You've probably already read a lot about the eyesight of our four-legged friends. Most often we encounter the fact that dogs see in black and white, blurry, but good in the dark. So let's look at the world through a dog's eyes and find out what the truth is.
CAN DOGS SEE COLORS?
Many people believe that pets see in black and white and their eyesight cannot distinguish any of the colors around them. But scientists have proven that this is not entirely true. The color spectrum that a dog's eye can perceive is actually much more cheerful. So a dog sees colors, but not in the same number of shades or in the same intensity as we humans are able to perceive.
Specifically, it captures two groups of colors. Yellow, orange, red and green belong to one, blue and violet belong to the other. The dog is not able to distinguish individual colors, but it can distinguish the mentioned groups from each other. So if you are thinking about what color to buy for your dog a toy , the best is blue or purple, which it can safely distinguish from, for example, green grass and the toy will therefore not blend in with it.
ALMOST AROUND THE CORNER
Furries can see far fewer colors than we do, but they boast amazing peripheral vision. While humans have a field of vision that extends up to 180 degrees, dogs can see 240 degrees, giving them an almost panoramic view. Because their eyes are further apart than ours, they can see things that we only see when we move our heads.
THEY ARE SHORT-SEEING
The further an object is, the more blurred the dog sees it, which could be compared to myopia. Fortunately, the furry ones have a perfectly developed sense of smell, which compensates for this "deficiency".
CAN THEY SEE IN THE DARK?
You can't say that they can see clearly in the dark. But we know for sure that in order for dogs to survive in the wild and to hunt, they see very well even in dim light.
It turns out there's another fascinating fact about dog vision that explains their behavior. Does your dog like to watch TV with you? This is because it perceives the TV image three to four times faster than the human eye. Therefore, modern high-definition televisions provide pets with a much greater source of entertainment than the old, low-quality ones, where they saw a blurry picture.
