Yellow filter glasses, often sold as "antifog" or "safety" glasses at department stores and other retail outlets, are claimed to improve contrast sensitivity and the yield of visually perceived objects, particularly under poor conditions (e.g., fog, rain and twilight), by enhancing contrast. These claims were tested in 15 healthy subjects (30 eyes) aged 26 to 58 (mean 42.5) years with the Vision Contrast Test System (VCTS 6500), first with and then without yellow filter glasses. Testing was done with commercial antifog glasses and frame-mounted, hand-held filter glasses of CR (Columbia resin) 39 quality with a yellow tint made by an optician. Contrast sensitivity was found to be significantly improved with yellow filter glasses (p less than 0.0001). The use of yellow filter glasses may safely be recommended to patients who report subjective improvement in contrast vision with such glasses.
黄色滤光眼镜常在百货商店及其他零售店作为“防雾”或“安全”眼镜出售,据称通过增强对比度可提高对比敏感度以及视觉感知物体的清晰度,尤其是在恶劣条件下(如雾天、雨天和黄昏)。使用视觉对比测试系统(VCTS 6500)对15名年龄在26至58岁(平均42.5岁)的健康受试者(30只眼)进行了测试,先佩戴黄色滤光眼镜测试,然后不佩戴测试。测试使用了商业防雾眼镜以及由配镜师制作的带有黄色色调的CR(哥伦比亚树脂)39质量的镜框式手持滤光眼镜。结果发现,佩戴黄色滤光眼镜时对比敏感度显著提高(p小于0.0001)。对于那些表示佩戴此类眼镜后主观上对比视力有所改善的患者,可安全推荐使用黄色滤光眼镜。
