For humans, the world we see is colorful. So as a cat owner, have you ever thought about what the world looks like in the eyes of cats? Maybe you think it is the same as humans, but the editor said that the world in cats’ eyes is green, would you believe it?< /p>

Cat's Eye Structure

The colors that animals can see are determined by the wavelengths of light that the retina can distinguish. Cats' eyes can distinguish blue-green light, which is different from humans. Human eyes can distinguish three kinds of light (that is, the three primary colors of light: green light, orange light and violet light).

The three true colors in art can match any color. The three true colors of light are also general. However, when two three true colors of light are mixed, what appears is not a mixed color, but two different colors of light. Colors (blue + yellow = direct green light, red + yellow = direct orange light. That is to say, the colors that generally seem to have nothing to do with green may reflect green light, because green light may be matched with other colors of light. Yellow and blue appear.

Cats can separate blue-green light, making their world appear rich green-blue and yellow color levels, but the grade is also obvious, which is relatively obvious. The world is only green, which is not unreasonable, but it cannot regard objects that originally lack green elements as green (such as human faces). Human faces are similar to brown and maroon in the eyes of cats.

Another example is a bright red apple that does not reflect green light at all. In a cat's eyes, it may be black. In other words, the cat's world lacks bright colors, but it does not mean that there is only pure green. In an environment with completely cold colors (more red and yellow), the cat's eyes are darker (because the blue and green light that the cat can distinguish is less reflected)

The animal's retina has feelings. There are two types of cells: rod cells for light intensity and pyramidal cells for sensing light color. There are many more rod cells in cat eyes than humans, and the cat's retina is at the front of the eyeball. The light that passes through the retina and enters the eyeball can be regenerated. Directly onto the retina, so even if there is a little tiny starlight, cats can see it. This is why cats can see objects at night, because the lowest light intensity that cats can see is six times that of humans. 1. However, at night, cats are helpless against objects that do not reflect all light (or blue-green light), such as brown mice and red mice (if any). > Talking specifically about dogs, for dogs, dogs are not real.For color blindness, there are far more rod cells than cone cells in dog eyes, so they focus more on distinguishing light intensity. That is to say, the world of dogs is black and white. However, scientists have shown that dogs can also distinguish colors, but Color doesn't mean much to them. If something bright does appear, all the dog will see is pink.
