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.

- 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.
