Some researchers claim to have uncovered a link between excess coffee consumption and the development of glaucoma – http://tinyurl.com/8wtt6sy
They analysed data collected from two studies involving 78,977 women and 41,202 men and found people who drank more than 3 cups of coffee a day had a higher incidence of glaucoma
While the results showed a . . .correlation between two variables (amount of coffee drunk and incidence of glaucoma) one cannot, from that, conclude that the former causes the latter, i.e., that these studies provide evidence to prove that drinking too much coffee increases the likelihood of an individual developing glaucoma
As a precautionary measure, however, you might want to play safe and reduce your daily coffee consumption if you are already at high risk of going blind because –
there is a history of glaucoma in your family and/or you’re a wanker!
Just saying ! 😉
