's vision is developing normally, we should first know the normal vision range at different age stages. Based on the literature reports on measuring the visual acuity of infants using different methods (OKN, VEP, PL), most experts believe that the visual acuity of newborns and infants one month after birth is light perception ~ eye and manual, two months old is eye and manual ~ 0.01, three months old is 0.01 ~ 0.02, four months old is 0.02 ~ 0.05, six months old is 0.06 ~ 0.08, eight months is 0.1, one year old is 0.2 ~ 0.3, two years old is 0.5 ~ 0.6, and may reach about 1.0 at three years old. But at the same time, some studies have pointed out that visual development varies, some earlier, some later, but most scholars believe that normal adult vision can only be developed after the age of 6 (or even 10).

When to start vision examination for children:

1) The critical period for eye development is before the age of 3, and the sensitive period is before the age of 9. During this stage, it is important to protect the eyes and treat any problems in a timely manner. Many eye diseases are difficult for parents to detect, such as amblyopia. Ophthalmologists recommend that eye examinations should begin at birth (especially for premature babies and those who were born with oxygen) and should be checked as frequently as height and weight.

2) Now, there are methods and instruments suitable for vision examination of children under 3 years old. Around the age of 1, regardless of whether there are vision problems or not, health care doctors will recommend that parents (especially if both parents are highly myopic) take their children for a vision test. If there are problems, treatment before the age of 3 is very likely to be successful. After the age of 3, it is recommended that parents take their children to do a mydriasis eye test to thoroughly understand their children's eye health.

Through the above introduction, we have a good understanding of the children's vision development standards. As for when is the best time to check, the above also has a detailed introduction. Therefore, parents should not only pay attention to their children's physical health, but also pay attention to their children's vision problems in normal times. Only in this way can children have good vision.
