LAS VEGAS—Innovative vision technology is becoming more and more visible every year at CES, the annual mega meeting and trade show which drew more than 180,000 attendees here earlier this month. Although attendees marveled at spectacular exhibits featuring consumer electronics products and futuristic concept cars, many were also drawn to the wide variety of vision tech on display. The offerings ranged from the latest AR, VR and mixed reality glasses to assistive technologies that enable sight impaired people to navigate their surroundings to therapeutic vision training systems. Here's a sampling of some interesting products VM's lens and tech editor Andrew Karp saw at CES, along with some other products that captured the imagination of show goers.
