Description
A cream coloured hinged-lid rectangular box with two metal clasps at the front. There is black printed text in the centre of the lid which reads “HIRST / CON-O-COID / TRAIL SET”. Inside is a plastic tray with four rows of circular holes that contain contact lenses. Each hole has a different measurement number. Under “E.9”, the first two rows have sequential numbers from 7.2 to 8.2. Under “E.10” the second two rows of numbers also range from 7.2 to 8.2. Each numbered hole holds a contact lens except 7.6 and 7.7 in the third row. There are 20 lenses in total. There is also a hand-written card in the box which reads “The first / Conocoid / Set / 1966”.
This is a PMMA contact lens trial set used by Optometrists circa 1968. The Con-o-coid contact lens design was developed by Hirst in conjunction with Dr David Volk. Due to licensing issues circa 1984 the design was instead referred to as the Aspheric contact lens.
