为摆脱传统视力检查方法,适应于集体、临床和科研检测视力的需要,我们研制出微机控制视力检测仪,经730人(1460眼)对比检测证明,本仪器性能稳定,有较高的实用价值。视力检测仪的研制(一)视力检测仪由微机、视力表箱、方向指示杆和自动转换遮眼器构成:1.微机包括主机、监示器和打印机:通过电缆,主机与视力表箱、方向指示杆及自动转换遮眼器相连接。主机内贮有对不同检测对象(一般健康体检、临床和招收学员)要求编制的各种检测程序。随机出现视
In order to get rid of the traditional methods of visual acuity and adapt to the needs of collective, clinical and scientific research to detect visual acuity, we developed a computer-controlled visual acuity detector. The contrast test of 730 people (1460 eyes) proved that the instrument has stable performance and high practical value . Visual acuity detector (A) Visual acuity detector consists of a microcomputer, a sight box, a direction indicator and an automatic switchover eye shading device. 1. The microcomputer includes a host computer, a monitor and a printer: Direction indicator rod and automatic switch obscura connected. Host storage of different test objects (general health examination, clinical and recruit students) requirements of the preparation of a variety of testing procedures. Appear randomly
