I have done a few rides with the glasses and am having problems with my glasses bouncing up and down and losing my focus (an thus going slow). I looked at the Pro-vue page, but I'm not sure how the lenses are attached to the frame. I typically take 3 or 4 pare of goggles to a race (or ride) and switch out at gas stops to get a clean lense and foam that isn't sweat-soaked, could I just swith the lenses out with each new frame?

we are alike with the going slow part...except for me thats got nothing to do with goggles:confused:
The pro-vues really are not really built for a quickie swap - i guess if you got better at it than i am it could be done though. what they do is a clear plastic lens, similar to a goggle lens, but thicker plastic, sets behind the normal goggle lens. This second lens then has inserted into it, two prescription lens that looks basically like what is in your glasses - the prescription ground lens kinda snap into that larger insert into holes cut to the shape of the prescription lens. two screws then go through holes in the goggle lens and hold the insert in place.
to take out the insert you first undo the screws, work the standard goggle lens out, put the insert with the prescription lens into the frame, put the standard goggle lens in place, then snug up the screws. It seems you should be able to pull the insert out the back of the goggles after the screws are removed but without removing the goggle lens. For some reason Pro Vue tells you not to do it that way (dunno why?). I suspect its because you risk flexing the insert to much and chance of cracking it.
Here's a chance to invent something... a way to attach fresh foam to your goggles easily! pull off the sweat soaked stuff, stick on some fresh stuff!
