Abstract

BACKGROUND

Previous studies have suggested that light rays may interact with contact lenses, potentially affecting their transmittance.

AIM

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，从而潜在地影响其透光率。

目的

本研究旨在探究可见光和紫外线（UV）-A光源对一些市售日抛、周抛和月抛隐形眼镜透光率的影响。

方法

用太阳模拟器、发光二极管（LED）光源、激光光源和UV-A光源照射9种市售软性隐形眼镜。使用安捷伦8453型紫外可见分光光度计测定受试镜片在紫外线、可见光和红外光波长范围内照射前后的平均透光率。

结果

结果显示，Bio true日抛隐形眼镜以及Acuvue Oasys、Avaira和Biomedics 55周抛隐形眼镜在UV-B区域（300 nm）和UV-A区域（355 nm）对紫外线传输有部分或完全阻挡。在可见光区域（555 nm），不同光源照射隐形眼镜导致透光率降低。在红外区域（900 nm），周抛和月抛隐形眼镜部分阻挡红外传输，而日抛隐形眼镜的红外传输则呈现增加或减少的情况。

结论

太阳光和人工照明以及高功率激光对隐形眼镜的光传输和光学性能构成主要影响。开发具有光防护性能同时保持可见光透光率的软性隐形眼镜至关重要。
