CNN: ‘All Human Eyes Are Brown’ (Video)
Humans may appear to have a range of eye colors such as blue and green. But a recent CNN article reveals that, contrary to this perception, all human eyes are brown.
The difference in color is the result of how much light is absorbed versus reflected out. Eyes with the least amount of melanin reflect the most light which can appear blue, whereas eyes with more of the pigment tend to appear green, hazel or brown.
The NIH also points out that, “While a child’s eye color can often be predicted by the eye colors of his or her parents and other relatives, genetic variations sometimes produce unexpected results.”
