What is the experience of having a pair of super powers?

  The old saying goes, “The eyes are the windows of the soul.” Familiar people can recognize each other through their eyes. It is obvious that the eyes are very important and unique in the five senses. Anime often likes to show super power through the eyes. The eyes of “Journey to the West” can be seen through the monsters at a glance; the white eyes of “Naruto” have the ability to see through and look at the distance; the eyes of the ancient language of “Knife” It’s even more arrogant. Everything in the world can be completely understood and used as long as you have seen it with your own eyes.

  There are too many super power eyes in art works. What if we can get one of them? Let’s start by seeing the light that others can’t see.
We don’t see all

  The light we see is actually an electromagnetic wave radiated by an object. The wavelength of the electromagnetic wave ranges from 0.001 nm to 3,000 m, and the wavelength of the electromagnetic wave that can be seen by the human eye is only between 380 nm and 780 nm. For example, if we amplify the longest wavelength of electromagnetic waves into the distance of the moon from the Earth, the wavelength of human visible light is only between 5 and 10 centimeters, just a tiny segment. This electromagnetic wave transforms the signal through the human eye, and we see the colorful world, but the light seen by other animals is different from ours, and their world is different from what we see.
  Like humans, bees are sensitive to light of three colors, but their three primary colors are not red, green, and blue, but yellow, blue, and ultraviolet, which can see electromagnetic waves with shorter wavelengths than visible light. The ability of bees to see ultraviolet light allows them to recognize patterns on petals and find nectar. There are thousands of lenses in the compound eye of the bee, each of which produces a “pixel”, plus their ability to see ultraviolet light, the petals are sparkling in their eyes. Even so, the pixels produced by the bees’ eyes are not enough to make them look at the objects, and the world in their eyes is very blurred.
  The rattlesnake has a habit of nocturnal nights, and its eyes are also adapted to this. It can’t see the color during the day, but at night it can see the fast-moving mice because they can distinguish the infrared light, that is, the wavelength can be seen. Electromagnetic waves longer than visible light. The rattlesnake has a special perceptual tool called the “women” – a pair of small holes on each side of the snout between the eye and the nostrils. The socket can sense the temperature of the object and the infrared light radiated, and then convert the induced infrared light into a nerve signal. Because the wavelength of the infrared light radiated from different parts of the mouse is different, the rattlesnake can see one in the dark. Only colorful mice.
  The squid has only two types of photoreceptors, one that makes the world in its eyes appear gray, and the other that senses polarized light. Usually, the natural light we receive will be shot from all directions, and the polarized light refers to the light determined by the direction of beam propagation. Only humans can wear polarized glasses to filter out the light from other directions to see. When watching 3D movies. The special glasses worn are polarized light, and the polarized light directions received by the left and right eyes are exactly vertical, so that the left and right eyes respectively receive different images, which gives a strong stereoscopic effect. Squid can see polarized light without wearing glasses. They produce polarized light patterns on the body surface to communicate with other squid. These patterns are invisible to other creatures and are their unique means of communication.
  Dogs can distinguish between different shades of blue, scorpion and purple. The ability to recognize colors is not as good as humans, but they have special ability to detect moving objects; cats are similar to red and green blinds, and can’t distinguish between red or green things, but Cats can see more clearly than humans at night.
If we can see all

  If you can see the range of electromagnetic waves as an indicator of the strength of eye vision, some animals have better visual ability than humans, while others are weaker than humans. But in fact, animals and humans now have eyes. The best, because this part of the electromagnetic wave can be seen is the most useful for survival, if the organism can see all the electromagnetic waves is not a good thing, it is impossible, because the electromagnetic energy of different wavelengths, the energy carried is not the same. The shorter the wavelength of the electromagnetic wave, the higher the energy, the more harmful it will be to people. Even if it is ultraviolet light, it will cause harm to people for a long time, let alone X-rays and higher-energy gamma rays, so our eyes are affected. No. On the contrary, the longer the wavelength of the electromagnetic wave, the lower the energy, and the irritating cells in the human eye cannot be stimulated, so the human eye cannot see it, and only a special instrument can detect it.
  If we want to see more electromagnetic waves and ensure clarity, we need a pair of very large eyes and a big head, because only large eyes can guarantee enough pixels to process the received electromagnetic waves. The brain can store the converted light signals and analyze them. Perhaps this is why people imagine that humans have big eyes in the future.
  If we can see the visible light that is visible now, the infrared light emitted by the object, the ultraviolet light emitted by the sun, and the WiFi signal that spreads all over the world, then the universe will no longer be dark, it is full of high-energy rays. All objects with temperature emit infrared light. The higher the temperature, the brighter the infrared light, we can see the temperature of the object at a glance. Maybe we will communicate like this: “Be careful, you see it ‘color’ so deep!” “I’m cold today, I’m so cold.” And when I can see ultraviolet light, we no longer need to check the money. Machine counterfeit, you can also walk around where it will radiate ultraviolet rays.

