“Imagine all the people seeing 20/20.” With its instant-prescription John Lennon eyeglasses, a company called Adlens is hoping to do more than imagine. Dials on the frames of the glasses adjust liquid inside the lenses to achieve prescription-accurate vision correction for either nearsightedness or farsightedness—which is a cool trick in itself. Yet for every pair purchased, Adlens is also sending a second pair to Rwanda, where an estimated 1 million citizens need glasses. The Lennon frames are Yoko Ono–approved, but two other styles are available. And don’t worry: The bulky dials are removable once the lenses have been set.
