(CNN) - Coffee lovers beware: a new study shows drinking at least three cups of joe a day could increase your risk of glaucoma.
Researchers found your risk of getting a certain type of glaucoma, called exfoliation glaucoma, goes up 66 percent if you drink more than three cups of caffeinated coffee a day. The same result was not found in other caffeinated beverages such as soda or tea.
The lead researcher says the results still need to be confirmed through more studies.
