Have Transitions (about a year old) in one pair of glasses. As others have said, they do NOT go 100% clear but are a lot clearer than the previous generation coatings.
One big problem with Transitions (or any other changing lenses) is that they don't work in the car. Most widows are UV filtering so the Transitions won't change. To solve that, I just kept a pair of clip-on sunglasses in my car. Sucks when you get in someone else's car and you didn't grab the clip-ons.
Overall, they aren't bad. They don't get as dark as I'd like. My wife says they change half-way under some light conditions and then you look like a "child molester in 70's style glasses". I tend to not wear them as much as my current ones, but they are nice for days when I'm constantly going in and outdoors.
