A 6-month-old baby is usually not nearsighted, unless it is congenitally nearsighted.
The eye axis of babies is shorter than that of adults, so they are farsighted for a period of time after birth, and as they get older, their eye axes will gradually become longer, and the degree of farsightedness will also decrease slowly. If the baby has congenital myopia, it is usually caused by the unsound development of the eyes during the fetal period, and this kind of myopia is usually high myopia.
At present, myopia is gradually presenting a trend of low age, so children should pay attention to eye habits from childhood, reduce the use of electronic products, parents can wait until the child is three years old to the hospital to check the visual acuity, to understand the state of the child’s eyes, and then according to the child’s checkups, go to the hospital on a regular basis for review.
