Computer-based color vision tests offer an attractive alternative to traditional paper- or lantern-based tests. Classic tests for color vision typically rely on calibrated objects, such as printed pseudoisochromatic plates, color chips in the Farnsworth D-15 test, or a lamp in the Holmes-Wright Lantern Type A (HWA) test, which are costly and not easily distributed to participants. Computer-based tasks offer the potential for easier use, which could be beneficial in a range of settings. Almustanyir et al., assess the appropriateness of computer-based color vision tests for the assessment of pilot candidates in Canada. The authors find that the Konan-Waggoner D15 (KWC-D15) task would be an appropriate substitute for the F-D15 task, and the Color Assessment Diagnosis (CAD) or United States Air Force Cone Contrast Test (OCCT) could replace the HWA task; these are the two tests traditionally used to assess the color vision requirement to qualify for a Canadian pilot’s license. This study contributes to the evaluation of computer-based color vision tests, as these computer-based tests appear increasingly likely to become the gold standard. To be truly versatile in remote deployment, however, issues of calibration would need to be addressed, for the computer-based tests discussed here require displays to be color-calibrated with specialist equipment.
