Question

Compare and contrast the photopic and scotopic visual systems. a) Photopic vision is for color and detail, scotopic vision is for low-light and movement b) Photopic vision is for low-light and movement, scotopic vision is for color and detail c) Photopic vision is for peripheral vision, scotopic vision is for central vision d) Photopic vision is for night vision, scotopic vision is for day vision

Answer 1

a) Photopic vision is for color and detail, scotopic vision is for low-light and movement

Explanation: Photopic vision occurs in well-lit conditions and is responsible for color vision and detecting fine details. It relies on cone cells, which are concentrated in the fovea, for processing visual information.

Scotopic vision, on the other hand, operates in low-light conditions and is responsible for detecting motion and providing vision in dim light. Scotopic vision primarily involves rod cells, which are more sensitive to low levels of light than cone cells, allowing them to function better in low-light situations.
