Abstract
It has been known for many years that the human eyes are never quite motionless, even when steadily fixed at a point target (Adler and Fliegelmann, 1934). One particular component of the incessant motion is a very rapid tremor of the eyes. The amplitude of this tremor movement is usually less than 30 seconds of arc. This means that the amplitude of vibration of a point on the surface of the cornea is of the order of 0.001 mm. The frequency spectrum is concentrated mainly below 100 Hz, but sometimes extends to approximately 150 Hz. The tremor has horizontal (abduction-adduction), vertical (elevation-depression) and torsional components.
