The researchers hope to make the technology small enough that autofocals will be comfortable to wear all day. Stanford electrical engineer Gordon Wetzstein reckons it’ll take a few years before we see autofocal glasses that are energy efficient, lightweight and, perhaps most importantly for something we have on our faces all the time, stylish. If companies can pack smart glasses tech into normal-looking frames, it certainly seems likely autofocals will be a snazzy enough option down the line.
A single pair of autofocals might also be enough to last for decades even as your prescription changes. “This technology could affect billions of people’s lives in a meaningful way that most techno-gadgets never will,” Wetzstein said.
