The first reason is: parents inherit. Hereditary myopia is usually manifested in adolescence, that is, when children go to junior high school, parents with more serious degrees will behave earlier.

The second reason is: excessive use of eyes. Excessive eye fatigue can lead to myopia in children, and children who read more books and watch more electronic products are more likely to be nearsighted. Remember to relax your eyes properly.

The third reason is to modify the face. Frame glasses don't all have lenses, they can just be a frame. The spectacle frame can make the face look slender and cover up the defects of the eye shape. Sometimes you can wear different styles of clothes to make people more knowledgeable.
