What to Look for in an Eye Vitamin: Vision+ Ingredients Explained

What to look for in an eye vitamin comes down to five things: lutein and zeaxanthin (the two carotenoids your retina stores), zinc paired with copper, the antioxidant vitamins C and E, a sensible amount of vitamin A, and a label that tells you what is inside. After that, look for proof of quality, such as third-party testing. This guide walks through each ingredient, what it does, and how Vision+™ is built, including the parts of its label that are a blend.

What to look for in an eye vitamin: the checklist

Ingredient	Why it is there	What to check
Lutein and zeaxanthin	Yellow pigments stored in the macula, the center of the retina	Both named; amounts shown or inside a blend
Zinc	Helps maintain normal vision and moves vitamin A to the retina	Paired with copper; total under 40 mg a day
Vitamin C	Antioxidant found in high levels in the eye's fluids	Amount and % Daily Value
Vitamin E	Fat-soluble antioxidant that protects cell membranes	Amount and form
Vitamin A	Needed for the light-sensing pigments in the retina	Modest amount; source (beta-carotene or retinol)

Lutein and zeaxanthin: the core of an eye formula

Lutein and zeaxanthin are the two carotenoids concentrated in the macula, and the body cannot make them. They come from leafy greens, egg yolks, corn and orange peppers, and in supplements they are usually extracted from marigold flowers. In the eye they act like internal sunglasses, filtering high-energy blue light and acting as antioxidants. Research measures them as "macular pigment," and studies of lutein and zeaxanthin supplements have looked at how they support that pigment and visual performance such as glare recovery. We explain the screen-time side of the research in Lutein and zeaxanthin for eye health and screen time.

Zinc and copper: why they belong together

Zinc supports normal vision, and a good formula pairs it with copper. Zinc is concentrated in the retina and helps carry vitamin A from the liver to the eye. But zinc taken for long periods can lower copper levels, so careful formulas include a small amount of copper as a balance. Count zinc from every supplement you take: the NIH Office of Dietary Supplements lists the adult upper limit as 40 mg a day from all sources, including food. Vision+ gives 32 mg per serving, so if your multivitamin also has zinc, add the two together, plus the zinc in your food.

Antioxidant vitamins C and E

Vitamins C and E are antioxidants that the eye uses in large amounts. Vitamin C is found at high levels in the fluid at the front of the eye, and vitamin E protects the fatty membranes of retinal cells. Both are easy to read on a label because they carry a % Daily Value.

A note on vitamin A and beta-carotene

Vitamin A is essential for seeing in low light. The NIH Office of Dietary Supplements says "several studies have shown that smokers, former smokers, and people exposed to asbestos who take high-dose beta-carotene supplements have a higher risk of lung cancer and death," which is one reason modern eye formulas lean on lutein and zeaxanthin instead. Add it up if you take more than one product: Vision+ gives 100 mcg RAE of vitamin A, all as beta-carotene. The NIH Office of Dietary Supplements lists the adult upper limit for preformed vitamin A (the form in retinyl acetate or retinyl palmitate supplements, liver, fish, dairy and eggs) as 3,000 mcg a day from food, beverages and supplements, and says "there are no upper limits for beta-carotene and other forms of provitamin A." So count the preformed vitamin A in your multivitamin and your food against that limit.

Red flags on an eye vitamin label

• Vague claims and no ingredient list you can read before buying.
• Very high zinc with no copper, which can upset the balance between the two over time.
• Large amounts of beta-carotene if you smoke or used to smoke.
• No mention of testing, or a "tested" claim that does not say by whom.
• Doubling up: a multivitamin plus an eye formula can push zinc and vitamin A higher than you expect.

How Vision+ is built

Vision+ is a daily eye-care formula that supports reading clarity and color perception, provides retina defense, and boosts the eye's own immune defenses.* Each two-capsule serving combines fourteen vitamins and minerals, each with its own amount on the label, with a 481 mg proprietary blend.

