Optokinetic nystagmus is the motor response of the eye to a continuously moving pattern that has contrasting elements. The OKN consists of slow phases that reduce or prevent movement of the image across the retina, and of fast phases that reset the eyes to succeeding elements of the pattern.

An optokinetic stimulus can be generated either by movement of the surrounding environment, or by movement of the observer in a stationary environment. Thus, OKN will be stimulated when the observer directs visual attention onto a passing railroad train, but will also be stimulated in a passenger on the train who is viewing the passing scene through a window.
