Sourcing hierarchy
When sources conflict, we rank them in this order:
- The current product label, read directly from product imagery or a bottle
- The vendor’s own published terms — pricing, shipping, refunds
- Vendor marketing claims, labelled as such
- Regulatory and government sources (FDA, NIH, national eye institutes)
- Peer-reviewed human trials and systematic reviews
- Professional bodies (optometry and ophthalmology associations)
- News coverage and secondary reporting
Marketing claims rank low deliberately. Where a vendor claim cannot be verified against anything above it, we report the claim and state that it is unverified rather than presenting it as fact.
Evidence grading
We grade ingredients, not products. An ingredient can be “established” while the product containing it remains unproven, because ingredient research uses different doses, different routes and different populations. We label every grade as ingredient-level, and we never describe a finished product as clinically proven unless a trial of that finished product exists.
What we will not publish
- Star ratings or review counts we cannot verify
- Testimonials we have not collected ourselves, presented as representative
- Invented expert authors or medical reviewers
- Claims that a supplement treats, cures or prevents disease
- “FDA approved” as applied to a supplement
- Fabricated structured data, including aggregate ratings
- Urgency or scarcity devices that are not literally true
Fact-checking workflow
Every factual claim about the product is checked against the label transcription before publication. Dose figures, ingredient names, serving size, warnings, distributor details and prices are all verified against primary material. Claims about research are checked against the cited paper’s abstract and, where necessary, its methods.
An editor then reads the finished page for balance — specifically looking for sections that repeat marketing language without marking it as such, and for conclusions that the evidence in the page does not support.
Corrections
Errors are corrected, not quietly removed. Substantive corrections are noted at the foot of the page with the date. If you find an error, email editorial@eyefortin-reviews.com with the page and the correction.
Independence
No manufacturer, seller or agency has any input into what we publish. We do not accept payment for coverage, do not allow brands to review drafts, and do not publish sponsored content. Affiliate commissions are disclosed in the footer of every page and explained on the affiliate disclosure page.
Update cycle
Product pages are reviewed when the label, price or terms change, and at least every six months otherwise. Every page carries a last-updated date.
