Humans and most animals have eyes, which are organs that allow them to see their surroundings. Eyes have sensors that detect light. Insects and crabs have compound eyes. A compound eye is composed of hundreds of tiny individual lenses. Each lens sees an image, and the creature’s brain creates one image by putting all of the individual images together. Many animal eyes have a pupil, a slit in the middle of the eyes. This opening gets larger and smaller to let in different amounts of light. Nocturnal animals like owls have large eyes with pupils that can open very wide. This lets in as much light as possible. Human pupils let in less light than owls, for example. Plant-eating animals with eyes on the sides of their head have good side vision. It allows them to keep an eye out for predators while eating. Cats, nocturnal animals, and some deep-sea fish have a shiny layer at the back of their eyes. This layer acts as a mirror and collects whatever light is available. When you see a cat’s eyes shining in the night, it is simply light reflecting off this layer. Some predators and tree-dwelling animals have vision that allows them to focus on objects or prey in the distance. Hawks and falcons have excellent distance vision. Humans have more limited distance vision. Monkeys, apes, and humans have other vision advantages. Each eye views things from a slightly different angle. The brain joins the two views to form a 3-D image. Scientifically Speaking Download 10.24 Kb. Do'stlaringiz bilan baham: |
