Study finds dark chocolate might improve vision

Posted: Updated:

Dark chocolate may have a surprising health benefit.

A small study was led by researchers at the University of the Incarnate Word Rosenberg School of Optometry. The study found people had a slight improvement in their vision, two hours after eating a bar of 72-percent dark chocolate.

Previous studies suggest antioxidants in dark chocolate increase blood flow in the body, including to the eyes.
