Two "en profil" portraits of Iris illustraing who so many girls and women went for drop temple glasses in the 1970's and 1980's. The portraits also show the major difference in thickness between both lenses. The right lens is minus two but the left lens is -5.50. High index lenses were not invented when these glasses were made. Lens thickness is four millimeters for the right but eight millimeters for the left.
