Abstract

斜视测定仪,凹面镜2的镜底3的曲率与眼球角膜的曲率一致,上伞沿4的曲率与巩膜的曲率一致。在凹面镜的内表面镶固有定位格层5,定位格层由黑白相间的网格组成,黑格6不透光,白格7透光。光源1镶固在凹面镜底的中心处。本仪器可用于测定眼视力的斜度,当网格中心格点或十字形光源的中心偏移落在眼球上时,根据偏移格数的多少,就可较准确地测出斜视的度数,给视力矫正提供了方便。

Description

斜视测定仪
斜视测定仪属于检查眼睛视力的仪器。
现有检查眼睛视力斜度的器具一般只能定性。而不易准确定量,这必然给视力矫正工作带来麻烦。
本实用新型的目的是研制一种斜视测定仪,用该仪器检查视力不但能定性。而且能很容易地定量。给后续的视力矫正工作提供了方便条件。
本实用新型由光源、凹面镜组成。凹面镜由两部分组成,一部分是镜底。另一部分是镜的上伞沿。镜底的曲率与眼球角膜的曲率一致,上伞沿的曲率与眼球巩膜的曲率一致。在凹面镜的内表面又镶固有定位格层,定位格由黑白相间的网格组成,黑格不透光。白格透光。光源镶固在凹面底的中心处。
本实用新型可用于测定人眼视力斜度,当网格中心格点或十字形光源的中心偏移落在眼球上时,根据偏移格数的多少马上就可测定出斜视的度数。给视力矫正工作提供了较为准确的数据,方便了医护人员和患者。
图1是本实用新型整体结构主视图,图2是整体结构的俯视图,图3是实施例二的结构示意图。
实施例一:本实施例由光源1、凹面镜2组成。凹面镜2由镜底3、上伞沿4组成。镜底3的曲率与眼球角膜的曲率一致,上伞沿4的曲率与眼球巩膜的曲率一致。在凹面镜2的内表面镶固有定位格层5,定位格层5由黑白相间的网格组成。黑格6不透光,白格7透光。光源1为普通的白炽灯泡。白炽灯泡1镶固在凹面镜底3的中心处。
实施例二:本实施例的凹面镜2与实施例一相同,但取消了凹面镜2上的定位格层5。光源1由十字形日光灯8担任,十字形日光灯8由长管9、短管10组成,长管9与短管10在各自中心点处相交。在交点处有一不透光的黑圆球11,在长管9上均匀分布有数个比短管10还短的定位光源12。十字形日光灯8的短管10的曲率与凹面镜2的镜底3的曲率相同,长管9处于镜底3部分的曲率与镜底3的曲率也相同,长管9处于上伞沿4都分的曲率与上伞沿4的曲率相同。十字形日光灯8镶固在凹面镜2的内表面上。
