With the advances of age, my near sight is going down. I realized recently that I shoot underwater with arms fully extended, otherwise I don't see the LCD in focus :-( While this extends my reach, it does not help the quality of the shooting.
Nauticam recently came out with an LCD magnifier that has diopter adjustment (which presumably can solve my problems) -- see http://wetpixel.com/...r-and-sunscreen
However, my housing model (NA-EPL3) is not supported for this magnifier, and as far as I can tell it would clash with some of the control buttons that are on the screen periphery (in the newer housing models they moved these further from the screen).
I am thinking of building a DIY version. Designing a shell that fits the screen and button layout was easy (and I plan to print one).

The question what type of glass to put on the viewing end (right now the top holds a 55-52mm stepdown ring (in light gray), that allows me to put in 52mm filters. One option is to use standard close-up filter (say +10). However, I am not sure how well this will perform underwater and it definitely would not be adjustable.
Any suggestions on a better mechanism?
