The conservative commentator told an audience attending his "American Revival" tour over the weekend in Salt Lake City that a doctor told him he has the degenerative disease macular dystrophy.
Beck says he went to a doctor for testing because he had trouble focusing with his eyes. "He said, `You have macular dystrophy. ... You could go blind in the next year. Or, you might not."
Beck said he replied: "Did you just charge me a thousand dollars for knowing what I knew my whole life?"
The disease generally makes itself known by a decrease in vision in 20- to 40-year-olds. Beck is 46. The WebMD website says eyesight deteriorates as the disease progresses.
