A new Harvard study has discovered a high incidence of vision problems among men and women who drank three or more cups of coffee a day. The research, published in Investigative Ophthalmology & Visual Science
, linked heavy consumption of caffeinated coffee with increased likelihood of developing exfoliation glaucoma, an eye disorder that affects about 10 percent of adults over age 50 and can lead to vision loss or blindness.
Specifically, the researchers reported that adults who drank three or cups of coffee daily were 34 percent more likely to develop exfoliation glaucoma, compared to those who abstained from coffee. Women with a family history of glaucoma were at the highest risk, with their threat of exfoliation glaucoma soaring by 66 percent if they quaffed three or more cups of java per day.
Glaucoma, the second leading cause of blindness in the world, affects 60 million people. It is a group of painless diseases that can damage the optic nerve, if untreated. Typically, this damage results from increased pressure within the eye, usually due to fluid buildup.more
