In-eye tests begin for first AR-based smart contact lens

Mojo Vision CEO Drew Perkins announced last week that he became the first and currently only person to wear the latest prototype of Mojo Lens, an augmented reality-based contact lens.

The world’s first augmented reality (AR) contact lens is one step closer to being accessible to everyday wearers.

Mojo Vision announced earlier this year launching its latest prototype for the Mojo Lens.

The smart contact lens features updates such as a micro-LED display and medical-grade micro batteries, as well as new hardware and technologies embedded directly into the lens, including eye tracking, communications and software.

More recently, CEO Drew Perkins shared in a company blog post on June 28 that he received the “first demonstration on the eye” of the lens itself. Since he is currently the first and only person to wear the lens, he has done so with only one lens at a time, for one hour at a time.

Originally launched in 2020, the fully self-contained Mojo lens prototype features the following industry-first technologies, Perkins wrote:

  • a 14,000 pixel-per-inch MicroLED display with a diameter of > 0.5 mm and a pixel pitch of 1.8 microns (the world’s smallest, densest display ever made for dynamic content);
  • custom application-specific integrated (ASIC) design with a 5 GHz radio and ARM Core M0 processor that allows sensor data to be sent from the lens and AR content to be streamed to the MicroLED display;
  • custom-configured accelerometer, gyroscope, and magnetometer that provides continuous eye movement tracking, keeping AR images still while the eyes move;
  • a patented energy management system consisting of medical-grade micro-batteries and an internally developed power management integrated circuit;
  • an intuitive eye-tracking interface that allows a user to access content and select items without hand or gesture based controllers – just natural eye movements.

The current prototype requires a user to wear the ARM processor around their neck so information can be wirelessly relayed to the lens and back to computers that track eye movements, as well as a hat with an integrated antenna for enhanced connectivity.

While testing with one lens in one eye, the company’s next goal is for two lenses to work as a pair, allowing a wearer to see in 3D (similar to virtual reality and AR).

In a recent interview, Perkins said other company executives will try the hardware next. However, the early stages are focused on making the hardware work simply. “We spent a lot of time validating and calibrating the radio to make sure the radio works,” he said in the interview with CNET. “We’re not doing long-term tests yet. We’ll get there.”

The latest developments and ongoing testing are part of Mojo Vision’s ultimate goal, Perkins says, to submit the lens to the FDA for market approval.

“To achieve this, we will conduct several clinical studies to test its capabilities and provide feedback on software and apps,” he stated in the June 28 blog post.
