A study in the scientific journal I-Perception indicates that reindeer possess a unique adaptation that causes their eyes to change color from gold in the summer to blue during the winter months. This unique phenomenon is due to a specific layer of tissue in the eye. This adaptation is crucial for reindeer, as it significantly improves their ability to see and navigate in the dark, snowy landscape. The shift to blue highlights the fascinating ways animals adapt to thrive in their environments.
