Active vision: How you look reflects what you are looking for

While we fixate an object, our eyes are never stationary but constantly drifting, with miniature movements traditionally thought to be random and involuntary. A new study shows that the orientation of such drift in humans is actually not random but is influenced by the task demands to improve performance.

When fixating an object, our eyes do not remain stationary but constantly drift, and it was previously believed that this drift was random and involuntary. However, a recent study has found that the direction of eye drift is not random but is influenced by task demands to enhance performance.
