A cased optician’s trial lens set with spherical, cylindrical, and prism lenses housed in an oak case with padded inside lid and dating from the early 20th century. The case is in very good original condition and includes 76 lenses in total, each marked by type and lens strength both on the handle to the lens and on the adjacent ivorine labels.
 
The case measures 26 x 25 x 6cm.
 
A really interesting and quirky collectable piece of medical history.
