Cased Measurer or Sizer for contact lenses manufactured by famous German makers Carl Zeiss Jena complete with a pair of lenses. The lenses are early Dr Norman Bier contact lenses from the 1940s which also come with original case. The measurer consists of a removable granite tray, all very well made. Both of the rubber applicators have gone hard as expected and the one in the measuring tray is wedged tightly. I have not tried to remove it for fear of damage. Wooden case measures 26.5 x 11 x 3cms. An excellent rare piece of medical history.
