在验光镜片组中，球镜片、柱镜片和棱镜片是最主要、最常用、并且数量最多的三种镜片。本文对《验光镜片组》（JJG579－88）检定规程中，这三种镜片的检定方法提出改进。一、球镜片检定方法的改进按照检定规程规定，球镜片有二项技术要求，即顶焦度偏差和光学中心位移。顶焦度 In the optometry lens group, the ball lens, column lens and prism film is the most important, most commonly used, and the largest number of the three lenses. This article on the “refraction lens set” (JJG579-88) test procedures, the three lens test methods proposed improvements. First, the ball lens test method to improve According to test procedures, the ball lens has two technical requirements, namely, the deviation of the vertex power and optical center displacement.
