Which type of vision is predominantly for peripheral vision?

The type of vision that is predominantly responsible for peripheral vision is rods. Rods are photoreceptor cells located in the retina that are highly sensitive to light but do not detect color. They play a crucial role in night vision and are more numerous in the peripheral regions of the retina. This allows rods to detect motion and light in low-light conditions, making them essential for peripheral vision.

Cones, on the other hand, are more concentrated in the central portion of the retina and are responsible for color vision and visual acuity in well-lit conditions. Consequently, while they are important for detecting details straight ahead, they do not function as effectively for peripheral vision.

Night vision refers to the capability to see in low-light conditions, which is primarily mediated by the rods, but the term itself does not specify the peripheral aspect of vision.

Color vision pertains specifically to the ability to perceive different hues, which is primarily mediated by cones and is not relevant to the peripheral vision function. Thus, rods are the correct choice as they significantly contribute to peripheral vision in addition to aiding in visibility under low light.
