Is it just me or have the radarlock lenses become harder to switch? I have a pair of radarlocks from 2012 and, both then and now, the lenses are super easy to swap out, it takes almost no force at all. However I recently purchased some prizm road and trail lenses and it is virtually impossible to get them in. I end up having to wrench the frame and really force the lenses into the frame. Is anyone else experiencing this, or is it just me?
