Remember that a magnifying glass has much less magnification UW as the density of water is much closer to glass than air.
If you run a search here you'll find a DIY design that put 2 lenses into a tube with an air-space between them.

I dive with a jeweler's loupe. Small enough to keep in my bc pocket, enough magnification to bring those tiny nudis, crabs, fishies up-close and personal. The one I carry now is a 20x. I have to get awfully close to focus, but it works fine most of the time.
Have used different powers, different descriptions, and different sizes. All magnified the items I viewed and opened up a whole new underwater world for me. (Thank you, Bill!)
I've purchased from ebay, craft store and a local jewelers' supply.
Never dive without one, if I can help it.

Wes Pratt (then of the NMFS lab at Narragansett, RI; now at Mote Marine in the Keys) designed and built one back in the 1970s that worked well underwater. I think it was marketed for a while. Call Mote and ask for H. Wes Pratt ... he can likely help you.

This is the one we use, Carson MagniFlip 3x Flip-Open Pocket Magnifier with Built-in Case. , . Carson Magnifiers.
It has the advantages of being small, a built in lens protector, mostly plastic and is cheap.

I think I'd drop a couple more $$ and get this magnifier. Carson TriView 5x / 10x / 15x Folding Loupe with Built-in Case TV-15. . Carson Magnifiers.
In fact, I might get a couple of these myself! Nice to share.....

Thanks, driftwood, for the resource!

The cheap plastic is the case. Lens is glass, as usual... if I am understanding question and description.
