PreserVision is an eye health supplement built around the AREDS 2 formula, a specific combination of vitamins, minerals, and plant-based pigments tested in large clinical trials funded by the National Institutes of Health. The daily dose (two soft gel capsules) contains six active ingredients: 500 mg of vitamin C, 180 mg of vitamin E, 80 mg of zinc, 2 mg of copper, 10 mg of lutein, and 2 mg of zeaxanthin. Each ingredient is included at a precise amount matched to the formula shown to reduce the risk of advancing to late-stage age-related macular degeneration (AMD) by about 25%.
The Six Active Ingredients
The formula breaks down into three categories: antioxidant vitamins, minerals, and carotenoids. Vitamin C (500 mg) and vitamin E (180 mg) are high-dose antioxidants that help neutralize damage from unstable molecules in the eye. These doses are significantly higher than what you’d get from a standard multivitamin.
Zinc is included at 80 mg, which is the most notable mineral in the formula. That’s a large dose, roughly five to eight times the typical daily recommendation. Because high zinc intake can block copper absorption over time and lead to a deficiency, the formula adds 2 mg of copper (as cupric oxide) specifically to offset that effect. The copper isn’t there for your eyes directly; it’s a safety measure for the zinc.
Lutein (10 mg) and zeaxanthin (2 mg) are yellow-orange pigments sourced from marigold extract. These two compounds naturally accumulate in the macula, the part of the retina responsible for sharp central vision. They serve a dual role there: absorbing high-energy blue light before it can damage retinal cells, and neutralizing reactive oxygen species that build up from normal light exposure over a lifetime. Think of them as both a built-in filter and a cleanup crew for the center of your vision.
Why Beta-Carotene Was Removed
If you’ve seen older bottles of PreserVision or heard about the original AREDS formula, the biggest change in the AREDS 2 version is the removal of beta-carotene. The original formula included it, but the clinical trial found that beta-carotene increased the risk of lung cancer in people who smoke or formerly smoked. The AREDS 2 study replaced beta-carotene with lutein and zeaxanthin, which showed possible benefits over beta-carotene without the cancer risk. That swap made the updated formula safe for smokers and became the new standard recommendation.
Inactive Ingredients and Allergens
Beyond the six active ingredients, the capsules contain several inactive components that hold the soft gel together. These include bovine gelatin (making it unsuitable for vegetarians), glycerin, medium-chain triglycerides (a type of fat that helps the body absorb the fat-soluble vitamins), purified water, titanium dioxide (a white colorant), and carmine (a red pigment derived from insects). The product is free of gluten, soy, lactose, dairy, preservatives, and artificial flavors.
Who the Formula Is Designed For
PreserVision isn’t a general eye vitamin or a prevention tool for people with healthy eyes. The AREDS 2 formula was tested specifically on people with intermediate AMD or those who already had advanced AMD in one eye. In that group, taking the supplement reduced the chance of the disease progressing to its most severe form by 25 to 30% over a ten-year follow-up period. For people without AMD, or those with only early-stage disease, the clinical trials didn’t show a meaningful benefit from taking the formula.
This is an important distinction because the high zinc dose in particular isn’t something most people need. The supplement targets a specific window of disease progression where the nutrient combination has been proven to slow things down.
How to Take It
The standard dosing is one soft gel capsule in the morning and one in the evening, both taken with meals. Splitting the dose across two meals rather than taking both at once helps your body absorb the fat-soluble components (vitamin E, lutein, and zeaxanthin) more effectively. The fat in your meal further aids that absorption, so taking it on an empty stomach isn’t ideal.
PreserVision also sells variations that add ingredients like CoQ10 or come in chewable form, but the core AREDS 2 ingredients and their doses remain the same across the line. If you’re comparing store-brand alternatives, matching those six ingredients at the exact amounts listed above is what matters. A study reviewing over-the-counter supplements found that many products marketed as “AREDS 2” don’t actually match the formula’s precise dosing, so checking the supplement facts panel against the standard amounts is worth the extra minute.
