From all-round academic master to chief scientist

Light, as light as paper.

Light, scattered everywhere.

From a physical point of view, visible light is only a type of electromagnetic wave, or in other words, it is just a visible electromagnetic wave, and different organisms can see different visible light.

The human spectrum covers between 312 nanometers and 745 nanometers, and snakes even have infrared vision, which means the wavelength is larger than red. It is this ability that gives snakes similar thermal imaging capabilities. .

Therefore, from this perspective, human visible light is only special for humans, but for other creatures, it is another kind of special.

Of course, from a scientific perspective, this is true.

From a theological perspective, light is a creation of God that enables people to walk under the light.

But no matter what the explanation is, light is obviously an essential thing in human life.

But obviously, for the blind, this kind of thing is indispensable and has become a must-have.

For those who are congenitally blind, this is even more desperate, because they don’t even know what the world looks like, they don’t know light, dark, lake blue, or navy blue.

After all, when explaining to them, it is impossible to say to them: "The RGB values ​​​​are 0, 235, and 192 are lake blue, and the RGB values ​​​​are 0, 0, and 128 are navy blue."

So for Tingting, she never knew what "brightness" meant.

However, at this moment, after Lin Xiao's explanation, she finally understood what "bright" meant.

"This is light, is this brightness?"

Tingting felt extremely surprised in her heart.

Can she really see the light?

In other words, can she really see the world?

But soon she asked: "But why can I only see light now? I still can't see my father."

Lin Xiao smiled slightly, "Don't worry, because some medicine was used on your eyes, so your eyes are now wrapped with gauze. It will take a while for the medicine to be absorbed before it can be uncovered, so you are here for the time being. Just wait a little longer.”

"good!"

Tingting happily agreed.

Then, she waited peacefully.

Anyway, I have been waiting for so long, and I don’t lack these few hours.

In this way, time passed quickly, and it was a few hours again.

And it was already dark.

Of course, although it is dark, the lights in the bustling city are still bright.

The lights of thousands of houses outside the window contrasted with the bright light inside the window.

At this time, the nurse began to remove the gauze on the faces of the three blind people.

By this time, judging from the reactions of the three blind men, it was basically certain that their vision had recovered.

So they should now be able to call them "formerly blind".

In the past, it was impossible to combine these two words in this way, because the blind person would be irreversible after becoming blind.

"Come on, Tingting, sit up, sister, let you see the outside world now."

The nurse said to the little sister gently.

Tingting also sat up obediently, and then waited for the nurse to remove the thing on her face that finally blocked her from contacting the world.

Slowly, the gauze was lifted.

The white upper eyelids were slowly raised, and a pupil that looked like a pair of colored contact lenses appeared inside.

For the sake of appearance, the pupils are made like this, giving it the feeling of big two-dimensional eyes.

However, everyone around them did not care about how beautiful the contact lenses were at this time, but instead cared about whether Tingting could regain her vision.

However, what they were all confused about was that when Tingting opened her eyes, she seemed to be stunned.

She opened her eyes and stared blankly ahead.

Everyone is thinking, what happened to Tingting?

In fact, Tingting was just shocked by everything in front of her.

As the gauze was lifted, she opened her eyes, and the colorful world appeared clearly in her field of vision.

She watched in shock, and her brain seemed to be shocked. She didn't expect that more than ten years had passed, and the visual nerve that had never played a role suddenly sent so much information to her, so she began to mobilize it. The almost rusty light information processing area begins to process this information, and then allows its owner to see these things.

So, Tingting saw the ward of unknown color, the quilt of the same color as the ward, and so many... things that were probably human beings standing around.

"Tingting, how are you...?"

There was a sound coming from the side. Tingting turned around and looked at the place where the sound came from. She saw a person - she was basically sure that this was a person.

And that voice was also a voice that was extremely familiar to Tingting.

Then, she suddenly pounced.

"dad!"

she shouted.

"Dad, I can see you!"

When he felt his daughter hugging his arm, the man's expression suddenly changed.

