Just had lenses made for my Knobloch shooting glasses, only £15 for two different strengths, 2 way postage included from:-

Best to send the lens and lens holder as I just sent a sample lens and the new ones came back slightly small and needed a little packing added for the holder to grip. Otherwise, 100% and better than the £30 odd (?) each I've heard quoted elsewhere.

At first I thought they had screwed up with the prescription, but they had put the datum mark for astig. correction at 9 o'clock when I expected it to be at 12 o'clock!
