You will want to be careful when you get your goggles.  Speak to someone
very familiar with RX goggle lenses.  When I inquired about getting mine
made, it was indicated to me that the water-to-glass-to-air setup with
goggles underwater is good for about -1 diopter already so I don't know
if they figure that in when making them or not.  Since you'll be using
the above water, you will want them to be accurate.  My correction is
only -1 so I ended up not having RX lenses made and I can say that
underwater I see fine without correction.
