Louis: 'Your Oakleys are not polarised, you would know if they were because they are way more expensive than normal lenses.'
Louis : 'You know how they're made? The crystals are aligned in one plane so that they only transmit light in that plane?'
Louis : 'Also you can see fish with polarised lenses because they cut through the glare caused by scattered reflections from the surface of the water. Can you see fish with your glasses? I don't think so.'
Louis : 'The way to tell is to hold your lens up behind a pair that you know are polarised and turn your lens through 90 degrees, if they go darker then both lenses polarised, trust me, I'm a Physics teacher.'
Jenny: 'It says 'Polarised' on the lens.'

Louis : 'Or you could pop one of your lenses out and try it against the other lens but that's a bit of a faff, so I probably wouldn't bother, just accept it.'
