Does a 3-year-old child with a vision of 0.5 need treatment? What are the priorities for parents to pay attention to their children's vision?

Nowadays, televisions, mobile phones and computers have become indispensable to every household. In addition, children learn to read for a long time, which causes a large eye load and increases the risk of myopia. Some parents take their children to the hospital to check their eyesight on a regular basis. Once they find that their vision is 0.5, they are very anxious. Do they need treatment in this case? Does a 3-year-old child with a vision of 0.5 need treatment? A 3-year-old child with a visual acuity of 0.5 should not be overly concerned or over-treated. According to the normal development process of the eyes, there should be 200 degrees of hyperopia at the age of 3, which is called hyperopia reserve in medicine, so the visual acuity of 0.5 is not necessarily a manifestation of morbidity, but it needs to be diagnosed by an ophthalmologist. Parents should pay more attention to the changes in children's vision and grasp the golden period of vision development. What are the key points of paying attention to children's vision? 1. Take the child to a regular hospital for dilated optometry after the age of three to check the hyperopia reserve. Under normal circumstances, 3 years old, 8 years old and 12 years old have hyperopia of 200 degrees, 150 degrees and 100 degrees respectively. If the hyperopia is not enough in the corresponding age group, for example, the visual acuity reaches 1.0 at the age of three, indicating that the hyperopia reserve is insufficient, and the risk of myopia will be high in the future. Therefore, regular inspections and early intervention should be performed. 2. When looking at the same object with the refractive difference between the left and right eyes, the distance from the left and right eyes to the target is the same, ensuring coordination when looking at distant and near objects. If the child's left eye and right eye diopter is greater than 100 degrees, it is necessary to seek medical attention as soon as possible. 3. Methods of measuring visual acuity At present, there are two methods for measuring visual acuity, one is the vision chart with a distance of 2.5 meters, and the other is the vision chart with a distance of 5 meters. The common point is to look at the size of the letters on the vision chart. Check distance changes to assess myopia. However, the results of the two measurements are different and cannot be mixed. How to prevent myopia in children? 1. Children under the age of 6 should not watch electronic products for more than 20 minutes, and children aged 6 to 12 should not watch electronic products for more than 30 minutes. 2. Look from a distance. After using your eyes for 20 to 30 minutes, you need to look far away. The farther you can see, the better. It can relax your eyes, relieve eye fatigue, and prevent myopia. 3. Exercise more and have at least 1 to 2 hours of outdoor activities every day, which can relax the ciliary muscles of the eyes, prevent myopia or prevent myopia from deepening. Warm reminders have repeatedly reminded children not to tilt their heads when looking at objects, which can increase the load on the left and right eyes, cause visual fatigue in a short period of time, and cause a large difference in the refraction of the left and right eyes. In addition, eat more yellow-green foods, such as broccoli, egg yolks and corn, carrots and tomatoes, which contain a variety of vitamins and lutein, which can protect eyesight; remind children to pay attention to eye hygiene and do not rub with hands.
