How We Choose

Most sunglasses roundups ask you to trust a claim you can’t check — “we tested 30 pairs” — with no test data attached. We take the opposite approach: we tell you exactly how a pick was made, from published specs you could look up yourself, so the reasoning is auditable. Here is the whole process.

The one thing we won’t pretend

We do not run a test lab, and we do not field-test the sunglasses we compare. The ranking field in this category leads with brands that own labs and buy dozens of pairs; we can’t honestly imitate that, and we won’t claim to. Pairs we claim to have field-tested: zero.We’d rather state that plainly than borrow authority we haven’t earned — and, as it turns out, the thing the whole field skips is the thing we’re good at: reading the specs honestly and explaining the lens science.

What we actually do instead

For every pick, we compile and compare the specs that decide a lens:

• UV protection— the non-negotiable. We confirm the lens is labeled UV400 or 100% UVA/UVB before it can be recommended at all. Our UV guide explains why this matters more than tint or price.
• Polarization— whether the lens is polarized, and whether that’s right for the use. It’s essential for fishing and driving, wrong for reading a golf green. See our polarized guide.
• Lens tint and material— what the tint does to contrast and color, and whether the lens is glass, polycarbonate or a brand blend. Our lens colors guide has the tint table.
• Frame fit and build— the shape (which we match to face shape and use), the material, and grip for sport. See the face-shape guide.
• Value— the price band against what you actually get. A cheaper pair that does the job wins, regardless of commission.

Where the data comes from

Product specs are read from the retailer and brand listings, and every product card links to the exact source with the date we read it. Where a brand does not publish a figure — a specific polarization state, an exact frame weight — we print “Not published” rather than inventing one. Eye-health and lens-science facts (UV, cataract risk, how polarization works) are cited to published authorities: the American Academy of Ophthalmology, the FDA, the World Health Organization, the CDC and Prevent Blindness. Every guide ends with a Sources list.

How prices work

We never type a price into an article. Every price on the site is pulled live from Amazon and stamped with the date it was checked. If a number is more than a couple of days old, it disappears on its own and the button falls back to “Check price on Amazon” — so you never see a stale figure. This also keeps us compliant with Amazon’s rules about displaying prices.

How we stay honest

• Balanced verdicts.Every pick lists real trade-offs and a “skip this if” — never all-positive.
• Commission never decides a ranking. The reasoning is identical whether a link earns us anything or not. See our affiliate disclosure and editorial policy.
• No fabricated reviews or ratings. There are no invented testimonials, star scores or before-and-afters anywhere on this site.
• Corrections welcome.Find a spec that doesn’t match the source? Tell usand we’ll fix it and say so.
