Turville-Stewart Ophthalmoscope & Retinoscope

Historical Significance: A.E. Turville was an English optometrist and Dr Stewart an ophthalmologist whom Turville had met at a local radio society. They collaborated in the design of ophthalmic instruments. They had laboured in vain to make a table-mounted slit-lamp but, in the process, had learned a lot from the experience, which ultimately helped in their ophthalmoscope design. Turville and Stewart collaborated with the Ellis Optical Company of London to produce a series of ophthalmoscopes, including the Westminster and Wide-Angle models. Turville was a fellow of the British Optical Association. He founded an optometric practice in 1915 in Northhampton, London. He developed the Turville Infinity balance method of binocular refraction
