The determination of close visual acuity is done accurately if the vision exam at a distance of 40 cm is standardized and if an exact estimation of the near visual acuity for professional activities of normal people and people with bad visual acuity can be made. The model of an optotype for near vision, Snellen metric type, using the Jaeger notation from 1 to 16 and also the standardized point system from 3 to 36, is presented. A professional selection of people with bad visual acuity after near visual exam is also presented.
如果40厘米距离的视力检查标准化，并且能够准确估计正常人和视力不佳者进行专业活动时的近视力，那么近视力的测定就能准确完成。本文介绍了一种近视力视标模型，即斯内伦公制视标，它使用从1到16的耶格符号以及从3到36的标准化点数系统。本文还介绍了在近视力检查后对视力不佳者进行专业筛选的方法。
