Microsaccades

Microsaccades are a type of a fixational eye movement that are small, jerk-like eye motions that are associated with fixed vision (looking at something for more than a sew seconds). Their actual function is not completely understood but it has been proposed to be a mechanism by which vision makes small corrections for drift. Research continues in the fields of neuroscience and psychophysics to further discern the functions of these eye motions.
