In an effort to increase flight safety, it is imperative to learn as much as possible about the man-goggle interrelationship. This study was undertaken to see if type of goggle or other covariates might affect visual acuity (VA). We tested the VA of 103 aircrew with both the AN/PVS-5 and Aviator's Night Vision Imaging System (ANVIS) goggles using a Snellen vision testing chart and the new Night Vision Goggle (NVG) Resolution (Grid Type) Chart. Average VA's using ANVIS (Snellen = 20/38, Grid = 20/45) were significantly better (p < 0.01) than VA's using AN/PVS-5 (Snellen = 20/54, Grid = 20/58). Snellen VA's were better on average than Grid VA's (p < 0.001). Neither age, gender, nor NVG experience affected average VA at the 0.05 level. Average VA was significantly better (p < 0.05) for non-spectacle wearers using ANVIS goggles and for non-smokers using AN/PVS-5 goggles. Visual acuity is better with ANVIS than with AN/PVS-5 goggles, and may be affected somewhat by wearing spectacles, and by smoking.
为提高飞行安全性，必须尽可能多地了解人与护目镜的相互关系。本研究旨在探讨护目镜类型或其他协变量是否会影响视力（VA）。我们使用斯内伦视力测试表和新的夜视护目镜（NVG）分辨率（网格型）图表，对103名机组人员佩戴AN/PVS - 5和飞行员夜视成像系统（ANVIS）护目镜时的视力进行了测试。使用ANVIS时的平均视力（斯内伦视力表 = 20/38，网格型 = 20/45）显著优于使用AN/PVS - 5时的平均视力（斯内伦视力表 = 20/54，网格型 = 20/58）（p < 0.01）。平均而言，斯内伦视力表测得的视力优于网格型视力（p < 0.001）。在0.05的显著水平下，年龄、性别和NVG使用经验均未影响平均视力。使用ANVIS护目镜的非眼镜佩戴者和使用AN/PVS - 5护目镜的非吸烟者的平均视力显著更好（p < 0.05）。ANVIS护目镜的视力优于AN/PVS - 5护目镜，并且可能会受到佩戴眼镜和吸烟的一定影响。
