The Mojo Vision Lens (also known as Mojo Lens) was a revolutionary augmented reality smart contact lens prototype developed by Mojo Vision, first publicly demonstrated at CES 2020 and internally tested on human eyes in 2022 before the project was paused in January 2023. Representing the most ambitious attempt to miniaturize AR technology into a contact lens form factor, the Mojo Lens featured a 0.5mm diameter micro-LED display achieving an unprecedented 14,000 pixels per inch with 1.8-micron pixel pitch—the world's smallest and densest dynamic display. The monochrome green display (chosen for optimal human eye sensitivity) provided a 15° field of view projecting directly onto the retina through a miniature reverse Cassegrain telescope, with eye-controlled navigation via built-in accelerometers, gyroscopes, and magnetometers. The lens incorporated an ARM M0 processor, custom GPU, proprietary power management circuit, medical-grade thin-film solid-state micro-battery, and 5GHz ultra-low-latency radio (Bluetooth being too slow) for communication with a separate neck-worn "Relay" companion device handling heavy computation and connectivity. Features included up to 14x zoom capability for vision enhancement. The custom scleral lens design vaulted the cornea for comfortable wear and was being prepared for FDA clinical trials before the company pivoted in January 2023 due to economic conditions, laying off 75% of staff to focus on licensing its micro-LED technology.
