Not all progressive lens are the same and there are differences in quality of different manufacturers.
I found the Essilor Varilux progressive lens to be the best after my cataract surgery for shooting.
Sharp vision - right to the edge of the lens or whether viewing long distance or close.
Seamless transitions - no break like bifocals or abrupt transitions
Wide fields of vision - better able to detect wind peripherally
Stability of vision in motion - stable perception of what you are viewing despite continuous eye movements, head movements, or even body movement.
Most of the time you are sighting your rifle by looking through the top right of your lens.
The majority of lens have edge deviations in the quality of focus but the Essilor Varilux are extremely shrarp providing much mor accurate ability to focus as you use the edges of your lens.

I plan to go back to the Essilor Varilux lens.
