How bad is 0.1?

The eye is an important sensory organ, and more than 90% of the information people get from the outside world comes from the eye. Children are in the stage of growth and development. Vision varies at different ages. For normal people, the vision standard is 1.0. If the vision is lower than 1.0, the first optometry should be performed. If the vision can be corrected, it proves that there is refractive error. The problem is not serious. It is OK to wear glasses. If it cannot be completely corrected, it means that in addition to refractive error, there are other problems in the eye, such as cataracts, fundus diseases, etc., so once the vision is reduced, it is necessary to go to the hospital in time.
