Historical Significance: This trial lens set almost certainly belonged to Ernst Goetz (1903-1979) who was born in Switzerland and studied optometry in Jena, Germany, obtaining his Masters certificate in optometry and his diplom-optiker in 1924. He emigrated to Australia in 1924 to join his girlfriend and became a sales representative for Zeiss in Melbourne and joined Alfred Nott as an optometrist in 1926. He practised in Collins Street and subsequently purchased the practice in 1940. He was probably the first Australian optometrist to fit contact lenses and also the first to prescribe telescopic low vision aids. He had learned about both during his studies in Jena, the town in which Carl Zeiss was located. Zeiss pioneered both contact lens manufacture and low vision aids. Trial sets of 39 afocal lenses were produced in 1930. This set may be a variation of those sets. Not all the lenses in the set are original.
