Synopsis

Source of validity: Scientific
Rating (out of 5): 2

Green tea (Camellia sinensis) contains a variety of bioactive compounds, most notably polyphenols such as epigallocatechin gallate (EGCG), which have antioxidant and anti-inflammatory effects. There is emerging scientific evidence that these compounds may have a protective role in eye health. Several animal studies have demonstrated that green tea catechins can be absorbed by various tissues in the eye, including the retina, lens, and aqueous humor, where they exert antioxidative effects. For example, a 2010 study in mice published in the journal Journal of Agricultural and Food Chemistry reported that green tea catechins distributed to eye tissues after ingestion, reducing oxidative stress and potentially protecting against degenerative eye diseases like glaucoma and cataracts. Some small human studies and epidemiological data suggest that regular consumption of green tea may reduce the risk of certain eye conditions, such as age-related macular degeneration and diabetic retinopathy, likely due to its antioxidant properties. However, direct clinical evidence in humans remains limited, and no major ophthalmological guidelines currently recommend green tea as a primary treatment for eye problems. Most uses are as supportive measures rather than primary therapies. In summary, while there is promising preclinical evidence and a plausible scientific rationale for green tea supporting eye health, robust clinical trials in humans are lacking, so the evidence is rated moderate (2 out of 5) at present.
