I need your expert advice, please. I need a pair of everything-proof sunglasses - by which I mean they stay on when I bend down, and the tolerate being pushed up on my head when I go inside (yes, I know you shouldn't do that, but I do and I can't see my breaking the habit) and won't be detroyed by being dropped once or twice. I have a pair of Bulgari wrap-around ones which, whilst beautiful and desirable and all that are entirely useless for anything other than sitting still as they fall off too easily (and they can't be adjusted). Since it is nearly my birthday, I thought I might as well add a decent pair to my wish list rather than ending up buying myself cheap and nasty ones in desperation...
All suggestions welcome - what brand(s) should I be looking at?
