I worked as an optician and all you have to do is look outside and look at a hot spot on a car or something shiny, and if it diminishes almost completely they’re polarized.

Got mine recently. Was scared if they weren't polarized. Your test proved me wrong! Kudos for the good work.

You can also use a second known polarized lens, from another pair of glasses for example, and you basically do the same thing. You look through both lenses, and then as you're looking through both of them, you turn one lens 90°. If both lenses are polarized, then they will be relatively transparent, and light will go through both of them when the polarization of both lenses are aligned in the same direction, but when the lens's polarization are 90° to each other, they will turn opaque and not let any light through.

Best video on shades ever!! I just bought cheap one yet doubting if it’s really polarized or not. And yes, I have real polarized pair. Thank you!

You said you need to use an LCD display and you used an AMOLED one...

How can anyone give a dislike! That is straightforward valuable info. I’d bet that the disljets will secretly use that technique though!

A much easier way is using a common calculator quartz screen, turn calculator on, press some random numbers and do the same, screens turns all black on polarized.

You can also look at tinted car windows. Not after market film tinting, but the kind that is built into the glass. When you look at the window through polarized glasses you will see diamond shapes.

if u have a LCD monitor, wear your sunglasses while looking at the screen, then tilt your head left and right. If the monitor darken, u have a polarized glasses.

thanks :)

Thanks for this post. You´re an angel. I plan on buying polarized. I wanted to make sure there is a check system

Re: how to tell if sunglasses are "polarized", there is another simple test: if you have one pair of polarized glasses, you can place a 2nd pair of lenses behind (so you are looking thru both lenses at the same time. If aligned on the same plane, turn the bottom ( ? lense) 45 degrees (either Ryan. Or lt.). If this blocks out ALL light thru the lenses, the questionable lenses are polarized. The reason being that polarized lenses block light in one direction. If light travels thru both lenses initially, turning one lenses. Perpendicular to the other will block all light telling you that both lenses are "polarized".

This video was great at explaining the difference of lenses. Thank you!

Wow, didn't know my 4 year old prescription oakley glasses were polarized untill now. thank you!

That’s true! I found the colors changing weird at first haha but I have the best vision with them on while driving on sunny days. 😎☀️

Before the advent of the smart phone...we did exactly this but instead of using a smart phone "lens" as the 2nd lens...we held up the questionable sunglasses up to another pair of ACTUAL polarized lenses. If they turn darker (or blackout) as you rotated....you knew the 'questionable' sunglasses now passed the test and are actually polarized. *(I realize most people know this...but there might be a 16 yr old or really young person who doesn't know this.)

Thanks for that explanation. Was remembering people complaining polarized making phones turn black and my coworker checking out my new prescription sunglasses and noticing they could see their phone screen when I mentioned they were polarized and started to worry the dealer didn't hear me say I wanted them polarized
