Which photoreceptors are responsible for peripheral vision in dim light?

Rods are the photoreceptors responsible for peripheral vision in dim light. They are more sensitive to light than cones, making them particularly effective in low-light conditions. While cones are primarily involved in color vision and function best in bright light, rods allow us to detect movements and shapes in our peripheral vision, even when illumination is low. This is due to their abundance in the peripheral regions of the retina and their ability to detect light at lower intensities.

The other options, while they may relate to vision, do not specifically account for peripheral vision in dim light. Cones are less effective in dark conditions and focus on detail and color. Photoreceptors is a general term for both rods and cones and does not specify the type responsible for peripheral vision. Bipolar cells are part of the neural circuitry of the retina and play a role in processing visual information, but they do not directly function as photoreceptors. Therefore, rods are clearly identified as the key player in enabling peripheral vision in dim lighting conditions.
