Most dive shops can get this done.
You pick a mask that fits and they send it off with your prescription
numbers and get lenses stuck to the inside of the glass. I'm on my
second one now.

You probably need to talk to somebody who knows the ropes not
the DM intern serving behind the counter.

I and -4 and have astigmatism, and for the 18 years I have just been buying
masks off the shelf in dive shops using stock lenses.

You don't get the astigmatism correction (which does not seem to matter to
me, I can still read run times), the murkyness in the water is about the
same as my astigmatism !

You do get to walk away with the mask there and then and its pretty cheap
(an extra 30 to 40 quid on the price of the mask)

I've used Tusa Lunas for a while (quite low volume), but I have seen loads
of 2 pane mask that except stock lenses

If you are not an experienced diver, make sure the mask fits. ANY mask will
fit if you push it your face and breathe in. Just place it on your face,
suck and see if it falls off. If it does not, look in the mirror and check
that there is some clearance between the bottom of your nostrils and the
silicone skirt - the gap makes clearing easier (hope no egg sucking
education there)

Most dive shops can order and fit corrective lenses to the mask of your
choice. Don't worry about compensating for astigmatism or getting perfect
vision, you won't notice the lack of it in the far from perfect visibility
of UK waters, and even in clear tropical waters it has been the visibility
of the water not the imperfect lenses that have limited my vision.

Get Lasik treatment ... I did, it's far better, and great in or out of
the water.

I got mine from www.simplyscuba.com bought a TUSA Platina Mask which is very
low profile and added the following lenses. They fit them before dispatch
and they took around a week to arrive.
