Ordered Ralph Lauren "polarized" sunglasses but weren't actually polarized.

Well, I am selling Ralph Lauren too (also this specific model). To date I have had quite some Ralph Lauren sunglasses in my hands, but none of them were polarized indeed.

So, can you help the OP?

It's all Luxottica's fault.

My favorite way to test is with another pair of polarized glasses.

A polarization test is very simple - find yourself any LCD screen, like the computer screen you're looking at right now. Hold the glasses (or lenses, if not mounted) in front of you so you can see the screen through them. Start rotating them clockwise / counter-clockwise. If they're polarized, at some point the screen through the lenses will darken and then block out completely. If there's no change, not polarized.

LCD screens are polarized already. When you do this test, you're lining up the orientation of your polarization with the polarized image coming from the screen, blocking it out. This is why sometimes you can't see LCDs when wearing polar glasses - the default polar orientation of those LCDs matches what it blocked by your shades...

BTW if you do that test and each lens blocks the LCD at different times / angles, then that means your lenses don't have matching polarization orientation, which is not good. That shouldn't happen with Oaks, unless it's a clumsy custom cut job.

Technically they're aligned 90 degrees out of phase.

And there's also the all-too-fun circular polarizing filters.

So I'm not sure what to do at this point. She wants the style (she had the style before until they got lost) but she's upset they're not polarized.

You take an awesome pair of polarized Oakleys (easy to find because they're all awesome) and wear them. Then you hold the other glasses up to the sun as if you were putting them on your face. You turn them 90 degrees each way. You should see a significant decrease in transparency, to the point that it's completely blacked out.
