key term - Rods

Definition

Rods are photoreceptor cells located in the retina that are responsible for detecting motion and dim light. They do not contribute significantly to color vision but play a crucial role in peripheral vision.

Dark Adaptation: The process by which rods and cones adjust their sensitivity to light when transitioning from bright to dim lighting conditions.

Peripheral Vision:

The ability to see objects outside the direct line of vision. Rods are highly concentrated in the peripheral regions of the retina, enhancing our peripheral vision.

Scotopic Vision: The type of vision mediated primarily by rods under low-light conditions where color perception is limited.