From excitement to joy, from relief to lamentation, but in the end it all turned into tenderness for her daughter.

"Dad knows, dad is always watching you."

Looking at this scene, everyone around them couldn't help but be moved by it. Even the nurse who had removed the gauze from Tingting before, her eyes were even redder and moister now.

Such a scene is no less than a father and daughter meeting each other after fourteen years of separation.

At this time, another excited voice came from the other side of the ward.

"I can see again! I can see again!"

Everyone looked again and saw that the person who shouted these words was the 35-year-old blind man. He used to be a man with perfect vision, but later he gradually lost his vision due to heavy blows to his eyes.

If Tingting is the excitement of gaining light, then he is the joy of regaining light.

The former comes from the sense of gap that everyone else has but only you don’t have, and the latter comes from the regret after losing something you once had.

At this moment, they were all happy with the brightness in front of them.

Finally, the sixty-year-old man also successfully restored his eyesight. The old man had been blind for nearly thirty years. Needless to say, the joy of regaining his eyesight at this time also means that he can regain his sight when he is old. Take another look at the world, or look at his children again.

At this time, the old man had met his child again. When he lost his sight, his child had not grown up, and was not even ten years old. But now that he has regained his sight, he looks like he had just A child who looks very much like himself when he becomes blind.

The old man smiled, reached out and gently touched the child's face, and said, "You have grown up, and I finally see you grow up with my own eyes."

After hearing his father's words, his son, although he was now in his thirties, burst into tears and hugged his father.

"dad!"

…

There were so many touching scenes that everyone present could not help but be moved by them.

Seeing the world is a normal thing, but for the blind, it becomes abnormal.

But at this moment, they can all see, or see the world and their loved ones again.

People were moved.

While feeling emotional, no one has forgotten what it was that made this scene become a reality.

Electronic prosthetic eyes!

Everyone couldn't help but turn their attention to the genius scientist.

At this time, Lin Xiao was also looking at everything in front of him with a smile on his face.

He seems to be happiest when he can see the technology he created realize such a scene.

This is exactly what he paid for, and what he wanted to get in the end!

Of course, this also demonstrates the power of technology.

Technology is constantly developing, and more scenes like this will inevitably appear in the future.

Just like in the past, when the technology of video conversations through cameras first appeared, it made it possible for many people who were thousands of miles away to miss their loved ones through photos, to be able to chat face-to-face with their loved ones while sitting at home.

Lin Xiao couldn't help but feel sorry for it.

This is where technology should really play its role and show its charm, rather than those killing technologies that appear for the purpose of war and killing.

But what is helpless is that these weapons have to be developed.

Thinking of this, he sighed softly.

Next to him, Chen Xuan, who had never left, couldn't help but asked: "Academician Lin, why are you sighing? What a beautiful scene, sighing is not good."

Lin Xiao smiled and waved his hand: "I know, I just feel a little sad in my heart."

Chen Xuan nodded and did not ask Lin Xiao what he was feeling. People always have sentimental moments, and he has also experienced sadness in spring and autumn.

Of course, looking at all this at this time, he could only feel happy.

"That's great. Now, I may know the answer to the question just now."

Lin Xiao was startled, and then remembered the problem.

He smiled and asked, "What do you think the answer is?"

Chen Xuan laughed and said: "The answer is - why do I think so much? I can see what the world looks like, but I am old, so I might as well spend more time with my family, hey, so I I'm leaving."

Then he waved his hand, turned around and walked towards the door. At the same time, he shook his head and said: "It's rare that I have nothing to do today and no research. I actually came to the hospital to hang out. What a sin."

Lin Xiao was stunned for a moment, looking at Chen Xuan's leaving figure, and then couldn't help but shake his head with a smile.

Birth, old age, illness and death are inevitable topics for human beings!

So what will happen when he faces these four?

He didn't know.

No longer caring, he turned around and walked to the window, looking at the thousands of lights outside the window. Maybe none of them were lit for him, but I believe that everyone inside would be grateful for what he had done, right?
