Mojo Vision has introduced a new prototype of its augmented reality and virtual reality (AR/VR) smart contact lens.

Called Mojo Lens, the technology could be used via smartphones, metaverse applications, smart wearables and healthcare. In addition to extended reality features, the smart contact lens includes embedded technology such as display, communications, eye tracking and power system.

The new prototype includes proprietary technologies that were in-house built including a 14,000 pixels per inch MicroLED display that measures less than 0.5 mm in diameter with a pixel-pitch of 1.8 microns. Mojo Vision claims this is the world's smallest and densest display on the market. The display is paired with a micro-optic and custom silicon backplane that can project bright text, graphics and high-resolution video on the user’s retina that are visible both indoors, outdoors or even when the wearer's eyes are closed.

Mojo Vision built a foundational operation system code and user experience components into the prototype for the first-time, allowing users to access timely information quickly and discreetly without forcing users to look down at a screen or lose focus on people or the world around them.

Recently, Mojo Vision signed a partnership with Adidas to collaborate on a hands-free experience and improve athletes’ access to in-the-moment data. The contact lenses can give athletes the ability to focus on workouts or training without the distraction of traditional wearables.

Additional features include:

  • Low latency communication — A custom application specific integrated circuit (ASIC) that uses a 5GHz radio and Arm Core M0 processor for transmitting sensor data from the lens and stream AR content to the MicroLED display.
  • Precise eye tracking — Using a custom-configured accelerometer, gyroscope and magnetometer that continuously tracks eye moments, so the AR/VR imagery is held still as the eyes move.
  • Medical-grade power system — Medical-grade micro-batteries and an in-house developed power management IC and wireless recharging components allow users to wear the contact lens all-day.
  • Eye control — The eye tracking in the Mojo Lens allows for hands-free control over the metaverse and extended reality, allowing users to interact with mixed reality content at a glance.

The next steps

Mojo Vision is seeking partners to explore user testing and analysis of the Mojo Lens. Clinical testing is ongoing, including with users that are visually impaired to allow even those with uncorrectable vision loss the ability to use the smart contact lenses.
