WebCells in the eye called rods and cones are primarily responsible for detecting light. They send signals to the brain through retinal ganglion cells (RGCs) so the brain can form our perception of images. But our eyes do more than help create images of our surroundings.

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. Cones require a lot more light and they are used to see color.
