To see at night like an owl - how realistic is it?

Many people have long thought about how to see at night, like a cat or any other animal that is capable of it. Especially this question was of interest to the military. After all, if you teach a soldier to see at night, this would give a huge advantage over the enemy. Moreover, the operations carried out by the special forces would be much easier and would bring significant results.

Of course, scientists have already come up with a night vision device that allows you to see at night without loss, but in this case it is very easy to disable a soldier: just turn on the light or turn the flashlight in the face. The shock of the nervous system that arises from this is akin to shock, and a person can even go blind. Therefore, the invention of a new technology, allowing to see at night without using special means, still ranks first among the military inventors.

Thanks to the scientist Kekcheev, who for a long time dealt with this problem, today there is a unique technique that allows to slightly improve the vision in the dark. But still, even thanks to her (despite the mass of announcements promising to teach anyone who wants to see at night without special glasses for a certain amount of money) a vision in total darkness for a person is unattainable.

There is only one known case of history associated with Nikola Tesla and the fact that he came under the influence of a strong magnetic field during one of his experiments. But the case is so legends that, according to one version, Tesla received a unique rumor and ability to see deep at night, and on the other - fell into another dimension. The second version of this legend was even transferred to the screen and shown in the film "Prestige".

It's all about the device of the human eye. He needs a light source to be able to distinguish the surrounding objects. By the way, cats and even owls also need such a source, just so that animals can see at night, the light from it should be much weaker. In the rest they are more focused on sounds.

But back to the development of the scientist. Kekcheev drew attention to the speed of adaptation of the eye to a vision in the dark and sought to raise it. I must say that he succeeded. And the only advice for those who are trying to improve the skill of seeing in the dark is to rub the eyes after getting into a dark place and wearing glasses in the dark with red filters. In the first case, the speed of getting used to the darkness increases, and in the second the glasses are able to "hold" this state and smooth the transition if a bright light source suddenly appears. This, by the way, is very useful for drivers of night flights.

For eyesight in the dark, special cells of the eye - "sticks", called so because of their appearance. If the body lacks vitamin A, then there is a disease called niktalopia, or, as they say, "night blindness". Treatment of it is reduced to the appointment of vitamin preparations. This, incidentally, can serve as an answer to the question of some patients: "What if I do not see well at night?" But uncontrolled consumption of a large amount of vitamin in no case will lead to what a person will see in total darkness. This will only lead to another problem related to hypervitaminosis.
