According to a study made by researchers from the University of California, people who drink tea at least once a day “are 74 percent less likely” to be diagnosed with glaucoma, a disease which affects an estimated 2.72 million people in the U.S. alone.
Interestingly enough, researchers found that coffee, tea, and soft drinks do not have the same effect as tea.
Glaucoma is a condition wherein fluid pressure builds up inside the eye (interocular pressure), which in turn, can damage the optic nerve. According to the World Health Organization, the condition is the second leading cause of blindness worldwide.
The study, which was published in the British Journal of Opthalmology, used data from the 2005-2006 National Health and Nutrition Examination Survey (NHANES), an annual survey done in the U.S., which compiled data and tests in order to provide an accurate picture of the health and nutritional status of adults and children. Among the 10,000 samples in the NHANES, at least 1,678 participants were able to have full eye test results, with 84 adults noted to have developed the condition.
Data were then gathered to indicate their drinking habits, particularly when it comes to caffeinated and decaffeinated drinks, using a questionnaire. Results indicated that almost half of the participants had reported drinking coffee often; however, only less than 10 percent drank hot tea daily.
“Tea drinkers should keep drinking and don’t need to stop because of a fear of glaucoma,” lead author Dr. Anne Coleman said. “This makes sense, but we’ll see if it holds up in future studies.”
