Could a Hot Cup of Tea Preserve Your Vision?

THURSDAY, Dec. 14, 2017 (HealthDay News) -- A spot of hot tea in the afternoon might help you save your sight, new research suggests.

But the findings do raise a question that should be studied further, according to Coleman, a professor of ophthalmology at the University of California, Los Angeles.

Decaf tea and iced tea showed no relationship to the disease. Neither did coffee, caffeinated or not.
