Do humans have better eyesight than animals?
Some animals, even ones with eyes are blind or have very poor eye sight (bats aren’t blind, but “see” in the dark by echolocation). Other animals, most famously hawks, have exceptional meyesigh, and can see their prey from way up in the sky. Before going any further, let me explain about how light is perceived. There are two light-sensing cells in the retina of your eye – rods and cones. Rods detect black and white and are very senitive to light. They are good for detecting motion and night vision. Cats have lots of rods, so they can hunt easily at night. Cones distinguish color. Humans have excellent color vision, as many other animals do, but some, such as dogs, are color blind to certain colors, which appear washed-out. Humans have many rods as well, but are not nearly as good at night vison or seeing motion from far away as a cat or a hawk. I don’t know of any animals with x-ray vision, but some insects, such as bees, and some snakes can see infrared light (heat vision). Electromag
