McDave, that makes a ton of sense, and possibly explains another difficulty I have (shooting from and elevation). I grew up with a recurve in hand, but have only hunted deer with a compound. I have attributed my being able to shoot a compound very well from a treestand to the proper alignment achieved by using a peep sight and front sight. While that will benefit any archer, it possibly is especially beneficial to one wearing progressive lenses. On the other hand, shooting a bare bow could be much harder without the benefit of forced alignment of a peep and front sight. As I reflect on this, the only thing that ever bothered me about wearing progressive lenses was when I looked straight down from a treestand. Odd thing is, wearing progressive lenses never interfered with me when I use to play a lot of tennis.
