The glasses are not broken and the degree is enough. Why change them?

Abstract: children and adolescents with myopia need to go to the hospital for reexamination on time and change their glasses regularly. Children and adolescents are in the stage of growth and development, which is the peak of eye use, and the degree changes very quickly. Myopia tends to deepen due to long-time close eye use., In fact, many people have no concept of the service life of frame glasses. Glasses are not bad, and the degree is enough. Many people wear a pair of glasses with oxidized yellow lenses for many years. No wonder their eyes are always tired! Most people only consider changing their glasses when they can’t see clearly, the frame is broken or obviously uncomfortable. However, if the glasses are not broken and the degree is enough, they should be replaced in time according to the situation., The lenses will oxidize and turn yellow after long-term use, and the clarity and light transmittance will be reduced. In addition, the resin lenses have poor wear resistance and will be worn and scratched in varying degrees, which will cause eye fatigue and aggravate myopia in severe cases., Glasses for children and adolescents: they need to go to the eye hospital for reexamination every six months. After glasses for children and adolescents with myopia, they need to go to the hospital for reexamination on time and replace glasses regularly. Children and adolescents are in the stage of growth and development, which is the peak of eye use, and the degree changes very quickly. Myopia tends to deepen due to long-time close eye use. Children and teenagers need to go to a professional eye hospital for reexamination in half a year. If glasses are no longer suitable for children, they should replace them in time., Adult glasses: generally, they are replaced once a year or two. Due to the relatively stable degree, the frequency and initiative of adult optometry are far lower than those of children and teenagers. Even some adults are lazy to do optometry and just match glasses directly according to the original degree of glasses. These are not correct practices. Adults also need medical optometry to wear glasses. Adults generally change glasses once a year to two years.,
