A highway study of clear, tinted and photochromic prescription spectacles was conducted using a 58-mile driving course marked with 130 randomly spaced transverse white stripes. The data of 29 subjects totaling more than 21,000 stripe detection events showed that coated photochromic prescription lenses performed better by day and poorer by night compared to uncoated white crown prescription lenses, and that a multiple-layer coated, tinted lens (Neo Multicoat) performed at least as well, day or night, as did the uncoated white crown lens.
利用一条58英里长、标有130条随机分布横向白色条纹的驾驶路线，对透明、有色和光致变色处方眼镜进行了一项公路研究。29名受试者的数据总计超过21000次条纹检测事件表明，与未镀膜的白冠处方镜片相比，镀膜光致变色处方镜片在白天表现更好，而在夜间表现较差；并且一种多层镀膜的有色镜片（Neo Multicoat）在白天或夜间的表现至少与未镀膜的白冠镜片一样好。
