The eyes are suddenly a little nearsighted, this is impossible, it can only mean a problem, is that the eyes have always existed before myopia, but they did not pay attention to it, only to find their eyes do not see things clearly by chance, so it is described as the eyes are suddenly a little nearsighted. In this case, the first thing to do is to go to the hospital for a detailed optometric examination, and in the case of children, it is generally recommended that dilated optometry be performed, so that the eye’s own adjustment function can be removed and the refractive state of the eye can be accurately reflected. If, after the examination, the eyes are indeed myopic and have caused vision loss, glasses should be worn early to improve corrective vision and maintain clear visual quality. If you do not want to wear frame glasses, you can also choose corneal contact lenses, which are also very effective.
