GENERAL HISTOLOGY

Detailed explanation-1: -There are two types of photoreceptors involved in sight: rods and cones . Rods work at very low levels of light. We use these for night vision because only a few bits of light (photons) can activate a rod. Rods don’t help with color vision, which is why at night, we see everything in a gray scale.

Detailed explanation-2: -There are two types of photoreceptors: rods and cones. Rods are more sensitive to light, making them primarily responsible for vision in low-lighting conditions like at night. Cones are less sensitive to light and are most active in daylight conditions. The cones are also responsible for color vision.

Detailed explanation-3: -Photoreceptor function and types While cone photoreceptors detect color through bright light, rod photoreceptors are sensitive to low-light levels. Rods aid in night vision and identifying black and white hues.

Detailed explanation-4: -Cones are less sensitive to light than the rod cells in the retina (which support vision at low light levels), but allow the perception of color.
