Visual function screening method

The invention provides a visual function screening method, which belongs to the field of visual function testing, integrates vision examination, refraction examination and visual function examination into one device, can simulate distant vision examination in a limited space, reduces the transportation cost of screening equipment and the requirement on screening labor, and improves the screening efficiency. And the time for the students to switch among different devices is saved, so that campus screening is more convenient. The device is small in occupied space and high in flexibility, and the screening efficiency is improved. 本发明提供了一种视功能筛查方法，属于视觉功能测试领域，将视力检查、屈光检查、视功能检查融合到一台设备中，可以在有限的空间内模拟远视力检查，降低了筛查设备的运输成本以及对于筛查工作人力的需求，并且节省了学生在不同设备之间转换的时间，让校园筛查更加方便。本发明占用空间小，灵活度高，而且提升筛查的效率。
