Method and composition for tinting a spectacle lens substrate

A spectacle lens substrate comprising:

• a polymeric lens material, wherein the spectacle lens substrate exhibits a pattern of a composition containing the polymeric carrier material applied on a surface of the spectacle lens substrate, the polymeric carrier material including at least one material selected from the group consisting of oxidized polyethylene waxes, non-oxidized polyethylene waxes, oxidized polypropylene waxes, and non-oxidized polypropylene waxes, wherein the composition includes a dye substance contained in the polymeric carrier material and/or the polymeric lens material includes the dye substance, and wherein the composition allows for transferring the dye substance from the polymeric carrier material into the polymeric lens material and/or the dye substance from the polymeric lens material into the polymeric carrier material by diffusion upon heating the spectacle lens substrate, wherein a congealing point Tc(carrier) of the polymeric carrier material is above a glass transition temperature Tg(lens) of the polymeric lens material.
