    I want a simple definition of the term
    accommodative response sometimes spelled
    accommo-dative response.
    Is it as simple as how much the lens adjusts trying to focus?
    Thanks, Mike

    The term is used in the lighting article at,

    Well, they don't need a build-up of rhodopsin to see in bright light.
    Though it's always been my understanding that in normal illumination,
    rods are primarily responsible for motion detection.

    rods are only partially functionally under normal daylight
    conditions. the majority of vision in humans under those lighting
    conditions is considered to be contributed by cones which operate
    under much higher light levels.

    adaptation has much much more to do with other mechanisms than opsin
    content. there are neural pathways within the inner and outer
    plexiform layers of the retina, and within the CNS, that tune vision
    to the ambient lighting conditions
