Abstract : Recovery of dark adapted acuity after the use of a night vision system was observed in two experiments within a flight simulation facility. The users of these two systems gave up about one log cycle in dark adaptation (luminance required) to gain about one log cycle in viewing objects 5 to 10 minutes or larger. One hundred percent recovery of rod dark adaptation required from 3.0 to 4.2 minutes. Because of their target brightness sensitivity, color characteristics and acuity ranges, these systems can be appropriately compared with human unaided dark adapted rod vision. (Author)
