I'd just like to know before undertaking the task. Usually it makes it
easier and then I won't have to break the current lens that's on it,
hehe. Thanks all.

I have two sets of A-frames and it's not the easiest of tasks (lots of
careful, but forcefully stretching of the goggles). Don't worry about
the lens, they are pretty tough and durable, the thing you need to be
careful of is not to tear/damage the little nubs that hold the lens in
place. When I was shopping for a replacement lens, I found that I could
buy a whole new pair of A-frames for less at Overstock.com.
