A few weeks ago my helmet struck the final blow to my previous pair of dodgy sunnies - having stretched them until they didn't actually stay on my head without a helmet holding them on (and even then barely) and compressed them to the point that the lense came out whenever I put them in my pocket, I finally lost a lense on the road and it was new sunnies time. Not wanting to destroy another pair, I figured sunnies sold to the ADF and rated up to 40m/s for impacts would probably stay together reasonably well - I did a search on NetRider and came up with nothing but positive reviews, so I gave them a go. Bad idea. They're the worst sunglasses I've ever had. I imagine a lot of this must be just due to my face - maybe I'm not fugly enough? I really didn't think the proportion of my nose and eyes was that different to everyone else, but they fit horribly off the bike and even worse on it. The bottom edge of them comes down to about the middle of my eye, and the foam stuck to the frames sits there so my eyelashes hit it whenever I blink. Annoying. When I slide them in between the helmet lining and my face they dig into my head, and every time I check my blind spot they come out a bit and the frames block my peripheral vision. Moreover, as soon as I put them on they start fogging up, and in a minute or so I can barely see through them. I've got no idea where the fog even comes from, I guess it's because the foam forms a seal around my eye? I've gone on a few rides with them thinking "cmon, give it a go" and had to take them off, because in between the fog and not being able to check my blindspots properly it's just dangerous to wear them. Other people have posted positive reviews, so I imagine they're sweet as long as the position of your nose and eyes lines up properly. I'm just posting this so someone searching through the threads here doesn't make the mistake of assuming they're fine for everyone like I did. tl;dr - just wasted $59.95 buying sunglasses that didn't fit me, hurrr.
