Synopsis

Source of validity: Scientific
Rating (out of 5): 4

Oranges, primarily known for their high vitamin C content, have scientific backing for their role in supporting eye health. Research has demonstrated that vitamin C is a potent antioxidant, and antioxidants are crucial for protecting the eyes from oxidative stress, which can contribute to cataract formation and age-related macular degeneration (AMD). A 2018 study published in the journal Ophthalmology found that higher intakes of vitamin C-rich foods, including oranges, were associated with a reduced risk of developing AMD. Additionally, oranges contain other phytonutrients such as flavonoids, carotenoids (like beta-cryptoxanthin and lutein), and vitamin A precursors, which are also known to benefit eye health.

While oranges are not a cure or direct treatment for eye diseases, regular consumption as part of a balanced diet rich in various fruits and vegetables may help maintain overall eye health and reduce risk factors for certain age-related eye conditions. However, the evidence is largely based on population studies and the known functions of vitamin C and other micronutrients, rather than randomized controlled trials focusing solely on orange consumption. Thus, while the scientific community recognizes oranges as supportive to eye health, they should be considered one component of a broader dietary approach to eye care.
