How We Choose

Most sunglasses roundups lead with “we tested” and hope you don’t ask how. We take the opposite approach: we state plainly that we have not physically handled every frame we compare, and we compete on a method that doesn’t need a test lab — reading each frame against its published specs and the fit math, transparently and reproducibly. Follow our steps with the same listings and the same research and you should reach the same conclusions.

1. We start from the spec, not the marketing

Every frame is evaluated on what its listing and the brand actually state: the frame material(cellulose acetate, bio-acetate, or honestly noted when it’s polycarbonate), the frame shape, the lens protection (UV400, 100% UV), whether it’s polarized, and any published measurements. Each fact is read from the listing on a dated visit, and that date is shown on the page. Where a seller doesn’t publish a figure — often the case for exact frame widths — we print “Not published.” That empty cell is a finding, not a gap in our research.

2. We do the fit math

A recommendation should be reasoned, not asserted. We map a frame’s shape and width to the face shapes it flatters using the same contrast rules our face-shape guidesexplain — angular frames for round faces, round frames for square faces, and so on. When we say a frame suits a heart-shaped face, there’s a reason behind it you can check, not just an opinion.

3. Every protective claim is cited

When we say UV400 blocks UV up to 400 nanometers, or that polarization isn’t the same as UV protection, that claim links to a published source — the FDA, the American Academy of Ophthalmology, the WHO, or the ISO sunglasses standard. We don’t assert eye-health facts on our own authority, because we haven’t earned that authority; we point you to the people who have.

4. Rankings are argued, not scored

You will not find a numeric “9.2/10” anywhere on this site. A score implies a controlled measurement, and we haven’t measured these frames in a test — slapping a number on a spec sheet would dress reading up as testing. Instead, our rankings are reasoned in plain language: which frame suits which face, why one wins for a first serious pair and another for a budget, and where the buyer-first choice is the cheaper option. That means an occasional “skip this” — which is the point.

5. Prices are live and dated — or they disappear

Every price on the site is pulled from a live retailer feed and stamped with the date it was pulled. We don’t store prices in our content, so a stale number can’t sneak onto a page. If the daily price check stops running, the numbers expire on their own within 48 hours and the buttons fall back to “Check price on Amazon” — the failure mode is silence, never a wrong figure.

6. We never fabricate proof

There are no invented reviews, testimonials, star ratings, or before-and-after photos anywhere on Acetate Club. Product images come from the retailer. Verdicts are ours, written from the published specs. If we can’t source something honestly, it doesn’t appear.

7. Commission never decides a recommendation

We earn affiliate commissions, and we disclose them everywhere they apply. But the reasoning behind a pick is identical whether a link earns us anything or not. When a cheaper frame is the better buy, it’s our pick, even though the pricier one would pay us more. Read the full affiliate disclosure and our editorial policyfor how that’s kept honest.

Where we could be wrong

Reading specs is not the same as handling every frame, and we don’t claim it is. Listings can be inaccurate, models get changed, and a stated measurement isn’t the only thing that decides how a frame fits a specific face. Treat our guidance as well-researched starting points, not verdicts from a lab — and nothing here is professional eye-care advice. If you find an error, tell usand we’ll correct it in the open.
