My experiences in the US in 2015 and prior: * Took exams, but didn't receive PD (pupillary distance). Had to take another exam and specifically ask in order to receive that. * Frames from most places except Walmart were disproportionately expensive, and walmart's styles... were lacking. Only select styles were reasonably priced. * Nowadays my family in the US uses Warby Parker. Last time I used it the prices were reasonable, one just needed their pupillary distance measurement and an eye exam taken within one year. * For both Warby parker & brick and mortar shops, you had to wait for the new glasses to come in. * The process for contacts was better, but still quite expensive. I had to drive to the eye exam so I couldn't do the enlarged pupil process. My experience in Korea in 2018: * I walked into a random glasses store, picked out a pair of frames, gave my old glasses to the clerk in order to scan them, waited 10 minutes, and then walked out with thin, good-looking, strong-prescription glasses for $80. Couldn't have been easier or more straightforward. * This year I plan to get contacts to see what the process is.
