CooperVision issued a second announcement on Wednesday on an August recall of 600,000 Avaira Toric contact lenses.
The lenses have been linked to pain, redness and blurred vision, apparently from a residue caused by a manufacturing problem.
The company first announced the recall on Aug. 19, but it had focused recall efforts on the eye care professionals who sell the lenses.
CooperVision said it "has fully cooperated with the FDA and continues to closely monitor the situation."
More than 8 million lenses are affected by the problems, according to the FDA, though only 600,000 made it onto the U.S. market.
The Associated Press contributed to this report.
