This Eye Colour Linked to Higher Chance of Alcoholism

Link explained by similar set of genes coding for both eye colour and a tendency towards alcoholism.

People with blue eyes have a higher chance of becoming alcoholics, a new study finds.

In fact, light-coloured eyes in general — whether green, grey or brown — are more strongly linked to alcoholism.

In comparison, people with dark brown eyes have a lower chance of becoming alcoholics.

The connection is likely down to a similar set of genes coding for both eye colour and a tendency towards alcoholism.

Dr Dawei Li, one of the study’s authors, said:

“This suggests an intriguing possibility — that eye color can be useful in the clinic for alcohol dependence diagnosis.”

The study was published in the American Journal of Medical Genetics Part B: Neuropsychiatric Genetics (Sulovari et al., 2015).
