We perceive the world in different ways<\/p>\n
Human vision is difficult to call perfect in terms of acuity, visible color spectrum or viewing angle, but people see well against the background of most animals. “Around the World” “looked” at the same image through the eyes of a man, a dog, a fish, a turtle, a fly, a mouse and a parrot.<\/p>\n
Dog<\/p>\n
He has vision that is insensitive to red and orange colors, but he distinguishes shades of gray much better than a person. He sees well at night. It has weak farsightedness (up to + 0.5 diopters), perfectly recognizes moving objects from a distance of 700-900 meters. But it does not distinguish well anything closer than 35-50 centimeters.<\/p>\n
Parrot<\/p>\n
It is capable of perceiving the entire color spectrum and ultraviolet visible to humans. Tetrachromatic: the main colors are red, green, blue, ultraviolet, and the last one is the most important of them. Visual acuity is several times higher than that of a human. Clearly sees over long distances, has the ability to adjust vision depending on the distance to objects.<\/p>\n
<\/p>\n
Mouse<\/p>\n
It has dichromatic color vision. Distinguishes between green and partially ultraviolet. It does not distinguish shades well, but brightness is good. Visual acuity is 30 times lower than human, but it sees much better in the dark.<\/p>\n
Fly<\/p>\n
The eyes are faceted. The vision is mosaic (pixel). Distinguishes between the entire human-visible spectrum and ultraviolet. The main colors are ultraviolet, blue, green and red. It is extremely sensitive to changes in brightness. Short-sighted. Visual acuity is low: he sees about 100 times worse than a person.<\/p>\n
Fish<\/p>\n
It has a developed color perception, distinguishes the entire spectrum visible to humans plus ultraviolet (some fish species can also see in the infrared range). At depth, it is less sensitive to shades of red, sees yellow, green and blue better. Visual acuity is several dozen times lower than in humans. It cannot adjust the vision depending on the distance. Short-sighted, sees well no further than 1.5 meters. The range of visibility is 10-12 meters.<\/p>\n
Turtle<\/p>\n
The eyes are equipped with oil color filters. Has color vision. It is most sensitive to the yellow-orange-red part of the spectrum. He does not see blue-purple tones. Short-sighted.<\/p>\n","protected":false},"excerpt":{"rendered":"
