眼动1是一种重要的生理活动。对于许多目的来说，主观地观察肉眼的眼球运动已经不够了。必须使用能够客观测量大范围和小角度眼球运动的仪器，长时间跟踪快速变化，并在各种实验和临床情况下使用。有三种基本方法可以客观地记录眼球运动（Duke-Elder 2）。第一种是通过直接连接到眼球的机械（或液压）系统。这种粗糙的方法已完全被另外两种方法所取代。记录眼睛转动的光学方法更为人所知。光源的角膜反射--第一个浦肯野像--被记录在移动的胶片上。这种方法有几个缺点。头部是固定的，通常强烈的眩光来自光源。
EYE MOVEMENTS 1 are an important physiological activity. For many purposes it is no longer sufficient to observe gross eye movements subjectively. Instruments must be used which can measure objectively eye movements over a large range and to a small angle, follow rapid changes for long stretches of time and be used under a variety of experimental and clinical situations. There are three fundamental methods by which eye movements can be objectively recorded (Duke-Elder 2 ). The first is by a mechanical (or hydraulic) system attached directly to the eyeball. This crude method has been completely supplanted by the other two. The optical method of recording rotations of the eyes is better known. Reflections from the cornea—the first Purkinje image—of a light source is recorded photographically on a moving film. There are several disadvantages to this procedure. The head is immobilized, and generally a strong glare comes from the light source.
