The Science Behind Eye Color | Why Humans Have Different Eye Colors

Eye color is determined by the amount and distribution of Melanin within the Iris. Higher melanin levels produce darker eyes such as brown, while lower levels scatter light and create lighter shades like blue. Genetic variations also influence eye colors such as hazel, amber, and gray.
In this short video, discover the fascinating biology and science behind human eye color.

00:00Eye color isn't just about blue, brown, or green.
00:03It all comes down to a pigment called melanin inside the iris.
00:07More melanin creates darker eyes, like brown,
00:10while less melanin allows light to scatter,
00:13producing lighter shades like blue.
00:15Interestingly, blue eyes don't contain blue pigment at all.
00:20Instead, they appear blue because of how light interacts with the structure of the iris.
00:25Eye color is determined by multiple genes,
00:28which is why siblings can have different shades.
00:31Even subtle variations in melanin can create hazel, amber, or gray eyes,
00:36making each person's gaze truly unique in surprising ways.
