Synopsis

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

Fatty acid or fat/oil supplements, particularly those rich in omega-3 polyunsaturated fatty acids (such as EPA and DHA found in fish oil), have scientific validation for supporting eye health. The most notable evidence comes from large, well-conducted studies like the Age-Related Eye Disease Study 2 (AREDS2), which found that supplementation with omega-3 fatty acids may help reduce the risk of progression in age-related macular degeneration (AMD), one of the leading causes of vision loss in older adults. Omega-3 fatty acids are also essential structural components of retinal cell membranes and play a role in anti-inflammatory processes within the eye. Additionally, scientific reviews have shown omega-3 supplementation can benefit individuals with dry eye disease by improving tear film quality and reducing symptoms. While the evidence is not universally strong for all eye conditions, and not all studies have shown benefit, the overall consensus supports a moderate-to-strong scientific rationale for the use of fatty acid supplements in supporting eye health, particularly for AMD and dry eye syndrome. It’s important to note that these benefits are specific to certain types of fatty acids (mainly EPA and DHA) and not all fat/oil blends. Individuals should consult healthcare professionals before beginning supplementation, especially if they have underlying health conditions or are on medication.
