Study: eye color can increase risk of becoming an alcoholic

New research shows there's a link between eye color and your risk of becoming an alcoholic.

University of Vermont research shows the lighter your eyes are at the center, the higher your risk of getting hooked on alcohol. 

Blue eyes followed by greenish or grey eyes average an extra drink per month than their dark eyed counterparts. They face a great risk of dependency. 

The study was led by a doctoral student and Assistant Professor of Microbiology and Molecular Genetics Dr. Dawei Li. 

"We still don't know the reason," said Li in a news release. Li  says more research is needed.
