Eyeglasses made at seven top optical chain stores failed to meet basic standards set by the industry for precision and workmanship in an unscientific survey, CBS News reported Wednesday.
A New York optometrist who helped write the industry's standards for glasses, after examining glasses made at the seven stores, said in the report that glasses made at all seven outlets flunked.
"Every one of them fails the industry requirements," said optometrist Robert Rosenberg of the State University of New York.
The program sent an undercover shopper to seven eyeglass outlets in New York with a routine prescription for bifocals.
Problems with the finished eyeglasses -- which took between an hour and a week-and-a-half to make -- ranged from an incorrect astigmatism correction to lenses being so loose that a piece of paper could be slipped between them and the frame, the report said.
The seven franchises involved in the survey were Pearle Vision Express, Lenscrafters, Cohen's Fashion Optical, Sterling Optical Corp (EYE.N), Sears (S.N), BJ's Wholesale Club and Costco Wholesale.
