DHA (docosahexaenoic acid) is an omega-3 fatty acid that is a major structural component of the retina in the eye. Scientific evidence supports its role in ocular health, particularly in visual development and retinal function. Numerous studies demonstrate that DHA is essential for the normal development of vision in infants, as it constitutes up to 60% of the polyunsaturated fatty acids in the retina. Clinical trials have shown that maternal DHA supplementation during pregnancy and breastfeeding improves visual acuity in infants. In adults, observational studies indicate that higher dietary intake of DHA is associated with a reduced risk of age-related macular degeneration (AMD), although randomized controlled trials have produced mixed results regarding its efficacy in preventing or slowing AMD progression. Animal studies further confirm that DHA deficiency leads to impaired retinal function and visual deficits. While DHA is not a cure for eye diseases, its structural and functional role in retinal health is well established, and dietary recommendations for omega-3 fatty acids often highlight their importance for ocular health.
