Extra Active Transition Sunglasses

I'm looking for a new set of RX sunglasses, and I'm considering these Transitions that claim to work behind windshields. I can't find much information about how they work in an airline cockpit- such as do they get dark enough in the bright light, do they get clear enough to still wear at night, or below the weather?

I like the idea of maybe being able to avoid ripping off the sunglasses and throwing on the normal glasses at otherwise busy times. I'm hoping this might work in some of those cases, but I'd like to get first hand knowledge before dropping a bunch of money.

"Transitions" lenses darken with exposure to UV light. Also, the level of darkness (tinting) is affected by OAT. Cooler temps = darker lenses. Having said that, Transitions do not darken while in the cockpit OR while in a vehicle because most aircraft and cars nowadays have UV blocking windows/windscreens.

I'm talking specifically about the Extra Active lenses that are different than the ones that you are talking about. I'm talking about the ones that darken behind a windshield because they are activated by ambient light as well as UV. Since there is ambient light in a cockpit, they should darken just fine. I just want to know if they get dark enough for flying and get opinions on how hey work in real life.
