It wasn't that long ago when the notion of buying prescription glasses online seemed preposterous. Then along came Zenni Optical in 2003 and the industry was changed forever. Started by a pair of scientists in the same San Francisco Bay Area where so many other disruptive companies have been founded over the past couple decades, Zenni Optical had a simple, yet profound mission: To sell glasses that were fashionable and effective at a low cost. Suffice it to say they have succeeded. Zenni Optical developed an innovative productin process that proved to be a game-changer.
