Yes there were some threads about this but I can't find them at the moment. Talk to a good optomitrist, I would avoid the chain-type stores that you find at most malls. There are lots and lots of lens options out there, you should have a good long talk and discuss all the possibilities.
I have not liked the transitions lenses, they have a subtle tint to them which bothers me because I'm picky about that kind of thing (accurate greyscales for instance). If you have bad vision (like me), there isn't really too great a way to get around chromatic shifting and barrel distortion, that's what really bugs me and I've not found a good solution to that since you just have to go with a high index material or your glasses will weigh a billion tons.
