WebJan 6, 2010 · 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. The human eye has over 100 million rod cells.
