I agree with Doc's assessment of the delicate nature of the mask, but I'm
not sure a tech will do better, or protect you if things go bad.  I have two
of the masks and changing the lenses is pretty simple.  I'll check for sure
when I'm  home, but my recollection is that you remove the clip in the
center of the top of the mask and the frame, which holds everything
together, separates from the mask.   You then replace the  lenses, replace
the frame and replace the clip.  The clip and frame are at risk.  If my
instructions are not obviously right when you look at your mask, DON'T
FOLLOW THEM.   I don't have a mask in front of me.

I hope you have  the original lenses.   I ran into this problem when I did
the same thing you're doing.  I bought a mask with perscription lenses in it
for my father.  He returned it when he had an eye operation that improved
his vision enough that  he didn't need the lenses any more.  A friend wanted
the same  lenses and wished to swap some standard ones for them.  It turned
out that her mask was newer than mine and lenses were not interchangeable.
We swapped masks instead.  I didn't really want a pink mask and she didn't
really want a red  one, but both of us got something usable in the trade.

Yes...I agree...upon further evaluation, I will let the experts handle
it.  Trying to be a penny pincher is not always the best route.
