Any question answered...

Has anyone used cycling glasses with interchangable lenses where the lens attaches via little protrusions on the outside edges? Mine bend and a few have broken from changing lenses. Is there anything that can be done here - seems a pretty crap feature.

Yeah, I have 2 sets of the lenses for a Bloc frame I lost/broke.

Gave up in the end and went for something more regular - they didn't do a polarised lens for the interchangeable one anyway.

Also, £150? Say what? These were more like £50 and I still thought they were pricey.
