Only if you have 3 cups a day or more according to a new Harvard study.  The study found that men and women who were excessive (caffeinated) coffee drinkers, had an increased chance of developing exfoliation glaucoma, an eye disorder that can lead to loss of vision, according to the article.

Scary stuff, but what can us coffee lovers do? 
Switch to decaf! 
It's not all doom and gloom though.  Other studies have shown that coffee drinkers have a lesser chance of developing liver cancer and a lower possibility of colon, breast and rectal cancer than those who don’t drink the energizing beverage.
I'll take my chances... everything in moderation.
