Eye Health Supplements: What Actually Works and What to Avoid

When it comes to protecting your vision, eye health supplements, oral products designed to support vision and reduce age-related decline. Also known as vision support formulas, they’re marketed everywhere—from drugstore shelves to Instagram ads. But not all of them do what they claim. The truth is, only a few ingredients have real, reproducible science behind them. If you’re taking one just because it’s on sale, you might be wasting money—or worse, missing out on what actually works.

The two most proven nutrients for eye health are lutein, a carotenoid that filters harmful blue light and protects the macula. Also known as macular pigment, it’s found in leafy greens and is one of the few supplements shown in large human trials to slow macular degeneration. Pair that with zeaxanthin, a close cousin of lutein that works alongside it in the retina. Also known as retinal carotenoid, it’s critical for sharp central vision and is often combined with lutein in clinical studies. Together, they’re the backbone of most effective formulas. Then there’s omega-3 fatty acids, specifically DHA and EPA, which help reduce dry eye symptoms and support retinal function. Also known as fish oil for eyes, they’re not a cure-all, but people with chronic dry eyes often see real relief. Vitamin A? It’s essential for night vision, but unless you’re deficient—which is rare in developed countries—it won’t improve your eyesight. Most supplements pack too much of it, and too much vitamin A can be toxic.

What’s missing from most bottles? Zinc, copper, and antioxidants like vitamin C and E. These show up in the AREDS2 formula, the only eye supplement regimen backed by decades of NIH-funded research. It doesn’t restore vision, but it can slow progression in people with early to mid-stage macular degeneration. If you’re over 50 and have family history of vision loss, this combo matters. If you’re young and healthy? You probably don’t need a supplement at all—just eat more spinach, kale, salmon, and eggs. The real problem with eye health supplements isn’t that they don’t work—it’s that they’re sold like magic pills. The truth is, your eyes need consistent, long-term nutrition, not a quick fix.

Below, you’ll find clear, no-fluff comparisons of what’s actually in these products, who benefits most, and which ones are just expensive candy with vitamins. No hype. No sponsored posts. Just what the science says—and what you should skip.
