Litigation challenging the pricing policies of the nation’s biggest contact lens makers has reached the Southern District of Florida.

On March 6, Robins Kaplan, a Minneapolis-based civil trial firm with a Naples office, filed an antitrust lawsuit in Miami federal district court against the four manufacturers and the largest nationwide distributor of contact lenses—CooperVision, Alcon Laboratories, Bausch + Lomb, Johnson & Johnson and wholesaler ABB Optical Group. The lawsuit seeks certification of a nationwide class action and a jury trial.
