Visible light is a part of light, and there is a large area outside of visible light that is not visible to the naked eye, at least not to the human eye.

As an ophthalmologist, Xiao Yu has been sitting in the clinic for five or six years, and he has seen all kinds of patients, myopic or not myopic or blind, but this patient who came today really opened his eyes.

This is a teenage boy who was still wearing sunglasses when he was brought over by his parents, and now that he has taken off his sunglasses, Xiao Yu was stunned when he saw it. The boy's eyes were as white as hard-boiled eggs.

Hi there, can you see that?

Xiao Yu waved at the little boy opposite.

You can see, doctor, you don't have to wave.

The little boy saw a reddish silhouette and orange strip waving, and he knew it was a human arm.

Let me ask, have your eyes been like this since birth or have they been acquired?

I was born with good eyes, and I had a problem with my eyes a year ago.

A year did it take you to see the doctor?

Well, I ...... At first, I didn't dare to tell anyone around me, or my parents.

The little boy glanced outside at his mother, who was sitting next to him, and his mother smiled at the doctor, Xiao Yu.

Can you tell us how you're feeling right now?

Uh, how do you say that? It's just that I feel that what I see is no longer what it used to be, and even the color has changed.

Oh? Color? Can you elaborate on that?

For example, if I see you now, it is a red smoke wrapped in a cloud of orange-yellow like a piece of red-hot iron, your forehead is bright yellow, your eyes, nose and mouth are orange-yellow with a little blue, your neck is pale blue, your hands are orange-yellow, and this table is also blue, this cup is orange-yellow, and the liquid inside is pale yellow.

Oh, I see, all your eyes see is the infrared part, and all you see is the infrared light emitted by the object.

Ah, yes, there's a doctor who said the same thing.

It seems that your situation is a bit serious, have you ever thought about removing your eyes and transplanting a good pair of eyes?

I thought about it, but I didn't have the right eyes to replace me, and it dragged on for more than a year, and I really couldn't stand it.

My advice is that you should adapt to your eyes, if you can't change it, you can adapt to it, you can see more, and when you see more, maybe you will get used to it.

Is it? That's all there is to it.

With that, the little boy left with his mother. Just when Xiao Yu was preparing to put away the transcript, he suddenly heard the sound of brakes downstairs, and someone was shouting for help. When Xiao Yu heard this, she quickly stood up and walked to the window to look down, and saw a car parked on the side of the road, and not far in front of her, there was a person lying in the middle of the road, and a woman in a red shirt was squatting on the ground crying bitterly.

Is that? Isn't that the mother of the little boy just now? Could it be that the little boy is lying on the ground?

Xiao Yu was startled, immediately put down the work in his hand, ran downstairs, stood on the side of the road, and saw the little boy covered by clothes holding a sunglasses in his hand.

A few days later, the little boy was cremated into the ground, Xiao Yu didn't need to attend the funeral as an outsider, but after all, the little boy had looked for him before his death. When the godfather finished reading the eulogy, the crowd began to line up to comfort the boy's mother and then put the flowers in their hands in front of the tombstone.

The little boy's mother glanced up at Xiao Yu, a little surprised, but still said thank you.

After everyone left, Xiao Yu stayed, looking at the tombstones that were already full of bouquets, and felt a little uncomfortable. He didn't know why the little boy suddenly couldn't think of committing suicide, and even when he left, his face didn't change, and he couldn't see anything unusual at all.

Thinking about it, Xiao Yu began to blame himself, if he had said more words of encouragement at that time, maybe the little boy would still be alive now. It's all to blame for not thinking well, just thinking about dealing with it casually, and then you can be idle and lazy, and wait until you get off work. I feel that I am not dedicated, it is really in vain that I have worked hard for the past five or six years, and now I can't even keep a little boy.

The more Xiao Yu thought about it, the more angry she became, and the more she thought about it, the more she regretted it, as if she had killed the little boy herself. With a pop, Xiao Yu knelt on the ground, tears of remorse flowed from his eyes, and guilt and self-blame swept through his cranial nerves like a torrent.

Suddenly, he had suicidal thoughts. As soon as this thought came to him, he was a little dazed. He began to think about his life and what meaning his life still had. He looked up at the tombstone in front of him, and suddenly had an impulse to rush up, so he knocked his head directly, and it was a hundred. However, he suddenly remembered his wife, his daughter who was in elementary school, and his elderly mother, and his impulsive brain calmed down again.

Thinking that there are still people who care about and love themselves, and they have people to take care of, they can't just be selfish enough to fulfill themselves and let others suffer.

Wiping her tears, Xiao Yu stood up, smiled, and said: Although you are gone, I am still alive.

After Xiao Yu left, the tears that had previously dripped on the ground slowly rose as if weightless, converging into a mass of water droplets in the air. There are some images replaying in this water droplet, which is the picture of Xiao Yu talking in front of the tombstone. The water droplets slowly floated above the tombstone, then snapped and landed on the tombstone. However, this drop of water disappeared within a second, and I don't know if it was because the temperature of the tombstone was too high and the water droplet evaporated in an instant, or it was absorbed by the tombstone in an instant.

A few words were engraved on the tombstone, and among them was the name of the little boy. The little boy's name is Lishuo, and if you zoom in hundreds of times on the point of the last stroke of the word Shuo, you will find that this point is like a ravine, and there is a river in the ravine, which stops abruptly at the end of the river. It was as if a transparent wall was blocking it, and it was impossible to advance half a millimeter.

A few days later, the boy's mother came again, she placed a plate with fresh fruit in front of the tombstone, and then sat on the ground and began to talk to the tombstone. As she spoke, she laughed, and after a while, she began to cry again, sometimes lying directly on the tombstone in a daze, thinking about nothing, doing nothing.

When she was gone, the tears that had fallen on the ground floated up again, and gathered into a large drop, a milliliter long, enough to fill the last stroke of the shimmering word.

When the tear disappeared on the tombstone, the dot of the last stroke of the shimmering word was also filled with a rushing river. When the river calms down, it begins to glow, from red at first, then to orange, then to yellow, and then to the colors of the rainbow.

Eventually, the colors converged into a bright white that rushed into the sky, shining a large shimmer beneath the clouds in the sky. The bright shimmer lasted for nearly ten seconds before dissipating.

In the years that followed, the word appeared only twice, and only three times at the beginning, but the more it did, the more exciting it became. When he appeared for the second time, Xiao Yu was next to him, and the little boy's mother was also there at that time.

The first word to appear in the sky dates back to more than 30 years ago, when it was also a child, said to be a little girl of one year, who also had white eyes and could only see red, yellow, blue and green. The little girl died at the age of 11 because of congenital heart disease. At that time, the little girl's name was also illuminated in the sky as it is now

The cause of this unsolved mystery has not been explained to this day.

Finish.
