I also wear glasses with progressive lenses.

I dont use the verifier lens when hunting but I do use a number 1 clarifier when I am using a 6x lens in my sight.

They do sell a kit that has a lot of the stuff already in it but its not cheap.
That would be one way to go as you can play around with different strenghts to see which one suits you best.

Rather than emailing them give them a call on 800-555-2856 I have found they are really good with their customer service and will answer any questions you have plus make a reccomendation on the info you give them.
