Ngl I bet you could 3d print frames for like $1. Heck, buy some dollar store sunglasses and rip the lenses out and use em.
We need cheaper glass frame options
You go on Zennioptical.com, you pick one of the option under $15 dollar and you pick lenses with no coating.
You pay, wait a few weeks and receive your glasses in your mail box.
But if it's too much you can pick a cheaper frame, they have glasses+lenses starting a $7 I think.
Or save more money by accepting that one can’t see properly and live with it. Lol
