(Relatively) inexpensive prescription polarized glasses?

Hi -- I'm looking to buy (relatively) inexpensive prescription
polarized glasses. If possible.

I know that "prescription polarized" and "inexpensive" are basically
oxymorons. But after much testing, it really seems like I'm going to
need two sets of glasses -- one for most of the day (brown or copper
lenses), and one for that crucial final hour or two (yellow or amber
lenses - when my vision is worst, because of the low light).

Photochromic helps, but even so, the lighter end of the scale on the
brown/coppers still seems to be pretty dark.

Action Optics run about ~$200 a pair for prescription. I've seen
others for more. Anyone seen / used any that were less expensive?

Thanks, Tim
