We're so sorry for any inconvenience!
When you order polarized lenses, it can be possible to receive a non-polarized pair. However, before emailing us, there is a simple test to try just to make sure that is the case. There are two ways to perform this test:
All you will need for this one is a back-lit LCD computer. With your lenses installed, look at the computer screen through your lenses, then, start to rotate your glasses. If your lenses are polarized, it will start to get darker as you turn it until it blacks out. The reason why this test works is because LCD screens also use polarized technology.
Pop Out Your Lenses
If you just recieved your lenses, this test is great to try since it requires your lenses being out of the frame.
The first thing you should do is find a sheet of white paper. With both of your lenses already popped out of your frames, hold one lens on top of the white paper as if you were looking through it. Hold the other lens on top of the first facing the same direction and slowly start turning it until the second lens is vertical to the first one. If it is polarized, you should see the overlap area of the two lenses progressively getting darker until it completely blacks out.
This is because the bottom lens blocks out horizontal light waves and the top lens blocks out vertical light waves. The bottom and the top lenses cancel each other out which means no light can pass through.
If there is no change in darkness at all while performing these tests, then the lenses are not polarized. Simply send an email to customer service, letting them know you already performed these steps and we are happy to exchange your lenses for you!
