One evening about a year ago, I found myself trying on glasses frames for about two hours in my apartment. I don’t even wear glasses. But my former roommate Victor does. He had ordered five pairs of frames from Warby Parker as part of their free five-day home try-on offer. I thought this was the coolest thing; I’d certainly never heard of anything like it. And as a college gonfiabili student with no discernible income, being able to try on glasses at home for free was pretty damn great, even if I wasn’t looking for glasses in the first place.

Victor and I tried on all five pairs he ordered and explored dozens of other designs on the Warby Parker website. I had to wonder: what was the reason behind such an awesome try-on offer? Their company story is fascinating. It began when the founders’ frustration with crazy-expensive glasses finally boiled over. They wanted to make sight—a basic necessity—more readily accessible to those in need of glasses. And so they did.
