Researchers from Dartmouth College and the University of St. Andrews have discovered that the eyes of reindeer appear to have evolved to allow them to easily spot their preferred meal, reindeer moss. Reindeer can see light in the ultraviolet spectrum, which is unusual among mammals and allows them to spot the dark patches of reindeer moss against the snow, even though these are hard for humans to see. The white lichen-like moss absorbs UV light, making it visible to reindeer. This unique vision gives reindeer an advantage in finding food, which is especially crucial in the harsh, cold landscapes they inhabit. This research has broadened understanding of how animals adapt to challenging conditions and has also suggested potential implications for human health, as reindeer eyes seem to protect them from UV light’s damaging effects.

One researcher also mentioned that reindeer’s eyes, full of ascorbic acid (vitamin C), are terrific for repairing damaged cells. The best treats for reindeer to protect the health of their eyes would be something rich in vitamin C, such as orange juice or carrots, which children should focus on rather than feeding the reindeer other high-calorie foods on Christmas Eve. Overall, the research has shed light on the unique vision of reindeer, its role in their hunting mechanism, and its possible human implications in terms of better understanding and treating diseases.
