So here's the question.
If we can walk into nearly any drug store and pick up a pair of cheaters with a range of magnification options ( +1.00 to +3.00 ), why is it so hard to find a pair of O.T.C. polarized cheaters?

I'm not talking about a pair of bifocal sunglasses with polarized lenses, but a full lens with a single magnification power.

It seems to me if something like Dr. Dean's go for twenty bucks a pop, then a polarized pair of sunglasses sporting better optical quality magnifying lenses should be able to be found for say, fifty to one hundred forty dollars.

Any suggestions along those lines?
Are there any out there that answer to this description that I'm simply missing in my search?

Thank you, Dave

I know there are Rx versions available from Smith / Action Optics and others. I already have three pairs of S / A.O.'s and they're great, but for this I don't need a Rx.
