The eyes, as highly metabolically active organs, depend on a steady supply of key nutrients to maintain optimal function and prevent degenerative conditions. This review highlights the critical role of diet in vision health, emphasizing essential nutrients such as vitamin A for night vision, omega-3 fatty acids for tear production, and lutein/zeaxanthin for macular protection. Dietary sources like egg yolks, zinc-rich foods (red meat, legumes, nuts), and antioxidant-rich fruits and vegetables contribute to ocular defence mechanisms against oxidative stress and age-related damage. Evidence-based findings underscore the importance of targeted nutrition in preserving visual acuity and reducing the risk of disorders like dry eye syndrome, cataracts, and macular degeneration.
