It turns out that bees don’t just have two eyes—they have thousands. “Bees’ eyes are very different from human eyes,” George Kolyfetis, a graduate student in the Department of Biology at the University of Konstanz, tells Popular Science. The bees’ dorsal ommatidia are on the top of their eyes and always pointed in the sky. Interestingly, the dorsal ommatidia’s light-detecting cells are less sensitive than other ommatidia, protecting bees from the sky’s blinding sunlight, but also hiding its details. In the future, human-made bee eyes could even bolster autonomous navigation systems.
