Dogs cannot see upside down but they their visual perspective is different from humans. Also, dogs can see sheds of color that humans cannot.
Can dogs see upside down?
We don’t exactly see eye to eye with our furry friends when it comes to color. Yet, dogs and humans process images the same way.
Like humans, dogs use light to perceive an image. Staring at a vertical object, light from the top part of the object hits the bottom of the dog’s eye. Similarly, light from the bottom part of the same object hits the top part of a dog’s eye.
The retina perceives the object as inverted. So technically, a dog should be able to see upside down. But the brain processes the final image as right side up. This means that dogs see everything as is in real life like their human friends.
A dog’s eye is 10 to 20 times more sensitive to motion than humans. Dogs can spot fast-moving objects, like prey, from a distance. This visual advantage came in handy when hunting in the wild.
If your dog was lying on its back and something whizzed past him, he will surely spot it. One more thing, dogs can see some colors we cannot.
Can dogs see color?
A healthy human eye has three color receptors; red, green, and blue. A color-blind eye will have a red-green color deficiency. A dog’s eye has the same color blindness.
To a dog, the world exists in blue, violet, and yellow. The big advantage is that dogs can see shades of grey that humans cannot see. At night, seeing deeper sheds of grey helps spot moving object. Furthermore, a dog’s eye has more light receptors which adds to their brilliant night vision.
If you have peeked through night vision goggles, then you have an idea of how a dog sees at night.
Dogs cannot see upside down because their brains process images as they are. But dogs can see better shades of grey and their night vision is superior. Our furry friends can see fast-moving objects too.
