This answer focuses on strength of evidence and what the studies can or cannot prove. - Major vision-threatening conditions such as glaucoma, cataracts, age-related macular degeneration (AMD), diabetic retinopathy (DR), uveitis, retinal detachment, etc., contribute significantly to functional disability and reduced quality of life [,]. [De Silva Sandun (2026); evidence level 4] - Oxidative stress, chronic inflammation, mitochondrial dysfunction, dysregulated angiogenesis and metabolic imbalance are highly associated with the molecular-level pathogenesis of these ocular diseases. [De Silva Sandun (2026); evidence level 4] - Furthermore, bioavailability and therapeutic potential are increased by synergistic interactions among bioactives in whole extracts and improvements in delivery systems (e.g., nano-formulations). [De Silva Sandun (2026); evidence level 4] - 1 2 2 3 4 5 6 Visual impairment is a major global health problem with an increasing prevalence due to population ageing, higher incidence of metabolic diseases such as diabetes, and prolonged exposure to digital devices. [De Silva Sandun (2026); evidence level 4] - 1 2 3 5 6 7 8 9 More than two billion people are at risk of micronutrient deficiencies, which often involve multiple, rather than single, nutrients [,]. [Muacevic Alexander (2026); evidence level 4] Evidence levels are sorting aids, not final clinical grades. Level 1 usually indicates systematic-review style evidence, level 2 indicates randomized trials or public-health guidance, and lower levels need more cautious wording. This page is educational.
