If a child’s naked eye vision is poor or the degree of myopia exceeds 200 degrees, it is recommended to wear glasses all the time to correct their vision. If a child’s naked eye vision is good, or the degree of myopia is less than 200 degrees, generally do not need to wear glasses all the time, you can wear glasses when you need them, such as: wear glasses in class when you look at the blackboard, and you can take off the glasses when you are reading close up. Therefore, whether children need to wear myopia glasses all the time mainly depends on the child’s naked eye vision and myopia and other factors. It is recommended that children with myopia should go to the hospital as soon as possible for standardized optometry and other examinations, and strictly follow the doctor’s instructions, and wear glasses in time to slow down the development of myopia if necessary.
