The antioxidants in green tea are known to prevent cancer and promote good heart health, but a study has just been published that shows that green tea has the potential to heal eye ailments, like glaucoma.
According to the LA Times Booster Shots blog (Study: Green tea could heal glaucoma), researchers in Hong Kong have found that the healthy compounds in green tea called catechins are absorbed readily by the eye as by other parts of the body. The highest concentration of catechins were found in the retina. While this study was conducted on mice, further research will be needed to determine the exact amount of green tea needed to boost eye health in humans.
The science is in its earliest stages, but it seems quite likely that the eye can benefit just as much from green tea as your body can overall.
