I have astigmatism, which since it got worse, contacts do not play ball well with, always a notable difference from glasses.
You should be able to get a set for ~£150;
I run Revision Stingerhawk ~£60
insert with connector system ~£25
Glazing insert ~£60 upwards if you need or would thinned lenses
+shipping bits to you.
Depending on your prescription depends on if you need thinned or even if an outlet will touch them.
Specsavers are hit and miss for taking it on, I think they only deal with safe prescriptions on the low end.
Your best bet is visiting a local smaller chain or individual opticians, sport stores, possibly even shooting/gun stores as they are most likely to know where to go.
I have a small opticians lab/outlet near me which if you get real stuck I can pass you their contact details for glazing. Which might be worth saying where you based.
2 lens as in eyepro+prescription, pretty much everything will fog. EXFOG IS GOD SEND AND WORTH EVERY PENNY. There are knock-offs. I've had mine for about 4 years and now wouldn't be without it.
Your only real other alternative to this is a dye mask that you can fit or normal glasses in underneath. There is eyepro designed to go over your glasses but I cannot speak of their safety ratings, tightness, or antifogging properties.
