DescriptionThis color selection wheel allowed patients to choose the color of their contact lenses. Contact lenses were originally made from modified acrylic material. They were "hard" lenses and had to be machined from "buttons" cut from rod stock. These buttons sold for 2-3 cents and the finished lenses sold for up to $400.00. The material used for these contact lenses had been developed by two jewelry salesmen that contracted with Booton Molding to produce ladies watch crystal faces from regular acrylic. The winter after selling the "faces" they fell out of the watches due to shrinkage from the cold. So with no previous knowledge they developed a "no shrink" acrylic material. The material was discovered by the people who were developing contact lenses and their company became the sole supplier to the entire contact lens industry." worldwide. They remained the sole supplier until the advent of the "soft" lens many years later.
