Simple diopter lenses are fairly useless for astigmatism correction.

Yup, but is that a large part of the population? I don't know the answer. In our house we are 3 for 3 so far with my wife, son, and me all using the cheap glasses

Probably not the way to go though if you have a complicated eye issue. But we are all just near-sighted ranging from -1 to -2 diopters.

I still think you'd do better, as would your brain with an actual refraction to determine what your correct prescription is... Just saying.. Yes, prescription glasses are hugely expensive! (It is a racket/ripoff)! IMHO. They can set you back hundreds of dollars! So, I don't blame you for going that route... but... you'd probably see better with a proper prescription...
