Abstract

本发明涉及一种电子视力表系统，方向控制手柄(1)距离液晶电脑(3)为标准视力测试距离，方向控制手柄(1)与液晶电脑(3)通过连接线(2)连接，液晶电脑(3)按视力表要求，显示白底黑字，其字符大小按标准视力表进行显示，被测试人用手持方向控制手柄(1)指示字符方向，如正确，字符按标准缩小，直到被测试人出错，此时系统自动锁定视力结果，并通过液晶电脑(3)的屏幕显示结果。

Description

电子视力表系统
技术领域：
本发明涉及一种电子视力表系统，属于视力检查保健领域。
背景技术：         
当前，视力检查表采用纸质检查表，其检查需要专门人员配合才能进行，应用条件受光线等环境的制约。                           
发明内容：
本发明涉及一种电子视力表系统，以实现自动检测视力，并给定检查结果的视力检查系统。
为实现上述的目的，本发明采用如下技术方案：
一种电子视力表系统，包含：
方向控制手柄(1)、连接线(2)、液晶电脑(3)；如附图1所示。
以下结合附图，说明本发明的技术构造及方法：方向控制手柄(1)距离液晶电脑(3)为标准视力测试距离，方向控制手柄(1)与液晶电脑(3)通过连接线(2)连接，液晶电脑(3)按视力表要求，显示白底黑字，其字符大小按标准视力表进行显示，被测试人用手持方向控制手柄(1)指示字符方向，如正确，字符按标准缩小，直到被测试人出错，此时系统自动锁定视力结果，并通过液晶电脑(3)的屏幕显示结果。
本发明的有益效果：检查直观，使用方便，可自行检查，并自动给出结果。 
附图说明：
附图1是本发明的结构示意图
具体实施方式：
为了使本发明的技术方案更加清楚明白，以下结合附图和实施例，对本发明进一步详细说明，此处所描述的具体实例，仅仅用以解释本发明，并不用于限制本发明。
实施例：
请参阅附图1所示，方向控制手柄(1)距离液晶电脑(3)为标准视力测试距离，方向控制手柄(1)与液晶电脑(3)通过连接线(2)连接，液晶电脑(3)按视力表要求，显示白底黑字，其字符大小按标准视力表进行显示，被测试人用手持方向控制手柄(1)指示字符方向，如正确，字符按标准缩小，直到被测试人出错，此时系统自动锁定视力结果，并通过液晶电脑(3)的屏幕显示结果。
