Jokes about eyesight

An old captain has poor eyesight, but he can pass his eyesight check every year. It turned out that he had memorized the vision checklist. But this year, the doctor changed a new vision checklist. As a result, the old captain's eyesight was almost blind. The doctor couldn't help but ask him curiously how he flew over these years.

Doctor: "How did you get the plane to take off smoothly?"

Old Captain: "It's very simple. Just listen to the instructions from the tower. What's more, I have been flying for so many years, and I know exactly what the runway looks like."

Doctor: "Oh, I understand, but what about after takeoff?"

Old Captain: "It's easier after take-off. Just change to automatic frame driving."

Doctor: "Well, what about landing?" It's not easy! "

Old captain: "Of course, I also listen to the instructions of the tower, but I will listen carefully when I am about to touch the ground." . . When I heard the co-pilot start shouting "Oh, my God!" I know it's time to pull up the nose, and then we will land smoothly and beautifully. "
