Even prescription glasses don't always correct astigmatism.... I thought my red-dot sights were fuzzy because they were cheap, until I saw the YouTube video and realised I had an astigmatism.
I had an eye test a few weeks ago as I thought my sight in my shooting (right) eye was deteriorating.
The local optician said my eyes hadn't changed, and when i mentioned astigmatism, he said i'd always had it...
I wasn't happy with that, so went to Vision Express and had another eye test... they said they could correct the astigmatism, and while testing my right eye diagnosed cataracts forming..
I eventually got the glasses from Vision Express... and my red-dots are still fuzzy...

I have seen but not tried these glasses. They looked well made and ergonomic to me.
I don't know the price but if they are a lower cost alternative to the foreign competition, so much the better.
As explained, if you can use "readers" lenses then do so but, if not, you can still have Specsavers (other optician are available) make you a prescription lens.
My branch of Specsavers (as before) were completely unfased by me producing my pistol to get the lens absolutely right. (0.25 different from their estimate).
Good luck to the maker, I hope he succeeds.
My red dot sight was also oval until I got my astigmatism corrected, now it's very nearly round.
