Animals' eyes are very interesting. Squirrels that are active during the day cannot see at night. Owls often close one eye during the day and open one eye, turning a blind eye to everything in front of them. They can see mice a few feet above the ground when flying in dim light. Bats are blind. They continuously emit high-frequency ultrasonic waves from their mouths and noses during flight. The ultrasonic waves are reflected back after encountering obstacles and prey and are absorbed by their ears. They use "ears" instead of eyes.
Sharks are nearsighted. They use their noses with a keen sense of smell to track and hunt prey. Snakes use their noses to replace their eyes. Their tongues often stick out of their mouths to detect odors in the air and can quickly identify animals that emit such odors. Rattlers use their tongues to replace their eyes. There is an infrared vision device, a thermal locator, under the eyes. It uses infrared rays to see "objects" in the dark and kill the enemy.
Geckos are active at night, and their eyes are very sharp. They can see insects moving in dim light. Cat eyes are like jujube kernels in the morning and evening, narrowed into lines at noon, and like full moons at night. This is due to the light exposure. Rabbits have eyes on both sides of their heads, and can see enemies in front, behind, and in the air. When lizards hunt, one eye can go up or down, left or right, forward or backward, to detect the best way to catch prey, while the other eye keeps its eyes on the target.
There is no dust in the water, so fish have no eyelids, and it is difficult to tell whether they are awake or asleep. The eyelids of dace are transparent, and even if you cover your eyes, you can still see everything in the water. When a seal is at the bottom of the sea, its pupils dilate, and when it returns to land, its pupils contract, and its eyesight is very good. Flatfish lie on their side on the bottom of the sea for a long time, and the lower eye moves upwards and is parallel to the upper one.
Spiders have eight eyes, which can move at the same time to see things clearly and judge the distance. The compound eyes of flies are composed of 4,000 small eyes. The head and neck turn to see clearly in all directions. The eyes of dragonflies are composed of 28,000 small eyes. The small eyes gather into a complete image. The eyes of eagles have a strong sense of three-dimensionality and can see prey on the ground from hundreds of meters high.
