The 1979 revision of the ANSI Z80.1 Ophthalmic Lens Standards resulted in rather significant changes affecting three areas of ophthalmic lens requirements: 1) central refractive characteristics, 2) prismatic characterstics, and 3) factors relating to the magnification properties of lenses. Based primarily on what an optical laboratory could consistently produce, the ANSI Ophthalmic Lens Sub-committee decided to widen some of the tolerances over those expressed in previous revisions. This paper attempts to show how these new tolerances relate to certain aspects of patient sensitivity to errors induced by ophthalmic lenses conforming with the new revision.
1979年美国国家标准学会（ANSI）Z80.1眼科镜片标准的修订导致了相当重大的变化，这些变化影响了眼科镜片要求的三个方面：1）中心屈光特性；2）棱镜特性；3）与镜片放大特性相关的因素。主要基于光学实验室能够稳定生产的情况，ANSI眼科镜片小组委员会决定放宽一些公差，使其比之前版本中的公差更宽。本文试图说明这些新公差与患者对符合新修订版的眼科镜片所引起误差的敏感度的某些方面之间的关系。
