Buy lightweight frames and lenses, have progressives and get anti-glare coating and "we'd be back to paying $700/pair" is like, last year if I miss a sale. Lenscrafters, not a small shop. They're all owned by the same site, and I work on the 50% off of lenses sale. Frames are 150-300 as I avoid big-name style. These are way more than +2.5 diopter reading glasses, and you might imagine that astigmatism and progressives does wonders for straight lines...
