Does anyone know the answer to this (and whether it's been determined
experimentally):

     If an ultraviolet photon and an infrared photon strike the same
receptor in your eye at virtually the same place and time, does your
eye:
        1) Not respond because we aren't built for infrared and uv?
        2) Respond because the infrared and uv have an interference
           effect which results in what appears as a photon of
           some visible wavelength?

     Thanks in advance to anyone who does know,
