Why are all puppies "myopia"? Come get off work
Dog's crystal
Dog's eyes have twice the thickness of that of humans, and their eyes have only 1/5-1/3 of that of humans, so it is myopia.
The dog's ability to perceive objects depends on the form of the object. For fixed targets, you can see clearly within 50 meters; for moving targets, you can sense a distance of 825 meters. The field of view of dogs is very wide, with the left and right field of view of a single eye at 100-125 degrees (the human being only 90 degrees), the upper field of view is 50-70 degrees, the lower field of view is 30-60 degrees, and the vision of both eyes can reach 250 degrees.
It sees the objects in front of it more clearly. Since the dog's head rotates more flexiblely, they can completely achieve "seeing the six directions of eyes and listening to the eight directions".
Dogs are color blind
Dogs are color blind, but their field of vision is not only black, white and gray, they can also see colors, but the colors they see are not as rich as humans.
Dogs think that the colors of the world are basically yellow, blue and gray. They think green, yellow and orange are yellow and purple and blue are blue. The blue-green is seen as gray.
Dog's night vision ability
Dog's night vision ability is about five times that of humans. Because their pupils are larger, they can collect more light; there are more photoreceptor cells in the center of the retina of the dog; the lens of the dog is closer to the retina, making the imaging brighter.
In the eyeballs of dogs, there is a reflective tissue called tapetum, which is a mirror-like structure that can reflect light and improve the dog's vision in low light. This is also the reason why dogs have "titanium alloy dog eyes" at night.
Owners should pay attention to protecting their dog's eyes in their daily lives.
If there is a foreign object in the dog's eyes, please ask the doctor for help in time. Do not blindly wipe it with your hands or cotton swabs to avoid damaging the dog's eyes.
It is found that dogs often use their paws to scratch their eyes, red eyes, tears, cataracts, colored secretions, and protruding third eyelids. They must seek medical treatment in time.
