    As for night vision and day vision, the explanation on this list in October was not accurate. Indeed, because of diffraction, the resolution of the human eye is lower in very bright sunlight than in medium lighting.
     
     
    This may well be true (I do not know) but I can think of one example at least where it might seem not to be so, a surgeon will use a VERY bright tightly collomated beam...maybe that is to enhance contrast or something?-Ken
