The Unique Reason Reindeer Change Their Eye Color

The video explains how certain animals, like reindeer, have a special eye tissue called tapetum lucidum that reflects light, aiding in low-light vision. Reindeer uniquely change their eye color seasonally, from gold in summer to blue in winter, to adapt to Arctic light conditions. This color change is due to the compression of collagen fibers in their eyes, which affects light reflection and absorption, enhancing their ability to see in darkness but causing slightly blurred vision.
