I guess I never noticed. I always wear a ball cap when driving, always have before wearing glasses. Just another tool I use and have not given it much thought.
They will also go dark when it’s overcast outside because they react to UV and not visible light. So your glasses will get dark when it’s already cloudy, which is not great
They kinda suck for driving though, because they don’t turn dark inside a car.
