I have progressive bifocals in heavy aviator frames, one non tinted and one tinted in gray at 50%. They are the same glasses except for the tint and this removes the few minutes of looking though a fishbowl that accompanies a change of glasses for me, since both are the same. I have an older pair with an 80% tint and they can be dangerous in a shaded spot or in a tunnel, but the 50% do fine. 50% is not enough to deal with direct sunlight though, so I sometimes add a pair of clip ons to them, and this sometimes make trouble with the top of the visor opening in the helmets. I think I'll get the next ones at 60%, that maybe the best compromise.
If you want to experiment you might want to check the cheap prescription glasses on the net from asia, that is what I did. It took me three tries to find my current combination, and I think I'm pretty close.
I use helmets with visors so I have no need of goggle types.
