眼镜是治疗屈光不正的一种“药物”,它不仅要有良好的外观,更重要的是满足各项光学指标。九二年,本视光中心在温州市进行一次市场普查,共查5000副眼镜,不合格率竟高达93％,其根本原因就在于配镜人员缺乏系统的眼镜光学和视光学知识。因此,就存在的问题,经我多年的临床经验综合国内外资料,谈一点自己的看法,供参考。 一副合格的眼镜,其基础要有准确的验光,然后在配制过程中要注意以下的光学要求: (一)镜片的本身质量要合格,必须没有点状或条状疵病。检查方法:在60W的日光灯下以黑色屏幕为背景目测,必要时可用4—10倍放大镜检测,疵点直径≤0.2mm,范围≤1mm,条状疵病宽度≤0.025mm,范围≤6mm。要有良好的光洁度,无霉斑,霍光,物像无模糊,重影,扭曲变形。 (二)度数要准确,其上下差距不超过配镜处方的12度。测量方法:“+”字线中和法,镜片 Glasses are refractory to the treatment of a “drug”, it not only has a good appearance, more importantly, to meet the optical indicators. In 1992, the optical center conducted a market survey in Wenzhou City, a total of 5000 pairs of glasses were investigated, the failure rate was as high as 93%, the fundamental reason is that the lack of systematic optical lens optical and optical knowledge. Therefore, on the existing problems, I have many years of clinical experience combined with domestic and foreign information, to talk about their own views for reference. A pair of qualified glasses, the basis of accurate optometry, and then in the preparation process should pay attention to the following optical requirements: (A) the quality of the lens to be qualified, there must be no punctate or stripe defects. Inspection methods: 60W fluorescent lamp with black screen as the background visual inspection, if necessary, available 4-10 times magnifying glass detection, defect diameter ≤ 0.2mm, range ≤ 1mm, strip defect width ≤ 0.025mm, the scope of ≤ 6mm. Have a good finish, no mildew, Huo Guang, the image without blur, ghosting, distortion. (B) the degree should be accurate, the difference between the upper and lower prescription does not exceed 12 degrees. Measurement method: “+” word line and method, lens
