Have you ever wondered why our eyes are structured the way they are? Take bees, for example; they can perceive ultraviolet radiation and see it. In contrast, human eyes and those of many other animals can only detect visible light. This is because the rays that our vision can perceive are more abundant on Earth than any others. So, what exactly is the light we see? It’s a transformed stream of energy from the sun’s core. Think of it as fragmented X-ray radiation and gamma photons generated in the sun’s depths, transformed into ultraviolet rays, and finally into the visible light we can see.
Over millions of years, Earth’s inhabitants have adapted their eyes to these rays, which have wavelengths ranging from 0.4 to 0.8 microns.
