Our visual perception of the world - seeing form and colour or navigating the environment - depends on the interaction of light and matter in the environment. Light also has a more fundamental role in regulating rhythms in physiology and behaviour, as well as in the acute secretion of hormones such as melatonin and changes in alertness, where light exposure at short-time, medium-time and long-time scales has different effects on these visual and non-visual functions. Yet patterns of light exposure in the real world are inherently messy: we move in and out of buildings and are therefore exposed to mixtures of artificial and natural light, and the physical makeup of our environment can also drastically alter the spectral composition and spatial distribution of the emitted light. In spatial vision, the examination of natural image statistics has proven to be an important driver in research. Here, we expand this concept to the spectral domain and develop the concept of the 'spectral diet' of humans.
我们对世界的视觉感知——看到形状和颜色或在环境中导航——取决于环境中光与物质的相互作用。光在调节生理和行为节律以及褪黑素等激素的急性分泌和警觉性变化方面也具有更基本的作用，在短时间、中等时间和长时间尺度上的光照对这些视觉和非视觉功能有不同影响。然而，现实世界中的光照模式本质上是杂乱无章的：我们进出建筑物，因此会接触到人造光和自然光的混合光，而且我们环境的物理构成也会极大地改变所发射光的光谱组成和空间分布。在空间视觉方面，对自然图像统计数据的研究已被证明是该领域研究的一个重要驱动力。在此，我们将这一概念扩展到光谱领域，并提出人类“光谱饮食”的概念。
