iGenics and TheyaVue are two of the most-searched-together names in our Vision Supplements Guide, and both build their formulas around the carotenoids lutein and zeaxanthin, the same nutrients studied in the NIH’s AREDS2 trial on intermediate age-related macular degeneration. Neither product has been clinically tested itself, and neither is a substitute for an eye exam or treatment for a diagnosed eye condition. This is a direct, head-to-head look at what each one contains, what it costs, and which one fits your situation better.
Quick take: iGenics (6.0/10) rates higher than TheyaVue (5.5/10), mainly because iGenics discloses individual milligram doses for every ingredient on its Supplement Facts panel, while TheyaVue does not. Both are built around the same core carotenoids studied in AREDS2, but neither has a clinical trial on its own finished formula.

Which One Should You Choose?
Both products lean on the same AREDS2-associated carotenoids, so the real difference between them is transparency and guarantee length, not a difference in what problem each one claims to solve.
Pick iGenics if: you want to know the exact milligram amount of every ingredient you’re taking, and you value the longer 180-day guarantee.
Pick TheyaVue if: you specifically want a formula centered tightly on lutein and zeaxanthin and are comfortable without a disclosed per-ingredient dose.
Neither product has been tested in a clinical trial as a finished formula, and neither is a substitute for a comprehensive eye exam. If you have been diagnosed with macular degeneration, cataracts, glaucoma, or any other eye disease, see an ophthalmologist for treatment and ask them before adding any supplement.

FAQ
Is iGenics or TheyaVue better for macular degeneration?
Neither product is a treatment for macular degeneration or any other diagnosed eye disease, and neither has a clinical trial on its finished formula. Both include carotenoids studied in the AREDS2 formula, but that research was conducted on a specific clinical formulation, not on either of these commercial products. If you have been diagnosed with macular degeneration, see an ophthalmologist for treatment.
Can I take iGenics and TheyaVue together?
We don’t recommend combining two eye-health supplements without talking to a healthcare provider first, since both are built around similar ingredients and stacking them could mean exceeding a comfortable intake of certain nutrients like zinc or vitamin A without added benefit.
Which one has the better refund policy?
iGenics’ stated guarantee window is longer (180 days vs. TheyaVue’s 60 days), but always confirm the current guarantee terms on the official site before buying, since policies can change.
Do either of these replace a comprehensive eye exam?
No. Both are dietary supplements marketed for general eye health support, not a diagnosis or treatment tool. Regular comprehensive eye exams are the only way to detect and monitor conditions like macular degeneration, cataracts, or glaucoma.
