Can dogs see without turning on the lights at night? Pet owners, come and learn more

Dogs can see without turning on the lights at night, and they can maintain good vision at night. Moreover, dogs’ sensitive sense of smell and hearing allow dogs to maintain amazing perceptions at night. The night vision ability of dogs is five times that of humans. The structure of dogs' eyes is the same as that of humans, including cornea, sclera, iris, ciliary body, retina, lens and vitreous body.

However, dogs’ pupils are larger than humans and can collect more light. Moreover, there are many photoreceptor cells in the center of the dog’s retina, which can adjust in low-light conditions. Among all animal species, the dog's vision is about medium. The dog's single eye can only see 25 degrees, so it cannot see the nearest distance from the front. The lens of a dog's eyeball is relatively large and deformed like a horse's eyeball, so it is impossible to adjust the sense of distance. Twenty or thirty meters is approximately the limit.
