The Hidden World: What Dogs Can See That Humans Can't
There is a common belief that dogs see the world in black and white, but this is a myth.
Our four-legged friends do have dichromatic vision, but they see the world in shades of blue and yellow.
And nature generously compensated for this limitation.
What Dogs Can See That Humans Can't
The dog's retina contains many rod cells that are sensitive to low light.
This allows dogs to distinguish objects and movement in near-total darkness.
There is also a special reflective layer behind the dog's retina called the tapetum, which acts as a light amplifier.
It also helps dogs see in the dark. By the way, it is because of the tapetum that dogs' eyes glow in the dark when illuminated by a flashlight or headlights.
In addition, scientists suggest that dogs can see ultraviolet light; research is currently being conducted on this topic.
Earlier we talked about why dogs stick out their tongues in hot weather.
