Good News! That Cup Of Coffee You’re Drinking May Make You Go Blind

And the vendetta against coffee continues. Why can’t caffeine ever catch a break?! Okay, so we recently wrote about all the ways coffee can help you at work and in life, but a new study is raining on our coffee-loving parade and telling us that too much coffee can cause us to go blind. Yeah, upsetting, I know. Don’t run away from your coffee cup in horror just yet. The study, The Relation between Caffeine and Coffee Consumption and Exfoliation Glaucoma or Glaucoma Suspect: A Prospective Study in Two Cohorts, is the first to examine this correlation, and says that “vision loss” and “blindness” is possible with heavy drinking of caffeinated coffee. The study found that heavy caffeine consumption is linked to an increased risk of “exfoliation glaucoma,” the leading cause of secondary glaucoma, which can lead to blindness.

This is admittedly very alarming, but more so, depressing.

Anyway, according to an article in sciencedaily.com, the study’s author, Jae Hee Kang, ScD, of Channing Division of Network Medicine at Brigham and Women’s Hospital in Boston, MA., said the research was sparked by the fact that “Scandinavian populations have the highest frequencies of exfoliation syndrome and glaucoma.”  The population also consumes the largest amount of caffeinated coffee in the world. Hence, the study was born.

Way to ruin it for the rest of us, Scandinavians!

The study was made up of more than 100,000 men and women who were at least 40 years of age and did not have glaucoma. The researchers used questionnaires to determine coffee consumption and medical records to determine incident cases of exfoliation glaucoma, which a person can develop without necessarily developing secondary glaucoma. They found, surprise, that subjects who drank more coffee had a higher risk of developing the syndrome. They did not find any links to other caffeinated beverages such as soda or tea.
