Dear Dr. Viki…


Who has better vision…my dog or I?

Humans see better during the day. Dogs see better at night.


We see in full color with finer detail. Dogs are colorblind, probably in the red-green color range. They do, however, see far better in the dark.

Dogs have larger corneas (the eye’s clear cap), larger pupils, and larger lenses. These structures allow more light into the eye at night. This light is processed on a greater number of “night” cells at the back of the eye.


In low light conditions, dogs have more information for the brain to process. They have better motion and depth perception. All of this comes at a sacrifice to smaller details. Remember, police dogs are used for their keen sense of smell, not vision.


....Regardless, our cute Eyepolis pooches love their vision in their glasses!
