There are many misconceptions about dogs, such as the belief that they will die if they eat apples or that their mouths are cleaner than human mouths. But to say some things that people, dogs are actually true. One of the common notions about dogs that actually has some truth to the claim that they are colorblind.
Dogs are not in the sense that only displays images in black and white colorblind. However, they have a color field significantly limited in comparisonto see what people can. Most dogs can see what appears in shades of yellow, blue and violet are. You are not able to red, green and orange colors that look to the people, because these colors are somewhere in their range of blue and yellow.
The reason why dogs have difficulty seeing the color is better by comparing their eyes to the human eye to explain. Both man and dog, two types of retinal photoreceptors, rods and cones. However, the human eye has more types of cones, while theDogs eye has more bars and no fovea, people with such detail.
The differences in the eyes of dogs than the people do not always work against them. As a result, dogs have a night vision, which is far above the people and are much better at tracking. However, they are not able to see nearly as much detail and are able to recognize colors and shapes less than human.
If pet owners about how their dogs learn to really seeThings, I often wonder if it's the way it affects the ability to play with their pets. It 'true that if someone throws a ball to his dog orange grass green, yellow is like a ball of yellow grass to find the dog. For this reason you may have problems actually seeing the ball, but will still be able to take it because of their excellent detection of the movement.
There are significant differences between the eyes of dogs and humans, and these make it difficultTo distinguish between colors many dogs that humans can easily see. Even if they can see many different colors, dogs are able to see some shades, and are not limited to seeing only in black and white. The differences in their eyes, the dogs ability to provide superior motion detection, which are different from themselves for their lack of capacity for the real difference between the colors.
