Vision loss in children needs to be remedied in conjunction with the cause. Vision loss is usually related to irrational eye use, genetic factors, eye trauma, etc. Conservative or surgical treatments can be taken to control the condition. 1. Unreasonable eye use: If you look at the cell phone or computer for a long time, or do not like to go out and look at the distance, it may lead to vision loss. To remedy the problem, you need to improve your eye habits or participate in more outdoor sports. 2. Genetic factors: mainly through genetic inheritance, if the parents have low vision, the probability of the offspring is higher. In this case, it is generally recommended to wear eyeglasses to correct the situation, and after adulthood, you can choose to do myopia surgery, such as laser femtosecond surgery. 3. Ocular trauma: For example, eye contusion, fall, fist injury, etc., may affect vision and lead to vision loss. At present, trauma should be treated promptly. If there is subcutaneous bruising or conjunctival bleeding, etc., the bleeding needs to be stopped promptly. Children with vision loss need to go to the hospital as soon as possible for examination, and analyze the cause of low vision in conjunction with visual acuity testing and refraction testing, and then undergo formal treatment based on the diagnosis.
