Researcher states that healthy components of green tea could get into the eye tissue and acts as an antioxidant in the area.
Green tea has been claimed to have some positive benefits, like fighting heart disease and cancer. This effect comes from the antioxidant content of catechins in it.
Catechins, bright researchers, is one of a number of antioxidants (including vitamin C, vitamin E, lutein and zeaxanthin), which is believed to help protect the soft tissues of the eye disease glaucoma and other eye disorders. But it did not previously known whether the catechins in green tea can be absorbed into the eye tissue.
In a study published in the Journal of Agricultural and Food Chemistry, the researchers fed laboratory mice with green tea extract. Then the researchers analyzed the mouse eye tissue.
Results showed that certain parts of the eye in the amount of catechins absorb different. The retina is the eye area with the highest content of catechins. The retina is the light sensitive tissue lining the back of the eye. Cornea was part of the least absorbed catechins. The cornea is the outermost layer of the eye.
Antioxidants
In addition, the study also found that the level of antioxidant activity lasted for 20 hours after drinking green tea extracts.
These findings, according to researchers from Kai On Chu, Chinese University of Hong Kong showed that green tea can protect the eyes. “However, further study is needed to prove this positive effect on human,” explains Chu.
