Abstract

The coloring of polymeric eyeglass lenses is used for sun glasses production. Time influence of surface staining of polymer material CR-39 and the dye concentration on its spectral characteristics and the refractive index changing is researched. It is shown that with time increasing of surface staining the refractive index and
transmittance decrease.

Keywords: surface coloring, polymeric material CR-39, reflective index, transmittance
