This book was released on 1973 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Subjects of varying type and degree of color deficiency were tested on a battery of color tests, including the American Optical Company Plates (both 1940 and 1965 editions), the Dvorine Plates, the Farnsworth-Munsell 100-hue, the Farnsworth Lantern, the Farnsworth Panel D-15, the SAM Color Threshold Tester, the Titmus Vision Tester Color Plate, and an anomaloscope. Correlations with a daytime and nighttime practical test of the ability of subjects to discriminate aviation signal red, white, and green were obtained. The results indicate that color defective people can identify flashes from a signal light gun better at night than during the day. It was also found that the Farnsworth Lantern, the SAM Color Threshold Tester, the two sets of A O Plates, and the Dvorine Plates were among the best predictors of performance on the practical test; the Titmus Plate was the poorest predictor.

Book Color Defective Vision and Day and Night Recognition of Aviation Color Signal Light Flashes

Download or read book Color Defective Vision and Day and Night Recognition of Aviation Color Signal Light Flashes written by Jo Ann Steen and published by . This book was released on 1971 with total page 14 pages. Available in PDF, EPUB and Kindle. Book excerpt: A previous study reported on the efficiency with which various tests of color defective vision can predict performance during daylight conditions on a practical test of ability to discriminate aviation signal red, white, and green. In the current study, subgroups of the subjects used in the previous investigation were tested with the signal light gun at night. Comparisons of the efficiency of each of seven tests of color defective vision in predicting performance under day and night conditions are reported.

Book Validity of FAA approved Color Vision Tests for Class II and Class III Aeromedical Screening

Download or read book Validity of FAA approved Color Vision Tests for Class II and Class III Aeromedical Screening written by Nelda J. Milburn and published by . This book was released on 1993 with total page 14 pages. Available in PDF, EPUB and Kindle. Book excerpt: All clinical color vision tests currently used in the medical examination of pilots were studied regarding validity for prediction of performance on practical tests of ability to discriminate the aviation signal colors, red, green, and white given under both day and night conditions. Those same practical tests are given to pilots with color vision deficiency who apply for a waiver of the Class II or Class III color vision standards. Subjects with varying type and degree of color vision deficiency (n=122) and subjects with normal color vision (n=120) were classified with the anomaloscope and given both practical and clinical tests. The clinical color vision tests included the American Optical Company plates (1965 and 1940 Editions), AOCHRR plates (2nd Edition), Ishihara plates (14-, 16-, 24-, and 38-plate tests), Dvorine plates, Richmond plates, Farnsworth Lantern, School of Aviation Medicine Color Threshold Tester, Titmus Tester, Titmus II Tester, OPTEC 2000 Tester, and Keystone Orthoscope/Telebinocular test. The criterion tests required naming the colors of actual signals produced by the Aviation Signal Light, with the same test procedures and viewing distances used in actual practical tests. The Farnsworth Lantern and several plate tests were the best clinical tests for predicting ability to identify the colors of aviation signals. Individuals with color vision deficiency identified signal colors better at night than during the day. Recommendations for improving the disposition criteria of some clinical tests, and for discontinuing several obsolete tests are discussed.

Book Color Defective Vision and the Recognition of Aviation Color Signal Light Flashes

Download or read book Color Defective Vision and the Recognition of Aviation Color Signal Light Flashes written by Mark F. Lewis and published by . This book was released on 1971 with total page 13 pages. Available in PDF, EPUB and Kindle. Book excerpt: Subjects of varying type and degree of color deficiency were tested on a battery of color tests, including the American Optical H-R-R plates, the Dvorine plates, the Color Threshold Tester, the Farnsworth-Munsell 100-hue, the Farnsworth Panel D-15, the Titmus Vision Tester Color Plats, and an anomaloscope examination. Correlations with a practical test of the ability of subjects to discriminate aviation signal red, white, and green were obtained. The results generally indicated that the Farnsworth Lantern was a superior predictor of performance on the practical test.
