Tomatoes for Eye Health

Research suggests that tomatoes and their constituent carotenoids, particularly lycopene and beta-carotene, may support eye health through antioxidant activity and associations with reduced risk of eye-related disorders, based on a 2024 narrative review of the broader scientific literature on these compounds. A separate 2022 bioengineering study demonstrated that tomatoes can be genetically engineered to produce lutein and zeaxanthin, two carotenoids with established relevance to eye health that are not naturally present in meaningful quantities in conventional tomatoes, suggesting potential future directions for nutritionally enhanced crops. The available evidence consists of a review article and an experimental laboratory study rather than clinical trials or human intervention studies, which limits the strength of conclusions that can be drawn about tomatoes directly improving eye health outcomes in people. Studies indicate this is an area of ongoing scientific interest, but readers should be aware that the current evidence base does not yet include the kinds of controlled human trials that would be needed to confirm specific benefits.
