Ultraviolet (UV) radiation (UVR) has well-known adverse effects on the skin and eyes. Little attention is given to physical means of photoprotection, namely glass, window films, sunglasses, and clothing. In general, all types of glass block UV-B. For UV-A, the degree of transmission depends on the type, thickness, and color of the glass. Adding window films to glass can greatly decrease the transmission of UV-A. Factors that can affect the transmission of UVR through cloth include tightness of weave, thickness, weight, type of fabrics, laundering, hydration, stretch, fabric processing, UV absorbers, color, and fabric-to-skin distance.
紫外线（UV）辐射对皮肤和眼睛有众所周知的不良影响。人们很少关注光防护的物理手段，即玻璃、窗膜、太阳镜和衣物。一般来说，所有类型的玻璃都能阻挡UV-B。对于UV-A，其透过程度取决于玻璃的类型、厚度和颜色。给玻璃贴上窗膜可以大大降低UV-A的透过率。影响紫外线透过衣物的因素包括织物的紧密程度、厚度、重量、织物类型、洗涤、水合作用、弹性、织物加工、紫外线吸收剂、颜色以及织物与皮肤的距离。
