Dive Mask Magnifier
 
I needed a hands-free magnifier that I could move out of the way when cruising around looking for critters. I came up with this.

For some reason, it was getting hard for me to read my dive computer and see my camera settings. They tell me it could be age related but I'm not sure.

Look for reading glasses with the strongest magnification possible. The best I've found is X3.
I found some with titanium frames and lenses that are held in place with screws and nuts. This allows "easy" swapping of scratched lenses.
I have found that the screws in the joint are the first thing to rust out.

I use a piece of bicycle inner tube to hold all of the pieces in place.

Minor modifications were needed on the mask.

The zip tie holds it in place.
