From the video, sometimes there were as few as 5 - 10 photons from the reflector, which may have been difficult for the eye to pick up, but other times there were more and at those times the eye could easily have picked up the flash of light. |
As noted earlier, 5-9 photons within 100 ms is sufficient for the human brain to register the light.
