Tinted and ultraviolet (UV)-blocking disposable contact lenses have become increasingly popular over the last decade. Wearers of UV-blocking contact lenses could benefit greatly by protecting their eyes from potential UV radiation damage. A Uvikon 930 dual beam spectrophotometer was used to measure three enhancement-tinted lenses (royal blue, evergreen, and aqua), two types of UV-blocking lenses, and two types of non-UV-blocking lenses. Enhancement-tinted lenses did show a decrease in transmittance at certain wavelengths on the visible spectrum, but they did not reduce the transmittance of UV radiation to the extent of the UV-blocking lenses designed specifically for this purpose.
在过去十年中，有色且能阻挡紫外线（UV）的一次性隐形眼镜越来越受欢迎。佩戴能阻挡紫外线的隐形眼镜可使眼睛免受潜在的紫外线辐射伤害，从而带来极大益处。使用一台Uvikon 930双光束分光光度计对三种增色镜片（宝蓝色、翠绿色和水绿色）、两种类型的防紫外线镜片以及两种类型的非防紫外线镜片进行了测量。增色镜片在可见光谱的某些波长处确实显示出透光率下降，但它们并未像专门为此设计的防紫外线镜片那样降低紫外线辐射的透光率。
