Your astigmatism should go away under water, since it is a refractive problem in the eye and your eye's refractive elements hardly matter underwater (which is why we need lenses).

I am guessing that the stand-offs were used to hold the lens away from the surface of the goggles. This would allow the fluid in the goggle to competely surround the lens and it eliminates the possibility of an air bubble. It probably also adjusts the focus of the sysetem a bit, putting the lens very close to the eye. In fact, by making a stand-off that allows the distance between the eye and the lens to be adjusted, I think that the lens can be "tuned" so that you can compensate for vision problems ike nearsightedness and farsightedness.

Hmm, per Doug's post, it seems that I put the lens in backwards
