fixational eye movement

Fixational eye movements are small, involuntary movements your eyes make when focusing on a single point. These tiny adjustments include tremors, drifts, and quick jerks called microsaccades. Their purpose is to prevent the image on your retina from fading or blurring by constantly refreshing the visual information. Without these movements, your brain might interpret the image as stationary and lose details. Although subtle, these movements are essential for maintaining a clear and stable view of stationary objects, allowing your visual system to function effectively during focused observation.
