Why are Afro-caribbean eyes different from Caucasian eyes?

Afro-caribbean eyes and Caucasian eyes are not inherently different. Eye colour is determined by the amount and distribution of melanin in the iris, and can vary greatly within both Afro-Caribbean and Caucasian populations. Melanin is a pigment that gives skin, hair, and eyes their colour. The amount of melanin in the iris determines eye colour, with more melanin resulting in darker eyes and less melanin resulting in lighter eyes. Other factors, such as genetics and environmental exposure, can also influence eye colour.

Overall, there is no scientific evidence to suggest that Afro-Caribbean eyes are inherently different from Caucasian eyes in terms of their basic structure or function. Eye colour variation within and between populations is a result of natural genetic diversity.
