Hi guys, Mila here.
Today I have more interesting dog facts about dog’s eyes.
Now we’re getting a little scientific:
Dogs on average have a total visual field of 250 degrees. The degree of binocular overlap is approximately 85 degrees for a short nosed dog versus 75 degrees for long nosed dog. In comparison humans have a binocular vision of about 120 degrees.
Still, dogs enjoy a visual advantage: Human eyes are located directly on the front of the face, while dog’s eyes usually sit a little shifted to a paltry lateral position.
Because of this, a human’s total visual field is only 190 degrees. Remember, we dogs enjoy enjoy around 60 degrees more of peripheral vision, a total visual field of 250 degrees.
However, these are only average numbers, because the visual field of dogs actually depends on the shape of its head and therefore varies among breeds.
