Appliance of Science: 'Why do people have different-coloured eyes?'

Sábha, is ten and she lives in Bray with her parents and twin sister, Lile, and she has a wonderful scientific mind. Sábha would like to know… “Why do our eyes have colour and why do different people have different coloured eyes?”
