Eye-care company Bausch & Lomb Inc. said it filed a preliminary proxy with U.S. regulators for a special meeting of shareholders to consider its pending merger with affiliates of Warburg Pincus.

Last week, Bausch & Lomb received a takeover offer from rival Advanced Medical Optics Inc. for $75 per share, topping its agreed $65-per-share deal with Warburg Pincus.
