Eyewear Tech at CES

Although wearable technology is small, portable and personal, it made an outsized impression at this year’s International CES, the annual consumer electronics show held each January in Las Vegas. Amid acres of oversized curved screen monitors, smart cars and internet-connected home appliances, wearable devices—notably eyewear—drew the attention of many of the show’s 150,000-plus attendees, many of them savvy, tech industry veterans.

The variety of tech-enabled eyewear on display was impressive, ranging from augmented reality glasses with heads-up displays designed for everyday use to immersive virtual reality goggles meant for gaming and movies to eye tracking systems that detect precisely what the wearer is seeing.