  Unfortunately, all this is just a good imagination. The truth is that if we can see all these electromagnetic waves, we will only be “brightened”! Even if we only see infrared light and ultraviolet light, it is equivalent to seeing electromagnetic waves between 1 mm and 120 m. That is, we originally only accepted light between 5 and 10 centimeters, and now it has expanded several thousand times. When the sun rises, all objects will reflect light, and your world will become a bright, shimmering spot. When the air has color, its color will also be mixed with other objects. How do you distinguish between the road where only the air can pass, and the other is the wall that cannot pass?
  There may be some benefits in the evening. Objects with temperature will emit infrared light, and at night it will be as bright as daylight, so we can see the object like a rattlesnake. But I don’t know if you would like to see the colorful people who are composed of red, green and yellow, or do you want to be a multicolored, inconspicuous mosaic-like person in the eyes of others?
  In fact, the eyes we have now are the most suitable. After all, this is the result of our adaptation to nature for thousands of years, but humans always hope that they can get more. Scientists are studying how to make people see the infrared light.

  If we have a pair of eyes that can see the infrared light, how good! Now scientists have begun to work in this direction.
  We already know that in the dark, the visual matter is the contribution of the rod cells. The photoreceptor in the rod cells is vitamin A, so American scientists think of a way to do the opposite. They don’t eat vitamin A. Only eat vitamin A2, because they believe that vitamin A2 can increase the wavelength that visible cells can absorb, and extend the range of visible light to the infrared part. The participants in the experiment mixed a certain dose of vitamin A2 with the nutrient powder and drank the powdered water all day to ensure that they did not consume any vitamin A. This persisted for 25 days and the results showed their The eye really responds to infrared light with a wavelength of 950 nanometers.
  Although this experiment did achieve results, it also has great risks because the lack of vitamin A in the human body can cause night blindness, and this effect may be irreversible. Chinese scientists have found a safer method.
  For human eyes, the energy of infrared light is weak, and it is impossible to stimulate the sensor in the eye to generate signals. In order to make the human eye feel the infrared light, scientists need to find a material to improve the energy of infrared light, rare earth nanoparticles. It is the most suitable material they have found.
  The scientists used two kinds of rare earth elements, lanthanum and cerium, to prepare nanoparticles. In this combination, strontium atoms are responsible for absorbing infrared light. The energy of infrared light causes electrons and photons inside the cesium atom to collide continuously, producing a source. A wave of high and low undulating energy waves that are transmitted to nearby helium atoms. The helium atoms have powerful traction, which can collect more energy and then release them in the form of high-energy green visible photons. The photons captured by the receptors in the eye can make people see green light.
  To confirm this theory, they performed experiments on mice that resemble human eyes. They can only sense light between 400 nm and 700 nm and do not see infrared light. However, when scientists injected nanoparticles into the eye of mice and then modified the eyes with infrared light, they found that the mice had a contraction response to infrared light! The scientists also used infrared light to direct the mice to find floating plates in the pool. The mice with modified eyes responded to infrared light and could find hidden floating plates. The mice that did not receive nanoparticle injection were only in the pool. There is no purpose in the middle of the chaos.
  This experiment has been successful in mice, but more research is needed in humans because its safety and efficiency still take time to test, but glasses made of rare earth nanomaterials for visible infrared light Maybe it would be a good choice.
  Infrared light can penetrate the human body to where visible light cannot penetrate and produce therapeutic effects. It can also be used to study how light interacts with organs in our body. If a doctor has a pair of eyes that can see infrared light, the patient It is a good news.
