Abstract: the key period of eye development is before the age of 3, and the sensitive period is before the age of 9. At this stage, it is very important to protect the eyes and treat problems in time. Many eye diseases are difficult for parents to find, such as amblyopia.
there are many people with myopia, especially children’s myopia. There are many factors of children’s myopia, which are generally dominated by genetic and environmental factors, so it is troublesome in treatment. Many parents do not know the standards of children’s visual development, so when children have myopia, I don’t know when it started, which led to serious vision problems.
what is the standard of children’s visual development? The following is a detailed introduction, so that we can have a good understanding of such problems. Parents can also pay attention to children’s problems all the time, which is also a kind of protection for children’s eyesight.
1. Children’s vision development standard
in order to determine whether a child’s vision develops normally, 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 earlier and others are later, but most mathematicians believe that normal adult vision can develop after the age of 6 (or even 10).
2. Time for children to start visual acuity examination
1) the key period of eye development is before the age of 3, and the sensitive period is before the age of 9. At this stage, it is very important to protect the eyes and treat problems in time. Many eye diseases are difficult for parents to find, such as amblyopia. Ophthalmologists suggest that eye examination should start at birth (especially premature infants and children who have inhaled oxygen at birth) and should be checked as often as height and weight.
2) now, there are vision examination methods and instruments suitable for children before the age of 3. At the age of about 1 year old, whether there are vision problems or not, the health doctor will suggest that parents (especially when both parents are highly myopic) take their children for a vision examination. If there are problems, the treatment before the age of 3 is very successful. After the age of 3, parents are advised to take their children for mydriatic optometry to thoroughly understand their children’s eye health.
have a good understanding of children’s vision development standards through the above introduction. They also have a detailed introduction to when the examination is the best. Therefore, parents should not only concern their children’s health, but also pay attention to their children’s vision problems, so as to make their children have a good vision.
