Tea is a broad category. Any specifics on what type?
From Consumer Reports review of the study:
“Hot tea, however, was found to have a potential benefit. (Iced tea, decaffeinated tea, and any kind of soda appeared to have no connection to changing one’s glaucoma risk.)”

So I would assume normal black hot tea, but it’s not a given.
