A new American study calls on coffee lovers to cut down on the black drink. Researchers have found a link between coffee and glaucoma.
According to researchers, people who drink at least three cups of coffee a day, the risk of developing glaucoma (glaucoma), which can lead to impaired vision or blindness.
Researchers from Harvard University, the United States has followed around 120,000 persons over 40 years from the 1980s to 2008, who had no signs of glaucoma, and asked for their coffee habits.
Among those who daily drank coffee, was the likelihood of developing precancerous glaucoma, also called exfoliation glaucoma, significantly higher compared with those who drank coffee – in particular in persons with glaucoma in the family.
Exfolation glaucoma is characterised by the pigments in the eye that river loose and blocking the drain of the fluid in the eye. It creates increased pressure within the eye and can affect the optic nerve cells at the back of the eye and thus reduce the eyesight. Eye disease is mostly prevalent among the older segment of the population.
There is, however, not found the same correlation among other caffeinated products such as soft drinks, tea or chocolate.
