A dog’s eyes are spherical. They have the same structure as human eyes, including cornea, lens, vitreous body, etc. The colors of the eyes are basically black, brown, blue, etc. The vision of their eyes is not as good as that of humans, but their night vision ability is better than that of humans. Humans are much better, and dogs’ eyes can’t distinguish many colors.

Tip:

Some dog breeds like to have their eyelids turned inward. Parents should pay more attention to their eyelids when raising such dog breeds, and go to the hospital to correct them if necessary.
