The optic nerve delivers these signals from retina to brain. Surprisingly, dogs have a wider view than humans but may have poorer vision.

   Aug 2, 2004 · Compared to the human eye, the dog has a larger lens and a correspondingly larger corneal surface, enhancing its ability to capture light and thus see in reduced lighting conditions. In addition, behind the dog’s retina is a reflective surface, the tapetum, which further enhances low-light vision.

   How does a dog's eye work?

   • The cornea is transparent, while the sclera is a tough coating to protect. The iris adjusts its size according to the light. The ciliary body shapes the lens to focus, and the choroid provides blood flow. Canines have an extra feature: the Tapetum Lucidum. This layer makes their eyes glow in low-light conditions and gives them better night vision.

   Why do dogs have 3 eyelids?

   • This transforms light signals into the optic nerve and off into the brain. This is the white part of the eye that surrounds the iris. Dogs have three eyelids: an upper, a lower and then a third eyelid. They mainly serve to protect the eye, the third eyelid sweeping back and forth to spread tear film and keep the eye moisturised.
