I get my hearing and vision issues taken care of by the VA. As the VA here in Grand Junction does not have a vision section they outsource their patients to the local community. I have used Gray Eye Care on Wellington for my vision needs. While I get my normal glasses though them at no cost, I ordered a pair of prescription sunglasses from them that I have to pay for. They are polarized and great (for driving as well as fishing). I imagine going to any good eye doctor you can get a prescription for polarized sunglasses that will fit your needs. May cost a bit but well worth it.
