(57) [Summary] [Purpose] The process is simple, the optical function of the UV color changing lens is not deteriorated, and the density is high and sensitive coloring is possible, and the color can be obtained regardless of the thickness and shape of the UV color changing lens. (EN) An ultraviolet discoloration transfer sheet, an ultraviolet discoloration lens, and a method of manufacturing the same which can set the density. An ultraviolet discoloration transfer sheet 1 in which a transfer layer 4 having at least an ultraviolet discoloration layer as one constituent layer is provided on a base sheet 2 is arranged on a female mold 5 having a lens-shaped inner wall, After aligning the base sheet 2 side of the ultraviolet color change transfer sheet 1 with the shape of the female mold 5, the lens material 7 is injected onto the ultraviolet color change transfer sheet 1 to rotate the female mold 5 while polymerizing the lens material 7. The lens material 7 is uniformly thinly stretched and molded along the shape of the female die 5, and the molded product 19 is taken out from the female die 5, A method for manufacturing an ultraviolet color-changing lens 9, which comprises peeling off the base sheet 2 of the ultraviolet color-changing transfer sheet 1. |
