Historical Significance: Penrhyn Thomas (1918-2010) was a Sydney optometrist, who qualified in optometry at the Sydney Technical College in 1939 and was a prominent and influential pioneer of contact lens practice in Australia. He designed, produced and marketed his own lens designs and taught many optometrists how to fit contact lenses in the 1960s and 1970s. Penrhyn Thomas introduced the Conoid lens in 1967 which consists of a steep central optic with tangential peripheral curve. This is an early text book on contact lenses.
