Abstract：
BACKGROUND: Previous studies have suggested that light rays may interact with contact lenses, potentially affecting their transmittance.
OBJECTIVE: This study aimed to investigate the effects of visible and ultraviolet (UV)-A light sources on the transmittance of some commercially available daily, weekly, and monthly contact lenses.
METHODS: Nine commercially available soft contact lenses were irradiated with a solar simulator, light-emitting diode (LED) source, laser source, and UV-A source. The average transmittance of the tested lenses before and after irradiation in the UV, visible, and infrared light wavelength ranges was determined using an Agilent UV-visible spectrophotometer, model 8453.
RESULTS: The results showed a partial or complete block of UV transmission at the UV-B region (300 nm) and the UV-A region (355 nm) by the Bio true daily contact lens, as well as the Acuvue Oasys, Avaira, and Biomedics 55 weekly lenses. At the visible region (555 nm), irradiation of the contact lenses by different light sources resulted in reduced light transmittance. At the infrared region (900 nm), the weekly and monthly contact lenses partially blocked infrared transmission, while the daily lenses showed either increased or decreased infrared transmission.
CONCLUSIONS: Solar and artificial lighting, as well as high-powered lasers, constitute a major concern on the contact lenses\' light transmission and optical properties. It is essential to develop soft contact lenses that have photoprotective properties while maintaining visible light transmittance.

摘要：
背景：先前的研究表明，光线可能与隐形眼镜相互作用，可能会影响其透射率。
目的：本研究旨在研究可见光和紫外线（UV）-A光源对一些市售日常透光率的影响，每周,和每月隐形眼镜。
方法：用太阳模拟器照射九种市售软性隐形眼镜，发光二极管（LED）源，激光源,和UV-A源。受测镜片在紫外线照射前后的平均透射率，可见,使用安捷伦紫外可见分光光度计确定红外光的波长范围，模型8453。
结果：结果显示，Bio真正的日常隐形眼镜在UV-B区域（300nm）和UV-A区域（355nm）处的UV透射部分或完全阻断，以及AcuvueOasys,Avaira,和生物55每周镜片。在可见光区（555nm），不同光源照射隐形眼镜导致透光率降低。在红外区域（900nm），每周和每月的隐形眼镜部分阻挡了红外透射，而日常镜片显示红外透射率增加或减少。
结论：太阳能和人工照明，以及高功率激光器，构成对隐形眼镜的光透射和光学特性的主要关注。开发具有光防护性能同时保持可见光透射率的软接触透镜是必要的。
