Abstract
一种人眼开车指数测量装置，它包括测试视标和眩光光源，其特征是模拟交通信号的测试视标连接眩光光源。本实用新型的技术效果是：1、该装置能够模拟晚上开车时的前方来车的眩光；2、能够给出人眼的开车指数。
Description
技术领域
本实用新型涉及一种测量装置，尤其涉及一种人眼开车指数测量装置。
背景技术
近年来，随着眼病患者对视觉质量要求的不断提高，白内障手术和屈光手术等眼科外科手术成为不少眼科患者的选择。但是，给病人实施眼科外科手术的同时，容易引起术后高级像差的增加，从而使部分病人晚上视觉出现眩光、单眼复视、星状像等临床视觉症状，即晚上的视觉质量明显低于白天的视觉质量。如果出现这些症状的司机朋友晚上开车，发生交通事故的可能性会大大增加。因此，需要一定的装置来测量司机朋友的开车指数，来评估他们在晚上开车的安全性，从而减少交通事故的发生。
发明内容
本实用新型的目的在于提供了一种人眼开车指数测量装置，该测量装置通过模拟红绿灯的判读评估人眼识别红绿灯的能力，通过模拟绿灯的箭头方向评估人眼识别汽车转向信号的能力，通过模拟眩光来评估人眼晚上时眩光状态下对交通信号灯的判读能力。
本实用新型是这样来实现的，它包括测试视标和眩光光源，其特征是模拟交通信号的测试视标连接眩光光源。使用时，计算机系统控制LED显示屏产生带有转向方向的测试视标，高亮光源用于模拟眩光测试，测试软件部分包括测试视标的产生、测量数据的记录和测量结果的分析并给出人眼开车指数。
本实用新型的技术效果是：1、该装置能够模拟晚上开车时的前方来车的眩光；2、能够给出人眼的开车指数。
附图说明
图1为本实用新型的结构示意图。
在图中，1、测试视标 2、眩光光源
具体实施方式
如图1所示，本实用新型是这样来实现的，它包括由LED显示屏产生的测试视标1、眩光光源2，其特征是模拟交通信号的测试视标1通过计算机控制由LED显示屏模拟产生交通红绿灯、表示行车方向的绿灯箭头和常用的交通标识，然后由被测试者判读测试视标；通过眩光光源2模拟被测试者开车时迎面行使汽车的远照灯，它们由一对卤素灯组成；测试软件由视标产生部分、数据记录部分和数据分析部分组成。测试视标1提供有效视标、根据被测试者的判读结果记录测量结果，眩光光源2和测试视标1同时使用时，可以模拟被测试者在眩光状态下对测试视标的判读，从而得到被测试者在眩光状态下的开车指数。
