Take-a-look and progressives here and it works great for me. Mirror is high enough to be in the distance zone of the glasses outside of any distortion. But my prescription is moderate and individuals with stronger prescriptions might have issues I don't.
The mirror is "right there" regardless of which bike I'm riding and moving my head slightly allows scanning a wide full-scale view rather than a demagnifed view convex mirrors provide.
