Final answer:
The two types of receptors found in the retina are rods and cones; rods are for low-light and peripheral vision while cones are for bright light and color vision.
Step-by-step explanation:
Types of Receptors in the Retina
The retina contains two types of photoreceptors: rods and cones. Rods are highly sensitive to light and are essential for peripheral and nighttime vision, allowing us to see in low-light conditions. They can't detect colors, only shades of gray. Conversely, cones respond to bright light and are crucial for daytime vision and the perception of color. Cones are primarily found in the central part of the retina, in an area known as the fovea. The human retina houses approximately 120 million rods and three types of cones that differ in sensitivity to various wavelengths, enabling color vision.
