Just A Quickie


Recommended Posts


The eyes of a dog are similar to human eyes with the retinal covering over the eyeballs containing two types of light sensitive cells, cones and rods. The color perception and the details of the vision are controlled by the cones, while the dog eyesight at night is controlled by the rods which is able to detect the motion. Due to the larger concentration of the rods as compared to the cones, dogs are able to detect the motion better. This low concentration of cones also is the factor that has given rise to the myth that dogs are unable to see color.

 

According to veterinarians, dogs are able to see colors the way a colorblind human would see. Color blind people have a trichromatic or a dichromatic vision. Similarly dogs too are unable to distinguish certain colors like the reds and the greens. The set of the dog's eyes may vary with the breed but the general angle is somewhere around twenty degrees. This helps in increasing the peripheral vision and the field of view of the dog.

 

While the peripheral sight helps the dog have a wider field of vision, it also results in a compromised binocular vision. Along with that, they have less visual acuity and unlike humans with a perfect 20/20 vision, they are unable to see things from far off. Some dog breeds like Labradors have a better eyesight. In addition to peripheral vision, motion sensitivity is an important part of dog eyesight.
