Drinking at least three cups of caffeinated coffee a day increases the risk of developing glaucoma, according to a study reported in Investigative Opthalmology and Visual Science.

Researchers monitored 78,977 women and 41,202 men between 1980 and 1986 to 2008. Drinking at least three cups of caffeinated coffee a day increased risk of confirmed/suspected exfoliation glaucoma (cellular debris blocks the trabecular meshwork, through which fluid drains from the eye) by 66 per cent (relative risk [RR] 1.66), when compared with those who drank no caffeinated coffee. Here, 21 per cent of women and 12 per cent of men drank at three cups of caffeinated coffee daily.
