    Photochromatic shields are great, but if you're using a dark tinted shield currently, it won't go nearly that dark. Think of the lightly tinted shields that many brands offer (but no one actually buys). They're gotten really fast and responsive though. With the original ones you'd ride into a tunnel and you'd might as well have your eyes closed. ICON makes one now too.

    Drop down visors are nice too, but you'll end up with a helmet that is noticeably bigger and heavier as a result.

    Re: Photochromatic shields

    I'd put mine at about 75-80% of the way between a Shoei light smoke and a Shoei dark smoke. Put it this way... on track day photos I could not see my face at all through a dark shield. I can barely make out some features through the Transitions. So it's not like a light smoke at all... those may as well be clear.

    Certainly dark enough to prevent eyestrain on sunny days. It's also temperature dependent, I think. Colder is darker.

    This has not been my experience in the past 6 (or more) years using the Bell transitions. From my understanding, usage, and a quick googling, it is purely based on UV light.

    I just looked it up and I got it wrong... colder is slower, not darker.

    Photos for reference so you can see how dark the shield gets.

    Red helmet has the Transitions. Look closely and you can see my face.
    Red/white/blue helmet is a Shoei dark smoke.

    Both shot this year. Both days were bright overcast... soft shadows, no direct sunlight.

    Nor will you... Hogging out a section of the impact absorbing materiel, to fit the dark visor, compromises the helmet's ability to protect your noggin.

    That's not true of all helmets with drop down visors. The Shoei GT-AIR has the same level of impact material as the other helmets, they just increased shell size in the front to compensate for the space for the drop down visor.
