Polish man was blind for more than 20 years, but he saw the light again after a car accident. What's going on here?

Polish man was blind for more than 20 years, but he saw the light again after a car accident. What's going on here? There is no clear answer to this matter at present. There are many amazing places in the whole incident. Let me introduce them to you:

First, the Polish man was blind for 20 years and saw the light again after the car accident:

Janus Goray is a Polish man who has been blind for 20 years. He suffered from retinal problems in his eyes 20 years ago because of allergies, and he has lost his sight since then. Janus Goray tried many methods, but none of them worked. Many doctors think it is impossible for him to see again. But the world is always full of miracles. Just recently, he had a traffic accident, which resulted in Janus Goray's hip fracture. After that, he was taken to the hospital. After treatment, he was finally out of danger. After that, Janus Goray continued to be hospitalized for two weeks. Just when he was discharged from the hospital, Janus Goray found that his eyes had regained sight. What is particularly surprising is that his eyesight is very good. Second, the hospital staff can't explain it:

Sputnik also made relevant reports. According to the hospital doctor, nothing special happened during the patient's hospitalization, and everything was quite normal. The medical staff in the hospital also treated him according to normal conditions. So the hospital has no special means, and there is no way to explain how that person recovered his vision. At the same time, the medical records of the hospital also show that he was treated according to the injury at that time. 3. Scientists are conducting analysis and research:

The Janus-Goray incident has attracted the attention of some Polish scientists, who have already started their research. Of course, these studies are only aimed at the drug use in hospitals to see if some drugs can help Janus-Goray recover his eyes. Now scientists are working hard, and the follow-up situation has not yet come out.
