What is false polarization in sunglasses
How to tell if sunglasses are polarized in 3 SECONDS!
hey guys is iheart shades and today
we're gonna show you how to tell if a
lens is polarized or not um let's say
you find a lens and it's not clearly um
labeled as polarized or not you're not
sure you need a couple things you're
going to need an LCD screen your phone
your TV computer screen anything that
has actual pixels in it and you're going
to need of course your polarized lens um
let me show you with these today we're
gonna be using the the twenty one thirty
two new Wayfarers a sixty fifty twos
which is here on the left and the sixty
fifty two five eight which is the
polarized is here on the right um yeah
let's get to it here I'm going to use my
phone as the LCD now we're going to
start with the polarized so I'll show
you what it does and what it doesn't do
okay you know I got a text message see
this is why you can't use phone so flu
things like this one second guys alright
here we go here's a picture of of course
a Ray Ban picture so what you want to do
is when you want to grab the lens and
put it over the image and you want to
make sure you can see straight through
it and you want to rotate it now look at
the image how it changes colors see
right there it's really light and when I
rotate it back it gets darker and
there's going to be a point where it's
going to be darker than the rest because
these are polarized at an angle so about
here is the darkest point and that's how
you tell they're polarized now let me
show you what happens when I use the
normal standard ones put it over and you
rotate it and it does absolutely nothing
let's try it again polarized so you guys
have a you can see the colors changing
and refracting and doing all these
things thank you guys for watching

is pretty straightforward
