## Abstract

The Food and Drug Administration (FDA or we) is amending the color additive regulations to provide for the safe use of additional copolymers of 1,4-bis[4-(2-methacryloxyethyl)phenylamino]anthraquinone (C.I. Reactive Blue 246) and copolymers of 1,4-bis[(2- hydroxyethyl)amino]-9,10-anthracenedione bis(2-methyl-2-propenoic)ester (C.I. Reactive Blue 247) as color additives in contact lenses. This action is in response to two color additive petitions (CAPs) filed by CooperVision, Inc.
