What is normal vision for children?

Children's eyes are very fragile and need special protection. Parents should try to ensure that their children use their eyes correctly and reasonably, so as to avoid myopia caused by glasses. Children's retinas are not fully developed yet. If they become nearsighted at a young age, it will be very difficult to recover later. The child may need to wear glasses all year round, which will have a great impact on his future life. So, what is normal vision for children?

Children's vision is more or less within the normal range. Generally speaking, as children's physical and intellectual development continues, their vision gradually improves. The visual acuity of a 4-year-old child is 0.4-0.6; the visual acuity of a 5-year-old child is 0.6-0.8; and before school age, it can basically reach normal visual acuity of 1.0. It should be made clear that some children's vision is slightly lower than that of their peers, but their refractive power is within the normal range. Their vision will return to normal with age, which means their visual function development is slightly delayed. Some children have problems with their refractive power, 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 go to the hospital for consultation and treatment in time.

Children with amblyopia, that is, whose corrected vision cannot reach the normal range, should wear glasses as early as possible. This is beneficial for treating amblyopia and promoting the development of visual function. Visual function develops mainly in childhood, especially when the child is 5-6 years old. After the age of 12, it is difficult for the visual function to return to normal.

Some children with strabismus should also wear glasses at an early age and try to correct the strabismus through the optical principles of glasses. Some children can correct their strabismus with glasses. For those who have no effect after wearing glasses for a period of time, surgical correction can be considered. Children whose corrected vision can reach the normal range should decide whether to wear glasses based on their eye usage. If their learning is affected, they have signs of visual fatigue, or they tilt their heads to look at things, they need to wear glasses.

A child's normal vision will change as they age, but if their vision is within the normal range, parents don't have to worry. However, if any unexpected situation occurs, you need to take your child to the hospital for examination. This is more reliable. Cooperate with the doctor's treatment. I hope every child grows up healthily.
