Synopsis
Source of validity: Scientific
Rating (out of 5): 3
Tea, particularly green and black tea, has been studied for its potential benefits to eye health, primarily due to its rich content of polyphenols such as catechins, flavonoids, and other antioxidants. Scientific research indicates that these compounds can help protect the eyes from oxidative stress, which is a contributing factor in the development of cataracts, age-related macular degeneration (AMD), and other eye diseases. For example, animal studies have demonstrated that catechins from green tea can be absorbed by various eye tissues, including the retina, and may reduce oxidative damage. Epidemiological studies in humans suggest an association between regular tea consumption and a reduced risk of certain eye conditions, although the evidence is not definitive and more clinical research is needed.
Additionally, the anti-inflammatory properties of tea polyphenols may provide some protection against diabetic retinopathy and glaucoma. However, while laboratory and animal studies are promising, large-scale, high-quality clinical trials in humans are limited. Therefore, the use of tea (mixed) to support the eyes is best described as having moderate scientific support, especially as an adjunct to other healthy lifestyle practices. Traditional use also exists, but the scientific evidence is more prominent in justifying its role for eye health.
