Bloomberg reports that Warby Parker, the U.S. omnichannel optical retailer, is planning to open more than 30 brick-and-mortar stores in the country before the end of the year, which would bring its total number of retails locations up to roughly 160. Neil Blumenthal, a founder and co-CEO of the company, said that there was still room for Warby Parker to open hundreds of stores and that, if the vast majority of Americans need glasses, they prefer to buy them in stores. The new stores are expected to have trained eye doctors on site, as is already the case in about 80 of the company’s locations. According to the financial newspaper’s estimates, Warby Parker’s year-on-year revenue growth has slowed down from about 100 percent in 2013 to an average 25 percent in the 2016-2019 period. In 2020, sales growth hit a bottom 7 percent because of the Covid-19 crisis but rebounded to about 40 percent in the current year. The company announced last month that it had filed a confidential application to the U.S. Security and Exchange Commission in view of a future initial public offering (IPO).
