Er, the lenses are still stupid cheap. I literally paid $50 all told for both frames and lenses. And I just searched for online budget retailers here in Australia, went with the first result, and their single vision lenses (even with my current prescription which is a bit fucked cos my eyes are vastly different and one of them is so bad the lens may as well be the bottom of a coke bottle) start at $AUD9.95. Bifocal is a bit more expensive, but still quite reasonable with prices starting at $AUD42. Sure, they have fancy Kodak lenses for $AUD280, and getting coatings and UV coating costs more (I still say that $AUD80 for the ultra premium ones with added blue light filtering and all those bells and whistles is “cheap” compared to what I used to pay), but there is no reason you can’t get a pair for under $AUD50 that’ll do you just fine.