• Listed with amounts: vitamin A (as beta-carotene) 100 mcg RAE, vitamin C 200 mg, vitamin E 20 mg, niacin 40 mg NE, zinc 32 mg, copper 2 mg, plus thiamin, riboflavin, vitamin B12, biotin, calcium, magnesium, selenium and chromium. The niacin is above an upper limit on its own: the NIH Office of Dietary Supplements lists the adult upper limit for niacin from dietary supplements as 35 mg a day, and one serving of Vision+ gives 40 mg NE. If you also take a multivitamin or a B-complex, add up the niacin on every label, and talk with your healthcare provider before use.
• Inside the 481 mg blend: lutein, bilberry extract, alpha lipoic acid, eyebright, zeaxanthin, quercetin, rutin, L-taurine, grape seed extract and lycopene.

Here is the honest part: blend totals are on the label; the amounts inside each blend are not. That means the label tells you lutein and zeaxanthin are present, but not how many milligrams of each. The zinc in Vision+ is 32 mg per serving. The NIH Office of Dietary Supplements lists the adult upper limit as 40 mg a day from all sources, including food, so add up the zinc in your food and in any other supplement, such as a multivitamin, before you add another zinc product. The direction is two veggie capsules once a day, 20-30 minutes before a meal with an 8 fl oz glass of water; a bottle lasts 30 days.

The Vision+ label warning reads: "Do not exceed recommended dose. Pregnant or nursing mothers, children under the age of 18, and individuals with a known medical condition should consult a physician before using this or any dietary supplement. Keep out of reach of children. Do not use if safety seal is damaged or missing. Store in a cool, dry place." The National Center for Complementary and Integrative Health (NCCIH) says bilberry fruit extracts "have been used safely in research studies at doses of up to 160 mg/day for up to 6 months." Vision+ has bilberry extract inside its 481 mg blend, and the label does not list the bilberry amount. The sources below add medicine and smoking cautions for four Vision+ ingredients. The NIH Office of Dietary Supplements says zinc supplements "can interact or interfere with some medicines": quinolone antibiotics (such as Cipro) and tetracycline antibiotics "might reduce the amount of both zinc and the antibiotic that your body absorbs," so take the antibiotic "at least 2 hours before, or 4 to 6 hours after, taking a zinc supplement"; take zinc supplements and penicillamine "at least 1 hour apart"; and thiazide diuretics "increase the amount of zinc lost in urine." It also says orlistat (Alli, Xenical) "can decrease the absorption of vitamin A," and that acitretin (Soriatane) and bexarotene (Targretin) "are made from vitamin A," so taking them "together with a vitamin A supplement could cause dangerously high levels of vitamin A in the blood." It reports that in several studies, smokers, former smokers and people exposed to asbestos who took high-dose beta-carotene supplements had a higher risk of lung cancer and death; Vision+ gives its vitamin A (100 mcg RAE) as beta-carotene. For niacin, the NIH Office of Dietary Supplements says tuberculosis drugs (such as isoniazid and pyrazinamide) "interfere with the body's ability to convert tryptophan to niacin," which "can lower niacin levels in your body"; that high doses of nicotinic acid (1,500 mg/day or more) "can raise blood sugar levels and interfere with the effectiveness of diabetes medications"; and that experts do not recommend high doses of nicotinic acid for people taking a statin medication. Vision+ gives 40 mg NE of niacin. NCCIH says, "If you take any type of medicine, talk with your health care provider before using bilberry or other herbal products; some herbs and medicines interact in harmful ways."

If your eye doctor has recommended a specific formula for a specific need, follow that advice. The National Eye Institute's AREDS2 trial tested changes to the earlier AREDS formula (adding lutein and zeaxanthin or omega-3s, removing beta-carotene, lowering zinc) and enrolled only people with intermediate age-related macular degeneration (AMD) in both eyes, or in one eye with advanced AMD in the other. The resulting AREDS2 formula has 500 mg of vitamin C and 80 mg of zinc, per the National Eye Institute. Vision+ has lower amounts of both (200 mg and 32 mg), so if you have AMD, that is a conversation for your appointment.

