Question

Quizplus · Accepted Answer

The duplicity theory of vision posits that the eye has two distinct types of photoreceptors: rods and cones, which serve different functions. Rods are responsible for vision at low light levels (scotopic vision), while cones are responsible for color vision and detail at higher light levels (photopic vision). This theory highlights the functional and anatomical differences between these two systems within the eye.
