Historical Significance: Kratometer (kra?tom?e?ter) is a prism-refracting instrument for use in orthoptic training. The General Optical Company also made one, an example of which is held by College of Optometrists London (pictured) see http://www.museyeum.org/detail.php?t=objects&type=all&f=&s=kratometer&record=0. See also the 'Modern Treatment of Binocular Imbalances with the Genothalmic Kratometer' by Ryer, LeRoy and Peckham. Shur-On Optical Co. (1928). The instrument and the book are illustrative of the enthusiasm for binocular vision in the first half of the 20th C. The archive has a Kratometer. See Cat No 913.
