Contrast light and dark adaptation and include the role of the rods and cones.
What will be an ideal response?
Rods respond to low-intensity light that provides night and peripheral vision, while cones are bright-light, high-discrimination receptors that provide color vision. During light adaptation, rods are inactivated and as cones respond to the high-intensity light, high visual acuity results. In dark adaptation, cones do not function (visual acuity decreases) and rod function resumes when sufficient rhodopsin accumulates.
