How To Identify Lens Materials

This week we cover how to identify eyeglass lens materials. We examine glass, polycarbonate, Trivex, Tribrid, CR-39 and two high-index materials, 1.67 and 1.74. Opticians sometimes need to identify lens materials when finishing eyeglass lenses. Optician training includes practice on determining material for proper lens edging. Lens finishing lab equipment will require the proper setting to edge a lens. Here we cover the feel, sound, smell and look of various eyeglass lens materials and how-to identify them.
