Vision supplements (marketing category)
Marketing category for supplements sold as prevention of age-related vision changes, «computer vision syndrome» and «blue-light retinal protection». Includes carotenoids (lutein, zeaxanthin, astaxanthin), bilberry anthocyanosides, resveratrol, omega-3, zinc, vitamins A, C and E. According to USPSTF 2022 and Cochrane systematic reviews, in people without confirmed retinal pathology these supplements do not reduce the risk of age-related macular degeneration, cataract or diabetic retinopathy. AREDS2 (NEI 2013) showed a benefit of the antioxidant formula only in patients with intermediate or late AMD already present in at least one eye.
Also known as: Eye vitamins, Vision support, Eye health supplements, Carotenoids for eyes
Marketing claims without evidence base
The drug is promoted for these uses outside international guidelines. Each entry below is analyzed against AEMPS, FDA, EMA, Cochrane and major RCTs.
- DBilberry (Vaccinium myrtillus fruit extract)Not recommended · Herbal preparation, EMA HMPC traditional herbal medicinal productBilberry fruit extract is sold as an eye-health supplement and marketed for visual acuity, night vision, and eye fatigue. There is no convincing evidence that it helps for this use. When vision is a concern, an eye exam and treating the actual cause work: correcting refraction with glasses or lenses, managing dry eye, monitoring the retina in diabetes or age-related changes. Do not take bilberry in place of treatment with proven benefit, since that risks leaving a real condition untreated.
- DLuteinNot recommended · Xanthophyll carotenoid, supplement marketed for vision and skin supportLutein is a carotenoid that accumulates in the retina, and it's sold as a supplement for vision and eye health. Studies haven't shown a convincing benefit of taking lutein for this broad purpose – there's no solid evidence that the supplement improves eyesight or protects the eyes in healthy people. For specific eye conditions, an ophthalmologist decides on the diagnosis and treatment, and any supplement plan is worth discussing with them.
- DResveratrolNot recommended · Dietary supplements, plant polyphenols (local classification)Resveratrol is a polyphenol found in grapes and red wine, added to eye-health supplements and marketed as a way to protect the retina and support vision. Studies have not shown a convincing benefit for this use, and there is no solid evidence that it improves eyesight. For age-related retinal changes, what actually helps is different: regular check-ups with an ophthalmologist, control of blood pressure and blood sugar, and in some cases specific vitamin formulas with a proven composition chosen by a doctor. The substance itself is harmless in this role, but do not take it in place of prescribed treatment, since that risks missing care that genuinely works.
- DZeaxanthinNot recommended · Xanthophyll carotenoid, supplement marketed for retinal blue-light protectionZeaxanthin is a xanthophyll carotenoid that accumulates in the macula of the retina. It is marketed in "eye health" supplements for sharper vision, eye fatigue, and prevention in healthy people. No convincing benefit has been shown for zeaxanthin in this general use, and the "vision vitamins" category lacks an evidence base. Carotenoids have mainly been studied in people who already have age-related macular degeneration at specific stages, not for improving vision in general, so if your eyes bother you it makes more sense to discuss the cause with an ophthalmologist.
How to read tiers A–F
Evidence tiers belong to the drug-indication pair, not to the drug as a whole: the same substance can be A for one condition and F for another.
- AStrong evidence – first or second line in international guidelines
- BRecommended in selected cases
- CStudy data contradict each other
- DBenefit not proven, no documented harm
- FDocumented harm, or risk without benefit
