The sunglasses look ok initially – I love the retro mock-tortoiseshell frames, but something niggles me, so I send an email to them querying it.
He assured me that – to an extent – this is normal, and is caused by stress, in making the lens and fitting it to the frame.
As he is speaking to me, I notice something else.
“OK, I said, but shouldn’t the polarization of both lenses be aligned to the same plane?”
“Yes,” he said. “Otherwise – depending on the polarisation of a light source or glare, one eye could appear darker than the other.”
“That’s what I am seeing,” I say. “I’m rotating them in front of my LCD screen, and the as they rotate the left hand lens is getting darker and lighter about 20 degrees before the right hand lens.”
“OK, that’s wrong. I’ll raise a return ticket, so you can send them back.”
Sigh. One part of me is frustrated that there is a problem. However, I do appreciate good customer service, and this is definitely it. The return ticket, with a pdf freepost label, arrived by email in minutes.
