Differences in human eye

The quantity and distribution of the pigment melanin in the iris of the eye determines eye colour. Brown and blue are the two dominant hues, with hazel, grey, and green appearing less frequently. Multiple genes all play a role in the diversity in eye colour, which is inherited genetically. Melanin is more concentrated in brown eyes compared to blue eyes.

Not only can different eye colours add to an individual's distinctiveness, but they also have cultural significance in diverse communities. Eye colour can affect how individuals view one another and can impact preferences and criteria for beauty.

Although heredity is the main determinant, environmental elements like age and light exposure can also have an impact on eye colour. Newborns
