WebThe rods are the most numerous of the photoreceptors, some 120 million, and are the more sensitive than the cones. However, they are not sensitive to color. They are responsible for our dark-adapted, or scotopic, vision. The rods are incredibly efficient photoreceptors. More than one thousand times as sensitive as the cones, they can reportedly ...

WebThere are two types of photoreceptor cells in the retina: cones and rods. The cones are responsible for sharp color vision in daylight. The rods provide vision in dim light. Near the center of the retina is a small depression about 0.3 mm in diameter which is called the fovea.
