I’m a huge fan of the Specialized Adaptalite – I think I have the singletracks or chicanes. I previously came from Oakley Pro Racing Jackets (with the vented lenses), but switched because, well, the Specialized glasses sounded good, and I made a bit of cash by selling the Oakleys and buying the Specialized specs (new).
The yellow tint is good under the trees – think Wales on a grey raining day – but dark enough that in photos of me wearing them skiing, they actually look like “conventional” sunglasses (ie darker lenses). I guess the key is that the transition between the states isn’t really noticeable. And you can’t argue with the theory that as the photocromatic mixture is embedded in the lens (rather than coated), they should work well even if you do rub the lenses a lot.
I’ve not scratched mine yet, and although I had previously been a big fan of the Oakley optics (and lens clarity – I had nothing but Oakleys for about 10 years), I really don’t notice any difference in that area.
Downsides – they still fog up if you’re not moving, especially when it’s really cold (like for skiing). And to be honest, this particular model looks a bit daft off the bike – think Jude Joooools’ big glasses, only with a yellow lens. But I like ’em so much I’ve been vaguely looking around to see if I can find a model that would work as an everyday/ off the bike pair as well.
Edit: sorry, got a bit carried away there. er… I’m a fan of them, as you can see 🙂
