By two months, a baby can distinguish between many colors such as red, blue, and, green. Their visual acuity and sensitivity to contrast has improved considerably, but is still about twenty times less developed than adults. These immaturities have to do primarily with the immature neurons in the eyes. A newborn's rods are fairly mature making it easy to see crude black and white images but a newborn's cones, which decipher fine lines and color, are not. An adult employs over fifty thousand cones in the fovea, a small area on the retina, to do most seeing. But the newborn's fovea is not fully formed. It's mainly the immature fovea that hinders a baby's vision in the early months of life.
