Green Tea to Protect Your Eyes and Eyesight
There are no natural products, which have greater popularity than green tea.
Its health benefits seem to be all-encompassing and further evidence for this comes from the science labs almost
every day. We know that green tea can prevent cancer, heart disease and diabetes by having a beneficial effect on
various tissues in the body. However, the eyes are more specific organs given the types of cells they have and
their structure. Hence, it is worth asking whether green tea can be used for protection from eye and
A recent study, carried out in Japan in early 2010, revealed that the powerful antioxidants in green tea
can be affectively absorbed by the eye tissues. The scientists discovered that the highest
concentration of catechins was in the retina and the lens, which are more important for vision and more
vulnerable, at the same time. Another beneficial effect, which the study revealed, is that the catechins can remain
active for some 20 hours after they have reached the eyes.
Generally, this study has confirmed that powerful antioxidants from green tea, such as lutein, zeaxanthin and
Vitamins C and E, can exercise their positive effect on the eyes. The catechins combat the free radicals that
damage the cells and their DNA. Thanks to their action, common diseases, like glaucoma, can be prevented.
In addition, since the antioxidants have an anti-aging effect, it is possible for them to prevent other types of
eye diseases, associated with aging. Once study in Oxford University in the UK has revealed that
epigallocatechin gallate (EGCG), a powerful catechin abundant in green tea,
reduces the damage from free radicals 10 times better than Vitamin E. The scientists have
concluded that EGCG can prevent the degeneration of the retina caused by aging. There is even
evidence that green tea can prevent the formation of cataracts in the eye, even though the experiments were carried
out on laboratory rats.
A different study on the benefits of green tea for the eyes concluded that EGCG provides better protection
against UV damage. The antioxidant can stimulate the production and activity of retinal pigment epithelial cells,
which protect the eye from the harmful ultraviolet rays of the sun. This has a wide range of benefits from better
vision to disease protection.
The benefits of green tea for the eyes are many and different. You should not hesitate to enjoy all of them by
consuming it on a daily basis.
