This narrative review critically summarizes the available evidence on how various natural bioactive compounds, such as carotenoids, polyphenols, flavonoids, omega-3 fatty acids and botanical extracts, can affect important molecular pathways associated with ocular degeneration. Their antioxidant, anti-inflammatory, anti-angiogenic and neuroprotective properties are given particular emphasis, especially regarding the Nrf2, NF-\u03baB and VEGF signaling pathways. This review is different from past reviews that simply discuss the potential of bioactives in the general nutritional context; rather, it unfolds the disease-specific mechanisms and compound-specific molecular actions and gives special attention to recent advances in nano-delivery systems and precision nutrition strategies to increase the bioavailability and therapeutic targeting of these nutrients in the eyes. Moreover, it offers a framework for a comparison of evidence between preclinical and clinical studies, as well as identifying current translational gaps, including limited bioavailability and a lack of long-term clinical trials, and suggesting future directions such as genotype-guided nutrition and microbiome-informed interventions. In general, this review provides a mechanistic and translational overview of how dietary bioactive compounds relate to eye health and offers the perspective of their possible use in prevention and complementary treatment for vision-related diseases.<\/jats:p>","DOI":"10.3390\/ijms27104592","type":"journal-article","created":{"date-parts":[[2026,5,20]],"date-time":"2026-05-20T14:12:54Z","timestamp":1779286374000},"page":"4592","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Beneficial Effects of Natural Bioactive Compounds on Eye Health: A Narrative Review"],"prefix":"10.3390","volume":"27","author":[{"ORCID":"https:\/\/orcid.org\/0009-0001-7996-2362","authenticated-orcid":false,"given":"Sandun","family":"De Silva","sequence":"first","affiliation":[{"name":"Food Science and Technology Program, Department of Life Sciences, Beijing Normal-Hong Kong Baptist University, Zhuhai 519087, China"},{"name":"Department of Food Science and Technology, Faculty of Agriculture, University of Ruhuna, Mapalana, Kamburupitiya 81100, Sri Lanka"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0739-3735","authenticated-orcid":false,"given":"Baojun","family":"Xu","sequence":"additional","affiliation":[{"name":"Food Science and Technology Program, Department of Life Sciences, Beijing Normal-Hong Kong Baptist University, Zhuhai 519087, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2026,5,20]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"D\u2019Angelo, A., Giannaccare, G., Lixi, F., Troisi, M., Adamo, G., Lee, D., De Pascale, I., Pellegrino, A., and Vitiello, L.
