New glasses needed ASAP

As I've tried to struggle on for a couple weeks without wearing my old glasses - the left lens continually pops out, distorting my vision (as well as occasionally pinching my eyebrows) - my left eye has grown very sore, probably as a result of having to overcompensate for my useless right eye. It doesn't feel great, and I wish Lenscrafter would hurry the hell up and get my glasses done. The soreness is fairly constant by this point, which makes having my eyes open a vaguely unpleasant experience.
