Visual acuity and color vision were tested during a search and rescue exercise at sea. Fifty-seven watchkeepers searched for orange and yellow life rafts during daylight and for lighted and unlighted life rafts at night with night vision goggles. There were 588 individual watches of one hour each. Measures of wind, waves, and weather were used as covariates. Daytime percentage detection was positively correlated with low-contrast visual acuity and negatively correlated with error scores on Dvorine pseudoisochromatic plates and the Farnsworth color test. Performance was better during the first half-hour of the watch. Efficiency calculations show that color vision selective screening at one standard deviation above the mean would increase daylight search performance by 10% and that one standard deviation visual acuity selection screening would increase performance by 12%. There was no relationship between either acuity or color vision and life raft detection using night vision goggles.
在一次海上搜救演习中测试了视力和色觉。57名值班人员在白天搜索橙色和黄色救生筏,夜间使用夜视镜搜索有灯光和无灯光的救生筏。共有588次时长为一小时的单独值班。风速、浪高和天气状况被用作协变量。白天的探测百分比与低对比度视力呈正相关,与Dvorine假等色板和 Farnsworth 颜色测试中的错误分数呈负相关。在值班的前半小时表现更好。效率计算表明,在高于平均值一个标准差的水平上进行色觉选择性筛查将使白天搜索性能提高10%,在高于平均值一个标准差的水平上进行视力选择筛查将使性能提高12%。使用夜视镜进行救生筏探测时,视力或色觉与探测结果之间没有关系。
