Hello Gene!  Still have the one piece Pronghorn I purchased from you last year!  Just shot it today.

I wear progressive bifocals and found they are of limited use for peripheral vision.  I must be looking straight ahead to see clearly.  This is unaceptable for wing shooting or even trying to look to the side without turning your head too much.

I ended up purchasing a pair of single vision polarized sunglasses to wear  for distance.  I still carry my regular eye glasses for very low light.

I have purchased at least 5 different pair of prescrption polarized sunglasses over the years.  By far, the best pair was my last (and current)from a store in your neck of the woods.  Bend Sports Vision is a prescription sunglass provide for Smith Action Optics (http://www.sportsvisionbend.com/)

This is by far the best pair of prescription glasses I have ever owned.  The lack of distortion with peripheral vision is incredible!  Plus with no prescription plan, I paid $285.  I paid much more for glasses of lower quality.  They have a lot of styles to choose from, and I believe they make regular presciption eye wear as well.  

Unfortunately, I will likely need cataract surgery this year and will need all new glasses.  Docator may not be able to entirely correct for astigmatism.

Good luck!

progressive tri-focals   :cool:
