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 have their eyesight adjusted for low vision, low vision that significantly affects learning, work, and life, and symptoms such as visual fatigue, dizziness, and headaches. Before the age of 6, children 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 wait 20 days for the pupil to return to normal before conducting a trial test; students between the ages of 12 and 18 can undergo a rapid pupil examination, and the next day the pupil returns to normal after the trial test; after the age of 18, the pupil may not be dilated and examined, and the trial test is 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 may opt for refractive surgery for correction if required for work and life after a rigorous examination by an ophthalmologist.
