Teddy dog (definite introduction)
In daily life, it is not difficult to find that dogs will be confused when they are far away. When they find a stranger, they will bark at that target. Especially at dusk, when we basically can’t see anything, they can still detect distant strangers in real time. Do dogs have good eyesight? We don't realize that we have such questions, why can they find others from such a distance?
Many people also often pay attention to the eyesight problem of dogs. Compared with humans, dogs' vision is only about three-quarters of that of humans. Among all animal categories, dogs' eyesight ranks probably at the mediocre level. However, dogs have special detection capabilities for moving objects; they can detect a picture moving at 70 lines per second, while a typical TV picture moves at about 60 lines per second.
Even when the light is dim, a dog’s vision is better than that of a human being. Dogs are talented carnivores that thrive on hunting, so they also have considerable vision in the dark. Dogs' eyes can see short-wavelength colors, so dogs can see more clearly than humans at sunrise or sunset. But in the darkness of total disgrace, even dogs can't see. In addition, the dog's cornea is also larger, allowing more light to enter the eye, making it easier to see in dimly lit areas.
Not only are dogs’ sensory agility about 1,200 times better than humans, but their hearing is also about 16 times better than ours. With these two advantages, they can very well detect strangers who are far away. .
Do dogs have good eyesight? It turns out that dogs' eyesight is not particularly good, but they have more developed senses and auditory nerves, which allow them to detect physical objects well and identify their locations.
