WebMar 1, 2024 · When the light is detected at a low level for 20 minutes or so, the body starts producing rhodopsin and night vision starts setting in. The other contributor to night vision is the pupil opening, but that goes to maximum within a few minutes of dark exposure. The big player in night vision is rhodopsin, and that takes from 20 to 40 minutes for ...
