There is a concern about depth perception with night vision goggles (NVGs). We measured judgments involving depth perception in laboratory and field conditions. When participants judged absolute distance, or collision, in a laboratory, results indicated that objects can appear closer with NVGs than with unaided vision, and underestimations of distance were greater with smaller distances. When participants were transported in a car and judged when to turn a vehicle to avoid collision with a simulated wall, there was no difference between goggle and unaided vision. Effects of NVGs on depth perception may be specific to task and viewing conditions.
