I've got a pair with photochromatic lenses & have to say they are mint. I bought mine initially purely for cycling but now use them for loads of other things. Have found them particularly good at things like festivals too as a) The lens adjusts to the light condition so you don't have to worry when the sun goes down b) It freaks out the trippers / pillheads when the lenses change colour.
Their customer service is also excellent (I don't work for them).
Definitely agree with Mr Tom's earlier post for Optilabs http://www.optilabs.com/
