Drinking a cup of hot tea at least once a day may be linked to a significantly lower risk of developing the serious eye condition, glaucoma, finds a small study published online in the British Journal of Ophthalmology.
But drinking decaffeinated and caffeinated coffee, decaffeinated tea, iced tea and soft drinks doesn't seem to make any difference to glaucoma risk, the findings show.
[...] After taking account of potentially influential factors, such as diabetes and smoking, hot tea-drinkers were 74 per cent less likely to have glaucoma.
But no such associations were found for coffee -- caffeinated or decaffeinated -- decaffeinated tea, iced tea or soft drinks.
This is an observational study so no firm conclusions can be drawn about cause and effect, and the absolute numbers of those with glaucoma were small. Information on when glaucoma had been diagnosed was also unavailable.

Haha. Just what I was thinking. I usually have a cup of tea, earl grey, hot to start the day, then switch to green tea in the afternoon (which has less caffeine), and finally green herb in the evening. It sounds like I can rest assured I will never be at risk for glaucoma!
