Currently, the most effective solutions for refractive errors are frames, corneal contact lenses and refractive surgery to correct them. There are different solutions for different age groups, different refractive states and different needs. Children with myopia, hyperopia, astigmatism, and presbyopia should get an optometrical prescription if their vision is low, if they have symptoms that significantly affect their studies, work, and life, or if they have significant visual fatigue, dizziness, and headaches. Children before the age of 6 years old are mostly farsighted, teenagers are mostly nearsighted, and the elderly are mostly presbyopic or mixed myopic, farsighted or astigmatic. After examination by professional ophthalmologists and optometrists, low, moderate or even high refractive errors can be corrected or not according to the specific situation, and if the bare eye vision is poor and requires squinting to see clearly, which can be squinted, glasses or refractive surgery are needed. The general principle is that children before the age of 12 should first undergo a 1% atropine pupil examination, and then undergo a trial test after 20 days of normal pupil recovery; students between the ages of 12 and 18 can undergo a rapid pupil examination, and then undergo a trial test after normal pupil recovery the next day; after the age of 18, no pupil examination can be done, and the trial test can be conducted directly after the examination. Myopia in adolescents is mainly the most economical and preferred solution with ordinary frames. If myopia deepens too quickly, special methods are needed: such as corneal shaping lenses, to control the rapid growth of myopia. Adults over the age of 18 can opt for refractive surgery for correction after a rigorous examination by an ophthalmologist if they need it for work and life. Non-surgical methods: frame glasses: regular frames, bifocals or progressive multifocal lenses for adolescents.
