Verified step by step guidance

Begin by understanding the function of photoreceptors in the eye. Photoreceptors are specialized cells in the retina that respond to light and are crucial for vision.

Identify the two main types of photoreceptors: rods and cones. Rods are responsible for vision in low light conditions and peripheral vision, while cones are responsible for color vision and visual acuity in bright light.

Consider the location and distribution of these photoreceptors in the retina. Rods are more numerous and are distributed throughout the retina, except in the fovea, which is densely packed with cones.

Recognize that peripheral vision is primarily mediated by rods due to their widespread distribution in the retina and their ability to function in low light conditions.

Conclude that rods are the photoreceptors primarily responsible for peripheral vision, as they are adapted to detect motion and provide vision in dim lighting, which is typical of peripheral vision.
