Hey John
Yeah, I know that aging thing.
I wear +1 or +1.5 glasses now for reading. I was finding problems reading the various labels on my housing and the top LCD. A visit to an optician told me that for that sort of distance I needed +2 which I then had fixed to the bottom half of a new mask. Works well although took some getting used to.
Like I say, half lenses in effect. I do wonder if you go with a full lens at +2 and you have good long distance vision (as I do), you may well start to feel nauseated over the length of a dive by the blurry long-distance vision. I think I'd be wary.
