Checking if PenSee Sunglasses are Polarized
I recently received a pair of sunglasses that I purchased on ebay from pensee_eyeglasses_au and suspected they were not Polarized as advertised, both in the advert and on the box I received them in. I questioned them about this and they requested I prove they are not polarized, so this is the video to attempt to demonstrate this. Viewer beware - this video INCORRECTLY states that this is a test to see if the sunglasses are UV protected, when it only tests to see if the glasses are polarized (brought to my attention by Chubby Luna - thanks Chubby Luna). As Chubby Luna points out, you need a UV digital photometer to evaluate the UV protection provided by a lens.
I used the technique found here
