Technical Examples

A method of manufacturing a contact lens having a mark is provided, wherein the contact lens is provided with a mark at the same time as the polymerization of the contact lens in the mold. The coloring composition, for the mark includes a medium which includes at least one monomer component of the monomer mixture used to form the polymer of the contact lens; and a predetermined dyestuff. A concave molding surface is roughened by forming a multiplicity of minute recesses by sputtering to define a marker portion, and the coloring composition is attached to the roughened concave molding surface. The coloring composition is then prepolymerized in the marker position before the monomer mixture of the contact lens material is introduced into and polymerized in the mold.
