Hi folks, I recently purchased a new pair of perscription sunglasses with polarized lenses. (They weren't cheap ones, ether...) The polarization on the lenses seem very uneven to me. If I look at a clear blue sky, I can see that the lenses looks splotchy, as if the direction of the polarization was not uniform throughout them. I see this as well if I examine them with a polarized camera filter. I've had polarized glasses before, and I've not noticed this, although it's not something I explicitly looked for. This pair seems particularly distracting - I've actually had these redone by the lab, with similar results both times. Before I take these back again, I'd like to know if I'm expecting too much. More specifically: - In general, how even should the polarization on perscription sunglasses be? - How much should a strongish perscription (~-5) affect the evenness of the polarization? - Would the fact that these are high IOR lenses affect how even a result I can expect? Thanks for any insight, -p
