Drinking green tea may improve the health of your eyes. Laboratory tests showed antioxidants found in the drink can be absorbed deep inside the eye, helping to protect it against disease. Antioxidants are natural chemicals that neutralise free radicals, the potentially damaging molecules linked to disease. Green tea is rich in these and is said to have a wide range of health benefits, including fighting cancer.
Although previous studies have suggested green tea may reduce the risk of conditions such as glaucoma, new research confirms the eyes can actually absorb antioxidants from the blood. In the study, scientists measured levels in eye tissue. They found the retina, the area at the back of the eye where images are formed, soaked up the most while the cornea, the clear outer layer of the eye, absorbed the least (source: Daily Mail).
