Improvements in standards and technology go hand in hand. A careful study of standards as related to the state of the art always brings to light the need for improving technology. The study involved in revising the 1972 ANSI Z80.1 Standard for Ophthalmic Lenses has focused attention on several new and upcoming developments. These relate (1) to the predetermination of the edger setting, and the use of the perimeter of a lens, (2) the accurate control of centers, (3) the measurement of power and axis, and unwanted power in the periphery, (4) the use of computers in generating the shape of a lens and the location of the MRP, and (5) the standardization of shapes.
标准与技术的进步相辅相成。仔细研究与现有技术水平相关的标准总能揭示出改进技术的必要性。参与修订1972年美国国家标准学会（ANSI）眼科镜片Z80.1标准的研究，聚焦于几项新的和即将出现的发展。这些发展涉及：（1）磨边机设置的预先确定以及镜片周边的使用；（2）中心的精确控制；（3）度数和轴位的测量以及周边的有害度数；（4）利用计算机生成镜片形状和确定镜片顶点位置；（5）形状的标准化。
