Quizplus · Accepted Answer

Rods are responsible for peripheral vision and are more sensitive in low light conditions, which is why the teacher could detect movement in her peripheral vision. Cones are concentrated in the center of the retina and are responsible for color vision and detail. Phosphenes are the phenomenon of seeing light without light actually entering the eye, often experienced when rubbing the eyes. Stereocilia are not related to vision but are hairlike structures in the inner ear involved in hearing.
