Gulp down this zero-calorie refresher and it could pay some unexpected dividends for your vision. We're talking about green tea.
A new lab study suggests that the flavonoids in this steamy drink may offer protection against a host of vision problems, including cataracts, age-related macular degeneration, and possibly even some forms of glaucoma.
Peeper Protector
One particular flavonoid found in green tea -- called gallocatechin -- may be particularly good for eyes. Studies show it tends to accumulate in the retina. And that's a good thing because flavonoids in your retina function like bionic sunscreen, protecting fragile cells against the sun's damaging rays. It's the same way that other vision-friendly flavonoids found in spinach, kale, and orange peppers operate. They also tend to concentrate in your eyes and protect your retinas.

Edible Sunscreen
More research is needed to confirm whether green tea truly does have an eye-friendly function, but the good news is that it probably doesn't take much to experience positive effects. Still, at least a daily helping would be best. In the study, a single "dose" offered protection for about 20 hours. (Time for a peeper check?
