The growth of children is always a very important part of parents' hearts. Parents are afraid of what kind of accidents their children may encounter during their growth process. Especially in this society where anything can happen. Vision problems have become a very important issue in the real life of many children, and many children have vision problems. What is the normal visual acuity of a child?
What is the normal visual acuity of a child
Children's vision is generally within the normal range, and as their physical and intellectual development continues, their vision gradually improves. A 4-year-old child has a visual acuity of 0.4-0.6; A 5-year-old child has a visual acuity of 0.6-0.8; And before reaching school age, one can basically achieve a normal visual acuity of 1.0. It should be clarified that some children have slightly lower visual acuity than their peers, but their refractive error is within the normal range. Their visual acuity will reach normal with age, which belongs to slightly delayed visual function development; Some children have problems with refractive error, and it will be difficult for their vision to reach normal levels in the future. Therefore, when you find that your child's vision is below the normal range, you should seek medical advice promptly.
Under what circumstances do children need to wear glasses
Children with amblyopia, who cannot achieve normal corrected vision, should wear glasses as early as possible, which is beneficial for treating amblyopia and promoting the development of visual function. The development of visual function mainly occurs in childhood, especially at the age of 5-6. After the age of 12, it is difficult for visual function to return to normal. Some children with strabismus should also wear glasses early and try to correct strabismus through the optical principles of glasses. Some children can correct strabismus through glasses, and for those who have not seen any effect after wearing them for a period of time, surgical correction should be considered. Children whose corrected vision can reach the normal range need to decide whether to wear it or not based on their eye condition. If it affects learning, shows visual fatigue, or tilts their heads to see things, they need to wear it. Wearing glasses is actually a preventive measure, and parents should follow the doctor's advice without worrying too much, which is beneficial for the treatment of myopia in children.
A child's normal vision will change with age, but if the child's vision is within the normal range, parents don't have to worry. But if there are any unexpected situations, it is necessary to take the child to the hospital for examination, which is more reliable. With the help of the doctor's treatment, I hope every child can grow up healthy.
