发光二极管（led）已被用于工业和商业环境中提供照明。led也用于电视、电脑、智能手机和平板电脑。虽然大多数led发出的光是白色的，但led的峰值发射在蓝光范围内（400-490 nm）。越来越多的实验证据表明，蓝光照射可影响许多生理功能，可用于治疗昼夜节律和睡眠功能障碍。然而，蓝光也会引起光感受器损伤。因此，重要的是要考虑基于led光源的光谱输出，以尽量减少可能与蓝光暴露有关的危险。本文就蓝光对人体生理功能的调节作用以及蓝光对眼健康可能产生的影响等方面的研究进展进行综述。
Light-emitting diodes (LEDs) have been used to provide illumination in industrial and commercial environments. LEDs are also used in TVs, computers, smart phones, and tablets. Although the light emitted by most LEDs appears white, LEDs have peak emission in the blue light range (400–490 nm). The accumulating experimental evidence has indicated that exposure to blue light can affect many physiologic functions, and it can be used to treat circadian and sleep dysfunctions. However, blue light can also induce photoreceptor damage. Thus, it is important to consider the spectral output of LED-based light sources to minimize the danger that may be associated with blue light exposure. In this review, we summarize the current knowledge of the effects of blue light on the regulation of physiologic functions and the possible effects of blue light exposure on ocular health.
