Many myopic people will have a problem when wearing glasses, that is, the length of glasses. To put it simply, when do myopic patients need to wear glasses and when can they not wear glasses. Today, Wenzhou Wanrun Glasses Factory will discuss this problem together. The length and method of wearing glasses vary from person to person. We should first consider our own factors of myopia.




  Mild myopia and below: Mild myopia and medium high myopia take 300 degrees as the dividing point, and those below 300 degrees are mild myopia. Such people will not bring inconvenience to life, because they do not wear glasses, so they cannot always wear glasses. These people can wear glasses when engaged in near vision work, such as class, work and reading, while they do not need to wear glasses when engaged in other activities, such as running, walking and playing ball games.



  Moderate and severe myopia refers to people with myopia of more than 300 degrees. These people may need to wear glasses for a long time in their daily life. Otherwise, it may bring some inconvenience to daily life, which can be summarized by images: "Six parents 10 meters away cannot be identified, men and women 50 meters away cannot be identified, and humans and animals 100 meters away cannot be identified." Even when measuring vision, it is difficult to distinguish the stick!



  Some people think that wearing glasses for a long time will cause eyeball protrusion to become "goldfish eyes", which will affect the beauty. In fact, this is a misunderstanding. Exophthalmos is not related to the length of glasses, but is related to high myopia. As for the wearing time of glasses, I would like to remind you not to drive while wearing or changing glasses, because there is a running in period! In life, people with myopia may experience that when they first match glasses or change glasses, some people will feel dizzy, nauseous, and even dare not walk.



  If this happens, don't worry. This is actually normal. Users and new glasses need a running in period. Users can adapt to wearing glasses by gradually increasing the time each time they wear glasses. Generally speaking, 1-2 weeks can pass this running in period. Of course, if it is always difficult to adapt, it is also necessary to consider the problem of glasses themselves. Then, the lens should be further rechecked to check whether it meets the requirements of the doctor's prescription, and then check whether the pupil distance is consistent with the optical center of the lens.
