While human 20/20 vision is about two-and-a-half times better than our pets’ eyesight, dogs have a few other tricks that more than make up for the missing cones, especially when night falls, Proietto notes.
“They have much better night vision than we do and are excellent at picking up motion,” Proietto explains. “They don't need the same visual acuity to read or drive a car that we do, so they are wired differently with different receptors in the eye to be able to pick up even the most subtle of motion around them.”
It may make some pet parents sad to think that their dog is missing out on all the colors of the rainbow, but seeing through a faded “gingham” Instagram filter has some serious perks for both pet owners and their pups.
“Their other senses take over, and what they lack in color vision and detail they more than make up for with the aid of their other senses,” Proietto says. “Think of the dogs whose noses have saved so many people just by sniffing them out.”
