Shopper How do you swap out the lenses out of this mask?
Rob S Instructions for installing these lenses can be found on Tusa's website. Go to support, then product manuals, and find it under mask lens replacement guides.
I used a slender pen as the "tool" for the first step which pushes up on a tab, then a thin screwdriver for around the frame and it worked well.
LeisurePro S The trade is easy enough. The center bridge piece (which holds together the frame and lenses) on the mask should snap off and then it will be a simple matter to pop the old lenses out and the new ones in and then replace the clip. Sometimes the plastic can be a little bit difficult to remove, but you just need to use a bit of force. Don't be scared, sometime the plastic can be hard to remove. If you're uncomfortable doing it, you should be able to take the mask to your local dive shop and they should be able to do teh switch in just a few minutes (and hopefully for free).
