TheyaVue Guides and Free Reading

Two long guides, three posts from the editorial desk, and a six-step method for reading any supplement label with the bottle in your hand.

Written and reviewed by the TheyaVue Editorial Desk · Last updated September 23, 2026

Quick answer

Five pieces of free reading about eye and vision supplements, none of it about buying anything. Two long guides cover what the category is and how to choose within it; three shorter posts cover what AREDS2 actually found, what a proprietary blend hides, and how a sales page can claim more than the label it sells. The fact underneath all of them: NEI reports that the AREDS supplements do not prevent AMD onset.

The short version

What is in this section

Five pieces of free reading, and not one of them is about buying anything. Two are long guides to the eye supplement category; three are shorter posts about specific ways a supplement label can mislead a careful reader — and this product demonstrates all three. They exist because the most useful thing a site like this can hand you is the set of checks that lets you form your own opinion about the next bottle, on a shelf where we have no interest at all.

Framing

What this category actually is, and why the panel decides it

The regulation, the one trial everybody cites, and the two sentences from that trial the marketing leaves out.

“Eye supplement” is a marketing category rather than a regulated one. Nothing about the phrase tells you what is in the bottle. Walk the shelf and you will find carotenoids, berry extracts, herbs named after the organ they are sold for, amino acids and B vitamins, all under the same four or five words. The ingredients vary enormously. The front-of-bottle vocabulary barely varies at all.

That matters because of how these products are regulated. A dietary supplement is not approved by the FDA before it is sold. The seller may make a structure/function claim — A structure/function claim may “describe the role of a nutrient or dietary ingredient intended to affect the normal structure or function of the human body, for example, ‘calcium builds strong bones.’” What the seller may not do is make a disease claim. A disease claim says a product can “diagnose, treat, cure or prevent any disease”. Only drugs may legally make one. And the agency is explicit about what does not happen first: These claims “are not pre-approved by FDA, but the manufacturer must have substantiation that the claim is truthful and not misleading and must submit a notification with the text of the claim to FDA no later than 30 days after marketing.” You never see the substantiation.

What AREDS2 actually found, and in whom

Two ingredients here do have a specific federal evidence base with published numbers attached: lutein and zeaxanthin, tested by the National Eye Institute in the Age-Related Eye Disease Studies. The AREDS2 formula was Vitamin C 500 mg, Vitamin E 400 IU, Copper (cupric oxide) 2 mg, Lutein 10 mg, Zeaxanthin 2 mg, Zinc 80 mg — the numbers any eye supplement can be measured against, when it publishes enough of its own to be measured.

Now the part the marketing almost never carries. AREDS2 ran in people who already had intermediate or advanced age-related macular degeneration, and it was about slowing progression in that group. NEI’s summary of both trials is two sentences: “AREDS and AREDS2 supplements do not prevent AMD onset.” and “None of the formulations decreased cataract risk.” A healthy-eyed buyer taking an eye supplement because of a trial they half remember is taking it for a result that trial did not produce in people like them. A third finding belongs on the front of every bottle in the category and is on almost none: AREDS2 removed beta-carotene. NEI: “Current and former smokers should take the AREDS2 formula and avoid the AREDS formula with beta-carotene, which increases lung cancer risk.” This label’s vitamin A is beta-carotene.

Why reading the panel is the only defence a buyer has

Given all that, the Supplement Facts panel is not one source among several. It is the only document in the transaction the seller is accountable for and that you can hold before you swallow anything. The front of the bottle is an advertisement, seals included; the page it is sold from is another one, written to different rules and not required to agree with the label at all. The panel is the part with rules attached, and a panel that publishes its amounts can be checked in a way marketing cannot. This one does it fifteen times, which lets anybody see vitamin C at 200 mg against AREDS2’s 500 and zinc at 32 mg against 80. Then it stops: lutein and zeaxanthin sit inside 240.5 mg shared eight ways further. A blend total hides exactly the figure you came for.

Start here

The two long guides

One explains the category. The other turns it into an eight-step check you can run on any bottle on the shelf.

The Eye Supplement Guide

A plain guide to eye and vision supplements: the ingredients that keep appearing, what the AREDS trials found and in whom, and what no label may claim. It covers what the phrase means on a label, which ingredients keep recurring across the shelf and why, and what the National Eye Institute has actually reported about the supplements sold for vision. Start here if the vocabulary is new. Read the guide →

Choosing an Eye Supplement

Eight checks to run on any eye supplement before you buy, including the three TheyaVue passes better than most and the three it does not pass at all. Eight checks, in order, with what a pass and a fail look like on each. Does the panel publish an amount for every ingredient, or hide the important ones in a blend? Do the directions and the servings count agree? It runs all eight on this product. Run the eight checks →

Read them in that order. The first gives you the vocabulary, so that words like blend, extract, standardised and carotenoid stop being decoration and start being things with definitions. The second turns it into a sequence you can run with a bottle in your hand, in a shop, without looking anything up.

The blog

Three posts from the editorial desk

Shorter pieces, each built around one label problem and one worked example.

