That way I could have the glasses on like normal, not perched on my nose ready to fall off if I changed position. The glasses were relatively cheap. 30 or 40 bucks. But the eye doctor to ge the prescription was another 45 or so. Cost out the door, close to $100, plus time. Removing the eye doctor, having the user just tune the lense themselves, seems to me to be a real advance in making them cheap. After that it is just a manufacturing problem, and in bulk they have to be done in the low 2 or 3 dollar range.

Their strength is indicated by color of the frames and some are bifocal. No correction for astigmatism at that price. http://daviddfriedman.blogspot.com/2007/04/price-of-eyeglasses.html Price may be at the bottom already. Maybe the real shortfall is lack of efficient distribution in countries where the socialist dictator keeps all supplies for the blessed or where illiteracy leaves a giant hole in solving simple problems.
