Can too much caffeinated coffee really harm your vision?

Personally, I am not big coffee drinker. However, I can appreciate a nice cappuccino or hot chocolate on a chilly day, but it is nowhere near a necessity to get through the day. One research study has found that people who drink a lot of caffeinated coffee are at higher risk of developing a particular form of glaucoma called exfoliation glaucoma. This condition affects nearly 10 percent of 50-plus adults, and the study showed that heavy coffee drinking can increase the risk by 66%. Female subjects who had a family history of glaucoma were the most at risk. If you are a heavy coffee drinker now in your youth, odds are that you wont kick coffee to the curb when you get older, possibly increasing your risk for exfoliation glaucoma. What is your risk for this condition? Is this enough to deem caffeinated coffee bad for you?
