Changing lenses on a XL-1?

Hi all,

How do I change lenses on the XL-1? Instructions are included, which basically tell to push the lenses out while stretching the frame but the frame doesn’t seem very flexible… Quite rigid actually…
Do I just apply force? Don’ wanna damage my spanking new glasses… 8)

Looks so easy on this video… Perhaps it gets easier after having done it a few times? That that loosens up the frame?

One of the reasons I went for the XL-1 is the possibility to switch out the lenses with clear ones. After wearing glasses for > 25 years now, I know there are some situations where wearing glasses just comes in handy! 8)
