Mrscarlos has 2 nice pairs , a titanium square wire with titanium iridium lens and a why3 with ice iridium lens. She bought both pairs at the same time with some redundancy money years ago and they’re both still like brand new.
Mine broke within a fortnight – lens popped out of the frame. Loose fit but Oakley wouldn’t replace under warranty, claiming I’d trodden on them or something. So check the lenses are firmly in place before you leave the shop.
