How Green Tea Protects Your Eyes

Posted on | May 7, 2011 | No Comments

For thousands of years, green tea has been enjoyed for its soothing taste and healing properties, but until recently many of its disease-fighting mechanisms were not well understood.


Although it was known that green tea contained antioxidants that likely played a role with regard to improving health and having an anti-cancer effect on many body systems, no scientific studies in the past had specifically demonstrated how green tea might be beneficial to the eyes.


But starting in 2002, research conducted at various medical institutes and colleges began to reveal the numerous ways that the constituents in green tea appear to protect vision.


At the All Indian Institute of Medical Sciences, one research study on how green tea can influence visual health revealed that the plant possessed properties that strengthened the body’s antioxidant defense system and inhibited the development of cataracts.


Later in 2007, researchers at the Chosun University College of Medicine discovered that the antioxidant EGCG present in green tea penetrated the lens, retina, and other tissues of the eye, and increased cellular activity, which helps combat oxidative stress.


As a result of the study, EGCG absorption was determined to preserve and enhance vision in multiple ways, including protecting the retina of the eye against ultraviolet (UV) damage, the lens, and aqueous humor, and preventing age-related macular degeneration, glaucoma, cataracts, and other common afflictions of the eye.


Reinforcing these findings, another recent animal study published in the Journal of Agriculture and Food Chemistry examined the effects of additional catechin components found in green tea such as gallocatechin, vitamin E, vitamin C, lutein, and zeaxanthin.


Substantial amounts of these potent nutrients were also found to be absorbed by all of the eye tissues, most prominently in the retina, and were shown to reduce the harmful effects of oxidative stress for up to 20 hours after consuming green tea extract.


Thus drinking green tea with its many health-promoting ingredients appears to offer a simple, natural, and effective means to nourish the eyes and guard against the development of vision problems resulting from oxidative damage over time with age that plague many people today and seriously disrupt their lives by preventing them from driving, cooking, reading, and performing other normal daily activities.


Taking advantage of green tea’s proven protective properties by consuming a cup or two a day as a preventative measure might be a wise choice if you want to help support optimal eye health and improve future function, quality of life, and well-being.
