Historical Significance: Lenses were part of old stock kept at the ACO dispensing laboratory. The envelope has been re-used to store a different lens.SOLA (Scientific Optical Laboratories Australia) was founded in 1960. Its foundation was driven by the technical genius of Donald Schultz (See Watkins RD Profile of Donald Herbert Schultz Clin Exp Optom 2004; 87: 187-190) who had for some time been interested in the use of CR39 for the manufacture of ophthalmic lenses. SOLA became a highly successful international company for the production of CR39 lenses. CR-39, or allyl diglycol carbonate (ADC) was first used for spectacle lenses by Armorlite Lens Company in California in 1947.
