Cool, I could just tell you had more information/better understanding than many. I knew you must be in the business somehow.
Can someone explain polarized lenses?

So are you saying that to your knowledge, there are no manufacturers out there (Ray Ban, specifically) that utilize a spray-on polarization process or "coating"?
I wonder how Persol lenses compare to other polarized lenses out there. Anyone know?
As far as I know, no. But I will ask. I don't see how it would be possible or practical when the current internal film technology is so effective and inexpensive. Ray-Ban is owned by the company for which I work. They offer a few A/R and scratch/smudge resistant coatings. I suspect the most expensive is on their new P 3 and P 3Plus lenses. According to their ad info:
P 3 and P 3Plus lenses are the highest quality level of Polarized lenses, equipped with anti-reflective and hydro-oleophobic coatings. And the P3Plus lenses add a high-color enhancement(available only on new Tech Collection, Craft Collection and Ultra Limited Edition).
btw: hydro-oleophobic means the coating repels water and oil

Thanks. This whole subject has me interested. The limited research I've done on the internet refers to two different types of polarization that would seem to indicate that there are some lenses that are treated by a spray on coating that is different from the internally layered polarization.

I hear occasionally that people get headaches from using polarized sunglasses. Anyone else hear this or experience this?
The people that get the headaches only get them with certain polarized lenses and not others which is confusing.
I was also at a store that sold Costa Del Mar and the store associate said that some people complain that Costa's polarized lens give them headaches.

if you want beach/fishing glasses best glasses to cut glare is costa del mar. I have polarized oakleys i got them cheap if not i wouldve gone with the costas. Cheaper glasses have cheaper lens.
I've had that experience before.
Such a bummer, driving along on vacation, seeing such great scenery, stopping to take a photo of the great sunset or whatever, taking off the sunglasses ... meh.
Perhaps there's a similar polarised filter one can pop onto one's camera?
Polarized filters are quite common for cameras. Almost a necessity when shooting on open water.
They also sell them as fishing glasses allowing you to see deeper into the water.
If you take polarized sunglasses and rotate them you will see the effect change.
Most camera filters are designed to rotate to increase or decrease the degree of polarization depending on the effect you want. Usually polarization increases contrast so blue sky is much darker and clouds are much whiter. The effect can be dramatic.

I prefer to look at the world through rose colored glasses!
The bad part of polarized lenses happens while driving. When I look through ther rearview mirror I can see the tint on the back window. That is one way to check if your lenses are polarized.
Boy, this old thread sure came roaring back from the dead.

I had an expensive pair of polarized sunglasses from The Bon Ton years ago. Wore them to Ocean City, was standing on a rock by water on the beach and a big wave smacked me, knocked me back about 15 feet and stripped the coating off my lenses! 
That was the last time I bought a pricey pair of glasses...now I spend $10-15 and treat them as disposable...because sunglasses of any price seem to end up being disposable anyways.

I never bought expensive sunglasses before, but last year my fiancee who works for her dad and uncle who are optometrists and loves her sunglasses (and buying new ones) bought me a pair of Maui Jims with the brown lenses and I have to say they are amazing. I am pretty sensitive to bright light, so I wear them everyday. I times I notice the biggest difference is when I am driving. They cut the glare so well and reduce eye fatigue.
