前言 据军队飞行员报告,戴塑料太阳镜时很难分辨驾驶舱内预警灯的颜色。这可能是由于镜片太暗,或因并非灰色而改变了色觉。运用物理学和心理学方法对这个问题的根源进行了鉴定,介绍了答案,确定了视觉性能最佳的太阳镜的光导性。方法 由7个军队光学实验室各订做5副塑料太阳镜(-4～+4D,总共70个镜片),通知每个实验室将镜片染为透光度为 According to military pilots, it is hard to distinguish the color of warning lights in the cockpit when wearing plastic sunglasses. This may be because the lens is too dark, or because it is not gray to change the color vision. The use of physical and psychological methods to identify the root causes of this problem, introduced the answer to determine the best visual performance of the photoconductivity of sunglasses. Methods Five optical plastic lenses (-4 ~ + 4D, 70 lenses in total) were made by 7 military optical laboratories, and each laboratory was instructed to dye the lens into a light transmittance of
