Beware of the Adverse Effects of Coffee On Your Eyes
From the many benefits of coffee, it sounds like you should start to limit coffee consumption in normal doses. Recent research from Harvard University revealed that excess coffee can increase the risk of eye damage resulting in blindness.
Caffeine is known as material related with eye disorder called exfoliation glaucoma. “Drinking three cups of coffee or more a day, is found to be associated with increased interference in glaucoma, especially for those who have a family history of glaucoma,” said Jae Hee Kang, assistant professor of medicine at the Channing Division of Network Medicine at Brigham and Women’s Hospital in Boston.
“Those who are at risk of these disorders, especially those with a family history of glaucoma are strongly encouraged to limit their intake of coffee, less than three cups per day,” he said, as quoted by ScienceDaily.
The study involved 79 thousand women respondents, by taking health data, including the results of eye examination, and a questionnaire to determine how much coffee they consume in a day. In a previous study, Kang noted that Scandinavia is a top ranking for the case of eye disorders caused by coffee. They are proven to consume three cups of coffee or more in a single day.
This eye disorder characterized by an emphasis on the eyeball. If this condition persists, it will possibly cause more damage to the optic nerve around the eyes. This causes permanent blindness. The more caffeine you consume, increase the risk of eye damage.
