Thousand-yard stare

The thousand-yard stare (also referred to as two-thousand-yard stare) is the blank, unfocused gaze of people experiencing dissociation due to acute stress or traumatic events. The phrase was originally used to describe war combatants and the post-traumatic stress they exhibited but is now also used to refer to an unfocused gaze observed in people under any stressful situation, or in people with certain mental health conditions.

The thousand-yard stare is often associated with shell shock, combat stress reaction, and other trauma-related mental health conditions.
