Should I wear glasses all the time? This problem normal may be to say myopia glasses, after matching myopia glasses, moderate myopia and high myopia, had better be to see far, see near to want to wear. If low myopia, can be to see far when wear, see near when can not wear. 300 degrees less than call low myopia, 300-600 degrees call moderate myopia, 600 degrees above call high myopia, because moderate and high myopia. If you don't wear it continuously, the adjustment of your eyes will be easy to spasm, so it is easy to cause myopia to deepen. There is also a category of presbyopic glasses, presbyopic glasses is normal to see near when wearing, see far when not wearing, if there is visual fatigue, belong to hyperopia and presbyopic. In this case, see far wear a pair, see near wear a pair, with the increase of age, normal 40 years old or older adjustment power is poor, you may wear two pairs of glasses.
