Dogs can see colors Recently, researchers found that dogs can distinguish different shades of gray, as well as certain colors, especially blue and purple. Dr. Dennis Brooks, associate professor of ophthalmology at the University of Florida College of Veterinary Medicine, said, ‘Dog vision is different from human vision; dogs can’t distinguish various colors as well as people can, but dogs do see certain colors. Dr. Brooks’ research shows that red is dark to dogs, while green is white to dogs, so a green lawn looks like a white patch of grass to dogs. For example, on the left is the grass in the eyes of the dog, and on the right is the grass in the eyes of people. Is it a surprise that the dog is a nearsighted? In fact, compared with us, dogs have relatively poor eyesight. The analogy with data is that if a person’s normal vision is 20/20, most woofers’ vision is only 20/75, followed by 20 and 75 means distance, meaning that what a normal-sighted person can see 75 feet away, a dog has to go 20 feet to see or see clearly. So the world in the eyes of the dog may look like this (of course, the color or whatever is naturally different) The special function of the dog’s eyes although compared with human vision, the dog’s eyesight is really not very good. But at the same time 1. dogs have a special ability to detect moving objects (for example: dogs can detect a picture that moves 70 lines per second, while the average TV picture lines move about 60 per second.) 2. and when the light is dim, because the dog’s cornea is also larger, allowing more light into the eye, so the dog’s vision is also better than human vision 3. the dog’s eyes can see short wavelengths of color, so at sunrise or sunset, the dog can see more clearly than people. These are the special features of the dog’s eyes ah
