Green tea "is good for the eyes"

Green tea "is good for the eyes"

People who regularly drink green tea may benefit from improved vision, according to a new study.

Research published in the Journal of Agricultural and Food Chemistry showed that regular consumption of the substance is effective in penetrating the tissues of the eye, which could help fight glaucoma and other eye diseases.

Experts have long thought that antioxidants found in green tea, known as catechins, are capable of protecting the eye, but until now it was unknown whether they could actually penetrate the organ.

Study leader Chi Pui Pang said that the effects of the drink may last up to 20 hours, as the retina is the part of the eye which absorbs the highest concentration of catechins from the tea.

"Our results indicate that green tea consumption could benefit the eye against oxidative stress," the expert said.

It followed a recent study by scientists at the University of Florida in Gainesville found that specially-medicated contact lenses loaded with vitamin E can help to treat glaucoma.