Quality: the part you cannot see

Third-party testing is how you know the label matches the capsule. Every batch of Vision+ is tested for purity and potency by an outside lab and manufactured in USA with globally sourced materials in an NSF-certified, GMP-certified, FDA-registered facility. It is gluten-free, non-GMO, sugar-free, lactose-free and caffeine-free. Read how the testing works on our standards page.

Frequently asked questions about what to look for in an eye vitamin

Should an eye vitamin have lutein and zeaxanthin?

Most modern eye formulas include both, because they are the carotenoids the macula stores and the body cannot make them. Check that both are named on the label.

How much zinc is too much?

The NIH Office of Dietary Supplements lists the adult upper limit as 40 mg a day from all sources, including food and other supplements. Vision+ gives 32 mg per serving, so add up the zinc from your food and any other supplement before you add one. Long-term high zinc can lower copper, which is why eye formulas often add copper. The Vision+ label says not to exceed the recommended dose, and that pregnant or nursing mothers, children under the age of 18, and individuals with a known medical condition should consult a physician before using this or any dietary supplement. Vision+ also has bilberry extract in its blend; NCCIH says bilberry fruit extracts have been used safely in research studies at doses of up to 160 mg/day for up to 6 months, and the label does not list the bilberry amount. The NIH Office of Dietary Supplements also lists zinc interactions with some medicines: with quinolone or tetracycline antibiotics, take the antibiotic at least 2 hours before, or 4 to 6 hours after, a zinc supplement; take zinc and penicillamine at least 1 hour apart; and thiazide diuretics increase the zinc lost in urine. If you take any medicine, ask your healthcare provider before use.

Is bilberry good for your eyes?

Bilberry is a dark berry rich in anthocyanins, a family of antioxidants, and the National Center for Complementary and Integrative Health (NCCIH) says extracts of its fruit and leaves have traditionally been used for conditions related to vision, among other uses. NCCIH also says studies of bilberry and night vision have had conflicting results, much of that research was of poor quality, and the most rigorous studies have not found bilberry effective in improving night vision in healthy people. In Vision+, bilberry extract sits inside the 481 mg proprietary blend that supports retina defense.* The Vision+ label says not to exceed the recommended dose, and that pregnant or nursing mothers, children under the age of 18, and individuals with a known medical condition should consult a physician before using this or any dietary supplement. NCCIH also says bilberry fruit extracts have been used safely in research studies at doses of up to 160 mg/day for up to 6 months; the Vision+ label does not list the bilberry amount. NCCIH adds that anyone who takes any type of medicine should talk with a health care provider before using bilberry or other herbal products, because some herbs and medicines interact in harmful ways.

When is the best time to take an eye vitamin?

Lutein and zeaxanthin are fat-soluble, so a meal that contains some fat helps absorption. For Vision+, the label direction is two capsules once a day, 20-30 minutes before a meal, with water. Do not exceed the recommended dose, and if you are pregnant or nursing, under 18 or have a known medical condition, consult a physician before use. Vision+ has bilberry extract in its blend, and the National Center for Complementary and Integrative Health (NCCIH) says bilberry fruit extracts have been used safely in research studies at doses of up to 160 mg/day for up to 6 months; the label does not list the bilberry amount. If you take any medicine, check with your healthcare provider first: the NIH Office of Dietary Supplements says zinc, vitamin A and niacin supplements can interact with some medicines, and NCCIH says some herbs and medicines interact in harmful ways.

Can an eye vitamin replace an eye exam?

No. A supplement supports everyday eye health, but regular eye exams catch changes you cannot feel. Keep your scheduled checkups.
