WebbThe eye’s inner layer is composed of the retina: thin tissue that contains blood vessels and light-sensitive photoreceptor cells called rods and cones. Every human eye contains about 120 million rods and 7 million cones. The rods are very sensitive to low-level light, but they cannot distinguish color.
