How about a Mad Hatter costume for Halloween? Order a pair of ColourVue Crazy Mad Hatter contacts and turn into this freaky character from Alice in Wonderland. They are yearly contacts available only in zero power.
Pretty turquoise contact lenses great not only as a costume element but also for daily use. ColourVue Crazy The Dexus feature a lovely aqua colour as well as some blue shading in the middle and a black outer edge.
