When you get your glasses, you should first check the quality of the glasses: the lenses should be polished, transparent, free of bubbles and particles, uniform texture, no hawklight, no streaks. Whether the lens legs are attached to the outer ear round and to the head, the elasticity should be moderate to avoid slippage. Also should pay attention to the lens and the eye distance is appropriate. The lens and the frontal surface should be at an angle of 10~150, and the lens should be perpendicular to the visual axis of the eye. In the early stage of wearing glasses, some patients can’t adapt to the difference between glasses and physical objects because they haven’t worn glasses in the past, and they may become dizzy, dizzy and even afraid to walk. If this is the case, patients can wear glasses for a short period of time, and then gradually extend the time to adapt. If the patient can not adapt to the prescription for a long time, the glasses should be considered to be different from the prescription. If the patient can’t adapt to the prescription for a long time, he/she should consider whether the prescription is wrong or not. After getting the right glasses, whether it is necessary to wear them often, this is also a question often asked by patients. This question should be treated according to the refractive power of the eye, refractive nature, age and nature of work and other different situations. For young patients above -2.00D, glasses should be worn frequently; however, patients with mild myopia, such as -1.00~-2.00D, need to wear glasses when looking at a distance, but can be left out when looking at a close distance. For myopic children with strabismus or amblyopia should often wear glasses to correct the eye position and restore vision, otherwise, the affected children in close reading and writing or operation, causing excessive convergence, can contribute to the development of myopia. 40 years of age or older, low myopia patients can work at close range without wearing glasses, but still need to wear when looking at a distance; such as people who work mainly at close range, the requirement to wear glasses is not very urgent, on the contrary, even if the degree of myopia Not deep, but also need to wear moderate glasses often. After wearing myopia glasses, you should pay attention to eye hygiene, which plays an important role in preventing the development of myopia. Some students mistakenly believe that myopia will not deepen if they wear glasses, so they abuse their eyesight and still do not pay attention to eye hygiene, causing myopia to develop and deepen. The protection of glasses is also very important. In order to maintain the transparency of the lenses, do not wipe them too much on a regular basis. When wiping, it is possible to use alcohol cotton balls or flannel, but not a coarse cloth, otherwise the lenses will be worn out. If the glasses are not used, they should be stored properly in the glasses case so as not to crush them. Lenses should also not be put together with acid and alkali substances to avoid deterioration and affect transparency. Eyeglass frames, especially plastic frames, are easily deformed and combustible, so do not subject the frames to high temperatures or to. When doing strenuous activities, you should also pay attention to use the rope to fix the glasses in the head, to avoid activities when the glasses fall off. In short, myopic patients should master the correct use of their own glasses, to avoid wearing improperly caused by myopia and all kinds of discomfort, so as to avoid damage to glasses and affect learning, work and life.
