In reply to RockingKatja:
Cheers guys. Haha. It didn't even occur to me to bend the sides, since I never had such glasses. I've bent them very causiously now and it works. Feel like an idiot. Been wearing glasses since I was a child, but never had glacier ones.
Will still check out those links
PS: They're not only for Scottish Winter, but also for Bolivia, Acon, Island Peak etc.
