WebIn animal eyes, there are two types of cells, rods and cones. The rods are very sensitive to light, but cannot detect color (basically they work as black and white, also known as "greyscale"). The cones detect particular ranges of color. We have three types of cone cells, which birds have five. This makes birds very sensitive to minor changes ... WebThere are 2 types of photoreceptors in the retina: rods and cones. The rods are most sensitive to light and dark changes, shape and movement and contain only one type of light-sensitive pigment. Rods are not good for color vision. In a dim room, however, we use mainly our rods, but we are "color blind."

"WebThe photoreceptors of the eye's retina consist of rods and cones; rods serve vision in dim light, whereas cones serve high-resolution color vision in daylight. The first event in vision is the light-initiated isomerization of 11-cis-retinal, which is attached to rod or cone opsin, to all-trans-retinal. " - Rods enable what kind of vision
