After a child is born, their vision continues to develop. In order to understand whether their vision development is healthy and good, parents need to regularly take their children to the hospital for vision check ups. Recently, a parent took their child to the hospital for vision check ups, and the results showed 4.6. Therefore, parents want to know if their three-year-old child's vision of 4.6 needs treatment?
From birth to one and a half years old, a child's vision generally reaches a level of 0.4. At two years old, it can reach a level of 0.5. At three years old, vision drops to a level of 0.6. At four years old, vision approaches a level of 0.8. By five years old, vision is approximately 1.0. Therefore, it can be concluded that a three-year-old child's vision of 4.6 is abnormal and requires treatment.
The visual acuity of a three-year-old child is 4.6, which is approximately 200 to 300 degrees in commonly used units. It should be considered to be related to myopia, which is a type of refractive error. It is recommended that parents take their children to the hospital for further examination as soon as possible. If it is determined to be a myopia problem, it can be corrected by wearing appropriate glasses.
Parents also need to pay attention to their children's eye usage time and distance, avoiding prolonged or close reading, television, mobile phones, tablets, etc., to prevent children from using their eyes excessively and causing eye fatigue. It is best to take a break every 15 minutes, look at the surrounding green plants, and avoid letting children live and study in areas with insufficient light. They should also eat more foods that are good for their eyes in their diet.
