The modern treatment of binocular balances

Historical Significance: Peckham was an optometrist in Connecticut, USA who may have had some contact with Adelbert Ames. A paper by RR Behrens on the Life and unusual ideas of Adelbert Ames in Leonardo 1987 20(3) 283-279 refers to Dr Ray Morse Peckham 'who lived in Conneticut in the 1920s and practised optometry' and became friendly with Ames and worked with him on some of Ames experiments. Peckham seems to have been one of those enthusiastic thinkers and teachers in optometry with a gift for writing. He published a number of books including Binocular balance and the Genothalmic Kratometer : a lecture delivered at the office of General Optical Company, Inc., Boston, Mass. ca. 1925; Binocular balance 1926; The modern treatment of ocular imbalances with the genothalmic kratometer 1926; The non-operative correction of squint : manual of instruction for the Squint-Korector 1930; The study of eye-movements during alternation in binocular vision, 1933; Home study course in practical optometry 1932; Binocular balance and A home study course in practical optometry 1926-32; The principles of binocular fusion and stereoscopic vision. 1940. The Kett Museum holds several of these books.
