In the reception of ophthalmology outpatients, often patients feel dizziness, eye pain and other uncomfortable symptoms after wearing new prescription glasses to seek help, after careful examination, found that the problem is a lot of wear in the inappropriate glasses! Why in the hospital optometry try to wear glasses in the process of no discomfort symptoms, but after the prescription patients feel uncomfortable? After careful questioning, we learned that some friends in the hospital ophthalmology department to get prescription, quietly leave, go to the hospital outside of some eyeglasses store with glasses, they think that the glasses are like other goods, as long as you can see clearly, where to buy can be. They think that eyeglasses are just like other commodities, as long as they can see clearly, they can buy them anywhere. Unbeknownst to them, in addition to the cumbersome process of medical optometry, the assembly of eyeglasses is also very important in the fitting of eyeglasses. In fact, in a sense, glasses are a kind of “optical medicine”, a good pair of glasses should have a corrective effect on vision, but also harmless to the eyes, just stay in the clear vision is not enough. A good pair of eyeglasses requires three factors: first, accurate optometry, second, quality assurance of lenses and frames, and third, quality assurance of production. Among them, optometry is the most critical and the most complicated, the least easy to do well, which is the reason why some people get prescription after the hospital optometry and leave. But they often ignore the second and third factors. Eyeglasses fitting is also a high-tech technology, which requires operators to have rich knowledge of ophthalmology and be able to use high-tech equipments to make personalized and humanized eyeglasses according to different prescriptions. If non-automatic equipment is used in the production process, a slight error on the part of the operator will cause serious discomfort to the wearer. In the process of customization, it is necessary to polish, grind the edge, open the groove, set the pupil distance, pupil height, etc., and in the process of processing, the technical level of the assembly technician is very high, and at last, it is necessary to re-adjust the frame, and in the last link, the quality inspector will also make use of the full-automatic focus meter to carry out the quality inspection according to the data listed in the prescription, and then hand over to the wearer after there is no error. Therefore, the birth of a pair of suitable glasses is the crystallization of the hard work of optometrists and eyeglasses fitting technicians, which should be cherished by us.
