Synopsis

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

Eggs are a scientifically validated food for supporting eye health, primarily due to their high content of lutein and zeaxanthin—two carotenoids known for their role in maintaining eye function and reducing the risk of age-related macular degeneration (AMD) and cataracts. These carotenoids accumulate in the retina, where they help filter harmful blue light and act as antioxidants. Multiple studies have demonstrated that regular consumption of eggs increases serum levels of lutein and zeaxanthin. For example, a randomized controlled trial published in the American Journal of Clinical Nutrition (Goodrow et al., 2006) found that eating one egg daily for five weeks significantly increased both serum and macular pigment levels of these carotenoids. Additionally, eggs provide vitamin A, which is essential for normal vision and preventing night blindness. While other foods like leafy greens are also rich in lutein and zeaxanthin, eggs are particularly effective due to the high bioavailability of these nutrients when consumed with egg yolk fat. Overall, the use of eggs to support eye health is well-supported by current nutritional science, though they should be consumed as part of a balanced diet.
