PURPOSE:To enable color density to be set irrespective of a thickness and a shape of an ultraviolet discoloring lens by a method wherein coloring which is deep in density and good in sensitivity can be carried out without lowering optical function of the ultraviolet discoloring lens by a simple process. CONSTITUTION:An ultraviolet discoloring transfer sheet 1 wherein a transfer layer 4 having at least an ultraviolet discoloring layer as one component layer is provided on a substrate sheet 2, is arranged on a female mold 5 having a lens shaped inner wall. After making a substrate sheet 2 side of the ultraviolet discoloring transfer sheet 1 be along a shape of the female mold 5, a lens material 7 is poured onto the ultraviolet discoloring transfer sheet 1, and the lens material 7 is molded by spreading uniformly thinly along the shape of the female mold 5 by rotating the female mold 5 while the lens material 7 is being superimposed thereon. Then, a molded product 19 is taken out from the female mold 5, and the substrate sheet 2 of the ultraviolet discoloring transfer sheet 1 is separated. |
