San Francisco pioneer DTC online eyewear at $6.95+ complete glasses with 50M+ pairs sold; privately-held disrupting traditional optical retail competing with Warby Parker and EyeBuyDirect for affordable prescription glasses online.
Zenni Optical is a San Francisco-based direct-to-consumer online eyewear retailer — privately held, founded in 2003 by Jing Wang and Julia Zhen — pioneering the online prescription glasses market by offering hundreds of frame styles with prescription lens fulfillment starting from as low as $6.95, making vision correction accessible at a fraction of the $200-800+ price of traditional optical retail. Estimated at $400+ million in annual revenue with 50+ million pairs of glasses sold to 50+ million customers in over 50 countries, Zenni's low-cost manufacturing (frames produced at owned factories in China) and direct-to-consumer model (no distributor or retailer markup layers) enable the dramatic price advantage over LensCrafters, Sunglass Hut, and independent opticians that made Zenni one of the first successful DTC disruptors.
