Rhonda Butler of Fayetteville, N.C., sports Wild Eyes contact lenses - Wildfire, left, and Poolshark. The lenses are painted on the part that covers the iris and not over the pupils, so the wearer doesn't see the designs. The cost of the lenses, made by Wesley Jessen Vision-Care Inc., Des Plaines, Ill., starts at $149. The company, one of several providing the lenses, has marketed them since Jan. 1.