What The AREDS2 Trial Actually Found

The most-cited trial in eye supplements is also the most misquoted. Here is what it tested, in whom, and the two sentences buyers almost never see. Read the post →

When A Blend Hides The One Number That Matters

A proprietary blend is legal, common and usually harmless. On an eye supplement it hides the single figure the whole category is judged on. Read the post →

When The Page Claims More Than The Bottle

A supplement label and the page that sells it are written to different rules. Here is how to tell which one is binding, in about thirty seconds. Read the post →

Each takes one thing that goes wrong on supplement labels generally and works it through on a real example. The first reads AREDS2 end to end: what it tested, in whom, and the two sentences about prevention and cataracts that rarely reach an advertisement. The second is about the choice between printing your amounts and hiding them behind a blend total — the choice this label made fifteen times one way and once the other. The third is about the gap between a regulated label and the unregulated page that sells it. All three are on the editorial desk blog.

The method

How to read any supplement label in five minutes

Six steps, no expertise and no equipment. Steps two, three and five are the ones that find things.

  1. Turn the bottle round and find the Supplement Facts panel

    Everything on the front is advertising, seals included. The panel is where the statements with rules attached to them live.

  2. Check whether every ingredient has its own amount

    A published amount can be checked against research. A blend total cannot. If one number covers ten ingredients you cannot tell whether the headline ingredient is most of it or a dusting — only that it is listed first, because members run in descending order by weight.

  3. Read the serving size against the directions

    Four seconds, and almost nobody runs it. If the panel’s serving size and the directions disagree, the percentages and the advertised supply both describe something other than what you will do. Here the panel says one capsule and sixty servings while the directions say two a day.

  4. Read the marketing list against the panel list, name by name

    Every name in the advertising should appear on the panel, and the interesting gap usually runs the other way. Here the panel names twenty-five and the marketing names six.

  5. Set each published amount against the amount the research used

    AREDS2 used vitamin C 500 mg, vitamin E 400 IU, zinc 80 mg, copper 2 mg, lutein 10 mg and zeaxanthin 2 mg. Compare what you can, and note which rows you cannot compare — those are the ones the label chose not to let you check.

  6. Read the other-ingredients line, then check every seal against it

    That line declares the capsule shell and the fillers, and it is where a vegetarian claim stands or falls. Here it reads “Cellulose (Vegetable Capsule), Rice Flour, Magnesium Stearate, Silicon Dioxide”, so the vegetarian roundel is supported by the label’s own words — a pass, and worth saying as loudly as the failures.

What this product does with those six steps

It passes steps one and six outright. It fails step two in the one place an eye buyer cares about, because lutein and zeaxanthin are inside the blend. It fails step three, because the panel and the directions describe different products, and step four by nineteen ingredients. Step five gives one exact match, copper, and three rows below the trial. Several different outcomes from one label, which is why a single star rating is such a poor way to describe a bottle.

The honest section

Where this reading stops

A last word on where this stops. The federal pages cited here are consumer summaries of individual ingredients. Not one studied this formula. NCCIH on the classic vision botanical in this bottle shows how thin the ground is: “Studies of the effects of bilberry on night vision have had conflicting results. Much of the research was of poor quality.” and “Bilberry has not been clearly shown to be helpful for any health condition.”

These guides give you a method and a vocabulary, not an answer about your own eyes. NEI: “A dilated eye exam is the only way to check for many eye diseases early on, when they’re easier to treat.” And the FDA, on unapproved eye products: they “Unapproved drugs claiming to cure serious conditions may lead consumers to delay or abandon proven, safe treatments.”

Three things NEI recommends cost nothing. On diet: “Be sure to have plenty of dark, leafy greens like spinach, kale, and collard greens. Eating fish that are high in omega-3 fatty acids - like salmon, tuna, and halibut - is good for your eyes, too.” On sunlight: “Protect your eyes from the sun by wearing sunglasses - even on cloudy days! Be sure to look for sunglasses that block 99 to 100 percent of both UVA and UVB radiation.” On screens: “Rest your eyes by taking a break every 20 minutes to look at something about 20 feet away for 20 seconds.”

Questions

TheyaVue FAQ: guides questions

How does it compare to the AREDS2 formula?

Four ingredients overlap. At the directed two capsules a day: copper matches at 2 mg, vitamin C is 200 mg against 500, vitamin E is 20 mg against 400 IU, zinc is 32 mg against 80. Lutein and zeaxanthin cannot be compared at all.

Will TheyaVue improve my eyesight?

Nothing we were given supports that. The label claims support, not improvement, and no trial of this formula has been published. The National Eye Institute’s AREDS2 trial — the closest real evidence in this category — slowed progression in people who already had intermediate or advanced macular degeneration, and NEI states the supplements “do not prevent AMD onset”.

Does it help with cataracts?

NEI’s finding across all the AREDS formulations is one sentence: “None of the formulations decreased cataract risk.” Cataracts are a diagnosis and a surgical question, not a supplement question.

Does it help with night vision?

Bilberry is the ingredient that claim usually rests on. NCCIH: “Studies of the effects of bilberry on night vision have had conflicting results. Much of the research was of poor quality.” More broadly, “Bilberry has not been clearly shown to be helpful for any health condition.”

How much lutein is in it?

Not published. Lutein is the first-named member of the 240.5 mg proprietary blend, and a blend may declare one total on condition its members run in descending order by weight. So lutein is the largest of ten shares of 240.5 mg — and that is everything the label tells you. AREDS2 used 10 mg.

Should I use this instead of an eye exam?

No, and this is the answer on this page we would ask you not to skim. NEI: “A dilated eye exam is the only way to check for many eye diseases early on, when they’re easier to treat.” The FDA adds that unapproved products claiming to treat eye conditions “may lead consumers to delay or abandon proven, safe treatments”.
