Qin Jun took out a few hundred yuan from his pocket and handed it to the beggar, who was smiling and pretending to thank him.

Then he took the money and left.

Seeing that Qin Jun gave the money, the students frowned and said nothing.

"Which department is this boy from? Why is he so brainless that he can be cheated?"

They all shook their heads and said they were speechless. They walked over together and talked to Qin Jun.

"Man, which class are you in?"

Qin Jun Leng for a while, said with a smile, "I'm not a student."

No wonder you are not a student of our medical university? I said, "why can't you see that he's pretending to be blind?"

Qin jundao, "I see it. When I take off my sunglasses, he has a pupil reaction, which is obviously blind."

A few students a Leng, "you are not our school students, then you are a doctor?"

"Yes." Qin Jun nodded.

The monitor and several classmates all laughed, patted Qin Jun on the shoulder and said.

"Man, your medical skill is a little bad. We all know that he pretends to be blind and pays back money. What's your situation?"

Qin Jun helplessly shook his head, "although he is not blind now, he will soon be blind, and his eyes have been terminally ill with acute keratitis."

The monitor was stunned for a moment and then laughed.

"Come on, man. Acute keratitis? Isn't that red eye disease? What is the saying that red eye disease is incurable? Forget it, I don't think you understand it, so don't pretend to understand it. If you have money, you don't want to give it to us. OK, let's go. "

Several students turned back to school, ready to go to master Qin's class.

We are still discussing on the way, saying that Qin Jun must be from other departments, otherwise he would be a dirty doctor and would not do anything.

Acute keratitis is commonly known as red eye disease. This disease is the simplest. In fact, it means that people don't pay attention to hygiene and rub their eyes with their hands. There is dust or other dirty things in their eyes.

In addition to their own cold or physical weakness, will have this disease.

Acute keratitis is very easy to treat, if there is no disease in itself, wash hands frequently, pay attention to hygiene, 10 days or so can be self-healing.

If combined with sodium hyaluronate eye drops, plus ofloxacin eye drops and other eye drops, can recover faster.

The fastest three or four days can be effective, even if it is laissez faire, it will not have any effect on the eyes, at most is uncomfortable.

The most ridiculous thing is that Qin Jun said just now that this kind of acute keratitis can lead to his blindness, which clearly means he doesn't understand it at all.

Seeing the discussion of these students, Qin Jun was helpless.

This is the gap between these students and him.

Acute cornea, though not blind, can heal itself.

But there must be a premise, that is, the patient's body should be normal and there should be no other diseases.

There is no disease, and physical health, self-healing is no problem.

But now it's not the same. The beggar just now, Qin Jun, can see at a glance that his lips are white, his nails are flat, and there are some white marks on his ears, which is obviously infectious.

Once such a person is infected with keratitis, it is difficult to recover. In addition, if he is blind every day, he should wear some contact lenses or other things on his eyes, which will cause a little damage to his eyes.

In the daytime, the environment is messy and poor. In order to beg, it's natural to make it dirty. Under such unsanitary conditions, the beggar will be blind within two months.

……

After entering the school, Qin Jun found Cai Changfu and several school leaders.

Seeing that he was so young, several leaders were confused. They were all at the level of professor and associate professor. Today, I heard that master Qin was coming to attend the class.
