Coffee is good for a whole lot of things, but I guess too much of a good thing can possibly lead to something not so good. A recent study at Harvard has linked having three or more cups of coffee per day to a slight increased risk of developing exfoliation glaucoma.
The study examined 78,977 women in a Nurses’ Health Study and 41,202 men in the Health Professionals Follow-up Study. All of the participants were over 40 years old and none of them suffered from glaucoma. All of them had received eye exams from 1980 through 2008 according to Science Daily. All participants participated in health questionnaires.
Exfoliation glaucoma is caused by tiny white flakes that build up on the lens of the eye, according to the Medical Daily. The buildup causes pressure inside the eye. Its generally linked to 10% of people over 50 years old. Exfoliation glaucoma can lead to everything from vision loss to blindness.
“If the findings are confirmed,” study author Jae Hee Kang, ScD, from Brigham and Women’s Hospital in Boston said, according to Yahoo! Health, “those at risk of exfoliation glaucoma—particularly those with a family history, would be recommended to limit their intake of coffee to less than three cups per day.”
