The weakest pulse of light a human can detect sends about 100 photons through the pupil and produces 10–20 rhodopsin isomerizations in a small retinal area1,2. It has been postulated3 that we cannot see single photons because of a retinal noise arising from randomly occurring thermal isomerizations. Direct recordings have since demonstrated the existence of electrical 'dark' rod events indistinguishable from photoisomerization signals4–6. Their mean rate of occurrence is roughly consistent with… CONTINUE READING
