Theory and practice of analytical refraction and orthoptics

Historical Significance: There are 3 editions of this book, 1939, 1943 and 1948. This book has an imprint date 1940 and is presumably a second printing of the first edition. Archive holds the revised edition of 1948 Cat No 181. Israel Dvorine (1900-1989) was an American optometrist who practised in the Baltimore area for 40 years. He never finished high school and worked first in an optical laboratory before completing his OD at Pennsylvania College of Optometry in the 1920s. He was named Optometrist of the Year by the AOA in 1983. This book was first published in 1939 and revised a number of times. It aligns itself with some of the OEP ideas about optometry. He states that emmetropia is an inadequate basis for the diagnostic and corrective techniques of refraction. He is perhaps best remembered as the designer of the Dvorine pseudoisochromatic plate test for colour blindness.
