The eyes are an amazing and complex organ. Just imagine that we receive about 80% of information through vision. And this is not all of its capabilities.

  • The human eye can distinguish between 30-250 color tones and about 10 million mixed shades.
  • Men suffer from color blindness 10 times more often than women.
  • Women blink 2 times more often than men.
  • The viewing angle of the human eye is 160-170 degrees. For example, a pigeon has a viewing angle of 340 degrees, a cat 185 degrees, a dog and a wolf 30-40 degrees.
  • When a person works at a computer, their eyes refocus 20 thousand times from the computer to the paper or keyboard.
  • It takes 30-50 minutes for the eye to fully adapt to the darkness.
  • Among most living creatures, the eagle has the sharpest eyesight. If we take its visual acuity to be 100%, then a human will have 52%, an octopus will have 32%, and a cat will have 7%.
  • If a person had the visual acuity of an eagle, he would be able to see an ant crawling on the ground from a 10-story building.
  • In 1% people on Earth, the iris color of the left and right eyes is not the same.
  • Humans are the only creatures that have whites of the eyes.
  • The iris of each person is unique.

Take care of your eyes and use their potential to the fullest!
