Why can dogs see at night? What does it look like in the eyes of a dog?

Dogs are color blind and see everything in black and white.

I believe everyone has noticed many times that dogs’ eyes glow, which is a bit scary. The structure of dogs’ eyes is still different from that of humans. Human eyes can only see visible light wavelengths. range, and dogs are much more powerful than human eyes.

In the dark night and when the light is dim, dogs’ vision is better than that of humans. Dogs are natural carnivores and survive by hunting, so they also have considerable vision in the dark. Dog’s eyes Can see short wavelength colors. Therefore, at sunrise or sunset, dogs can see more clearly than humans, but in the darkness with no light at all, dogs cannot see. In addition, dogs’ corneas are larger, allowing more light to enter the eyes, so they are more difficult to see. Easy to see in dimly lit places. . .

So dogs have very good vision at night~~
