Can anyone provide a description of how to change Half-X lenses? I got a pair of replacement lenses and they didn't come with any instructions. There is a tutorial on youtube, but they are using Walleva lenses and bending them like crazy (which doesn't seem like an option with Oakley lenses). I tried removing the T6 screws and installing the lenses that way...but it was a nightmare reassembling the gasket/screw combo while holding the lens in place. For the other lens, I tried bending it into place, as shown on youtube, but managed to scrape some of the iridium coating off the outer edge of the lens I noticed that there is a tiny gap between the lens and the orbital edge of the frame. Is this normal? There's got to be a better way.
