TRIAL OF ROYAL CANADIAN NAVY COLOUR VISION LANTERN IN COMPARISON WITH OTHER TESTS OF COLOR VISION

Abstract

Advantages of the Royal Canadian Lantern appear to be: (1) Simplicity of administration. Little training necessary. Results not influenced by individual operators whereas the Edridge-Green lantern requires considerable training and is difficult to administer. (2) Short test -- approximately 1 1/2 minutes per normal individual. (The American Optical Company (A-O) plates complete -- 1 1/2 + 3 minutes; Edridge-Green complete -- 3+ minutes). (3) simple to interpret and to score. Coaching or previous training has minor influence on results of lantern but marked influence on results of A-O plates. (4) Permits positive interpretation. (5) No special lighting required, therefore can always be given under standard conditions. A-O plates are seldom given under standard conditions, with consequent wide variance in results. (6) Less exacting in selection than A-O plates given and scored in accordance with existing instructions.
