Why should children wear glasses as early as possible when their eyesight decreases? There are several reasons for this: 1. The standard of normal children’s vision in one eye is as follows: 3 weeks old >= 0.5; 4 weeks old >= 0.6, 5-6 weeks old >= 0.7. 2. The causes of vision loss include: strabismus, myopia, astigmatism, farsightedness, etc. If we compare the development of eye vision with the development of the body, these causes are like malnutrition in childhood. If left untreated, when the child’s eyes mature, it will have a lifelong effect on the child’s vision, with mild retardation of vision development, or becoming intractable amblyopia. 3, currently known drugs or acupuncture, massage, massage, Chinese medicine and other treatments can not correct: strabismus, myopia, astigmatism, farsightedness. 4.Wearing glasses: Although they cannot correct myopia, astigmatism and farsightedness, they can improve corrected vision, help children see as clearly as possible during the developmental period, and keep up with the normal vision development of children of the same age, thus treating delayed vision development or amblyopia. 5, wearing glasses will not take off, or cause lifelong wearing glasses: after the amblyopia is cured, if the child’s degree is stable (generally aged 18 years or more), you can choose laser or other methods to remove glasses.
