Synopsis

Source of validity: Scientific
Rating (out of 5): 3

Tomato (Solanum lycopersicum) is scientifically recognized for its potential benefits to eye health, primarily due to its high content of carotenoids, especially lycopene, lutein, and beta-carotene. These compounds are antioxidants, which help protect ocular tissues from oxidative stress and damage caused by free radicals. Lutein and zeaxanthin, in particular, are concentrated in the macula of the eye and are known to filter harmful high-energy blue wavelengths of light and help protect and maintain healthy cells in the eyes. Several epidemiological studies suggest that diets rich in these carotenoids are associated with a lower risk of age-related macular degeneration (AMD) and cataracts.

Tomatoes are a good dietary source of these nutrients, though they are not the richest source compared to some leafy green vegetables. Lycopene, the pigment that gives tomatoes their red color, has also been studied for its role in preventing oxidative damage in the eyes. Some clinical studies suggest that higher serum lycopene levels are linked to a reduced risk of certain eye diseases, though evidence is not as strong or direct as for lutein and zeaxanthin.

Overall, while there is scientific rationale and some supporting evidence for the use of tomato in supporting eye health, particularly through its carotenoid content, the evidence is moderate rather than conclusive, and tomatoes are best considered as part of a balanced, carotenoid-rich diet for eye support.
