Commitments and Contingencies Disclosure [Abstract]
Contingencies	Contingencies Since March 2015, over 50 putative class action complaints were filed by contact lens consumers alleging that contact lens manufacturers, in conjunction with their respective Unilateral Pricing Policy (UPP), conspired to reach agreements between each other and certain distributors and retailers regarding the prices at which certain contact lenses could be sold to consumers. The plaintiffs are seeking damages against CooperVision, Inc., other contact lens manufacturers, distributors and retailers, in various courts around the United States. In June 2015, all of the class action cases were consolidated and transferred to the United States District Court for the Middle District of Florida. CooperVision and the other defendants jointly filed a motion to dismiss the complaints in December 2015. In June 2016, the motion to dismiss with respect to claims brought under the Maryland Consumer Protection Act was granted, but the motion to dismiss with respect to claims brought under Section 1 of the Sherman Act and other state laws was denied. The actions currently are in discovery. In March 2017, the plaintiffs filed a motion for class certification. CooperVision denies the allegations and intends to defend the actions vigorously. At this time, we do not believe a loss or adverse effect on our financial condition is probable nor is any range of potential loss reasonably estimable. The Company is involved in various lawsuits, claims and other legal matters from time to time that arise in the ordinary course of conducting business, including matters involving our products, intellectual property, supplier relationships, distributors, competitor relationships, employees and other matters. The Company does not believe that an estimate of possible loss or a range of loss can be made at this time.
