NORRISTOWN, Pa. — Bill Cosby’s eyesight has deteriorated to the point where he cannot identify his accusers in photographs or otherwise help with his defense, his lawyers said Wednesday as they waged a multipronged effort to get the sexual assault case against the 79-year-old comedian thrown out.

His attorneys also portrayed Cosby as a political pawn who is being prosecuted only because a suburban Philadelphia district attorney used the public furor over the comic to get elected last year.

And they renewed their argument that Cosby’s lurid 2005 deposition from a related lawsuit should not be admitted at his trial, saying he answered questions under oath only after being assured he would not be charged with a crime.

Cosby leaned back in his chair as his lawyers made their case at the two-day pretrial hearing, which ended with no rulings from the judge and no indication of when he might issue one. Another set of hearings is scheduled for next month.

The “Cosby Show” star once known as America’s Dad is scheduled to go on trial by June on charges he drugged and molested Andrea Constand, a former Temple University employee, at his home in 2004. He could get 10 years in prison.

Cosby has said the encounter was consensual. He is free on $1 million bail.

Dozens of additional accusers have come forward, including 13 women whom prosecutors want to call as witnesses at the trial to show that they were drugged and violated in similar fashion. Cosby’s lawyers are fighting that strategy.

Defense attorney Angela Agrusa argued that prosecutors unfairly prejudiced Cosby by waiting a decade to charge him. Cosby has memory problems and is also legally blind, according to the defense, which presented a medical report that said he is blind in his right eye and has glaucoma in both eyes.

However, prosecutors said Cosby himself caused the delay by fighting efforts by The Associated Press – in 2006 and again in 2014 – to unseal his testimony in Constand’s 2005 lawsuit.
