Abstract

瞳距镜实用新型是一项验光配镜的设备,是一个特制的眼镜,一眼为带孔(直径2mm)的黑镜片,另眼为带刻度的平光镜片,被检者戴上此镜,检查者即可测出瞳距。制作简单,使用方便。

Description

本实用新型涉及验光配镜问题。
本实用新型的目的:在验光配镜中测定瞳距很重要,常因瞳距不准确而致配好的眼镜不能戴用,一般常用米尺测定瞳距不甚方便,有时不准确,为此设计瞳距镜,以更好地测定瞳距为目的。
本实用新型是用普通眼镜框,右侧装上中心带小孔的黑色镜片,小孔直径为2毫米,左侧装上光学平光镜片,在该平片上划有垂直的红线条刻度,与对侧小孔之距为55、56、57、58、59、60、61、62、63、64、65、66、67、68、69、70、71、72、73、74、75、毫米,刻度间距为1毫米,镜框的鼻垫是活动的,位于中心水平线上,镜腿是直的,耳点后变宽。这样的镜框可以反转戴用,黑色小孔镜可以戴在右眼上,反过来可以戴在左眼上。
附图:中心带小孔的黑镜片(1)和带刻度的平光镜片(2)。
本实用新型的使用方法:将瞳距镜给被检者戴上,让被检者右眼由黑片小孔内向前注视,检查者用右眼观看被检者左眼瞳孔中心在镜片上的刻度,即是被检者的瞳距。如被检者的右眼有病不能注视,将瞳距镜反转过来让被检者左眼由黑镜片的小孔内向前注视,检查者用左眼观看被检者的右眼瞳孔中心在镜片上的刻度,即被检者的瞳距,使用方便而准确。
