AR smart contact lens lets wearer see the world in a whole new way

A US start-up has designed a smart contact lens for everyday use which delivers an augmented reality (AR) display in a user’s field of vision.

The AR contact lens offers a display with information and notifications. It also allows the user to interact by focusing on certain points and is operated by eye movements. Developed by California-based Mojo Vision, the company has so far raised over $100m £77m for the project.

“Mojo has a vision for invisible computing where you have the information you want when you want it and are not bombarded or distracted by data when you don’t,” said chief executive Drew Perkins.

Mojo Vision’s idea is to reduce our reliance on phone and tablet screens by putting it on our eye. This means users who get a message won’t have to pull their phone out of their pocket or bag to read it, but rather look into the corner of their vision to make the message appear and read it then and there.

The company added that the lens is also connected to the internet, meaning users can get almost instant access to information based on their surroundings – for example, the way to the nearest restaurant or supermarket.



During a demonstration, company executives showed how the contact lens could enable users to see a virtual teleprompter, navigation instructions or other interactions that appear floating in the field of vision by projecting a micro-LED display to the retina.

A user, wearing two lenses which may be fitted with a correction prescription, could ‘click’ by concentrating on an icon – to launch a music player, for example – and turn it off by looking away or blinking.

“We want to create a technology that lets you be you, lets you look like you; it doesn’t change your appearance, it doesn’t make you act weird walking down the street,” said Mike Wiemer, co-founder and chief technology officer at Mojo Vision. “It’s very discreet and frankly, substantially, most of the time it doesn’t show you anything.”

By putting an AR display in the lens, the company would be scaling down modern immersive hardware, which often means strapping on neck-straining headsets.

“Today’s AR headsets are too awkward to be worn in social and professional situations and many AR solutions try to create immersive experiences that can clutter reality,” the company said on its website. “That’s why Mojo has pioneered the concept of ‘invisible computing’ – a display that never gets in the way.”

Mojo Lens uses unique, purpose-built microelectronics and the world’s densest microdisplay, which reportedly has a resolution of 14,000 pixels-per-inch. According to Wired, which has tested the device, the prototype lens has an embedded display about the size of a dot from an ink pen.

If the user is looking straight ahead while they’re wearing the lens, they won’t see anything unusual. However, users just need to move their eye to any corner of their range of vision to activate a pop-up screen with icons for notifications, weather calendar and music. They can also expand these icons further to see more details by staring at an arrow next to them.
