The eyes of dogs and their vision

Bull Terrier - dog factsHi everyone, it’s me again, Mila. Hope you’re all doin’ good.
Here’s another smart dog fact to make you all geniuses.

Let’s talk about dog’s eyes today:
After their birth the eyes of puppies do not fully open before they are about 12 days old. This is different from humans. Human babies usually open their eyes right at birth.

An get this! Every dog has not one, not two – no – THREE eyelids. The third eye lid is called “nictitating membrane” or “haw”.
It serves the purpose of keeping the eye lubricated and protected. In some breeds it is more visible than in others. You may have already wondered about that opaque membranes in your dog’s eyes.

Scientists for a long time assumed that dogs cannot see any colors. Newer studies however suggest that this assumption is wrong.

Dogs can actually see in color.
Our ability of perceiving objects from farther away and perceiving color can be compared to a nearsighted and color-blind human.
That means we don’t perceive colors in the exact same way the average human does and are not able to see as far as the average human (with normal eyesight).
Although there are no studies proving it explicitly, it is believed that dogs can only see one third as far as the average human (again, with normal eyesight).

However, when it comes to darkness, a dog’s vision is much better than a human’s vision. Thanks to a special membrane, called the tapetum lucidum, dogs are able to see objects and detect motion in the darkness much better than in bright daylight.
So, no need to bring your flashlight for the night walk.

Allright folks! Enough wisecracking for now!
Cya next time with another interesting dog fact.
