摘要
光学中心单侧水平偏差是判断定配眼镜质量的重要指标之一。从业人员对现行国家标准GB 13511.1-2011《配装眼镜第1部分:单光多焦点》中“光学中心单侧水平偏差”的定义、检测方法和合格的判定存在一定争议。本文从实际情况出发,分析考核目的,采用自动影像测量仪测量,并与常规游标卡尺测量法进行对比,分析利弊。
The one-side optical center horizontal deviation is one of the important indicators for prescription assembled spectacles.Practitioners have certain disputes about the definition,testing methods,and eligibility determination of the"one-side optical center horizontal deviation"in the currently effective national standard GB 13511.1-2011"Assembled spectacles Part 1:Single-vision and multifocal".Based on the actual situation,this article analyzes the advantages and disadvantages of an auto video measuring machine from its assessment purpose,comparing with the conventional vernier caliper measurement method.
