Scientists Studied People With Green Eyes — They Weren’t Prepared for What They Found

Green eyes are among the rarest eye colors in the world, and scientists have long studied the genetics and biology behind this unusual trait. Unlike simple eye-color categories, green eyes result from a complex combination of pigmentation, light scattering, and genetic variation. In this video, we explore what researchers have discovered about people with green eyes, including their genetics, ancestry, visual characteristics, and why this eye color is so uncommon. Some of the findings may be far more surprising than you expect.
