Drinking at least three cups of coffee a day could increase your risk of glaucoma, according to a new study.

Harvard University researchers say while there are some health benefits to drinking caffeinated coffee, drinking three or more cups increases the risk of glaucoma by 66 percent.

The study did not find the same link with other caffeinated products such as tea, chocolate or soda.

The report analyzed data from earlier studies on almost 79,000 American women and 41,000 men.
