Mojo Lens smart contact lenses will soon be on sale. They have a gyroscope, microLED and a battery right on the eye

Augmented reality (AR) in any helmet or goggles is an interesting vision, but the question remains how many people would voluntarily walk down the street in something similar. At least in the current state of technology.

Mojo Vision has been doing this differently for years and has opted for microLED display technology integrated into the contact lens. It should be noted that there have been more such ideas in the past and Alphabet and his medical daughter Verily flirted with the idea. But so far, it has only ended up on paper or in very early prototypes as an idea that simply cannot be reliably produced.

Small LCD right on the eye

But year by year, Mojo Lens smart contact lenses are approaching the goal and especially the construction that some daredevil would actually put in his eye. The latest version of the prototype, which was discussed by colleagues from the IEEE Spectrum and who were able to test it with their own eyes, already contains their own microbattery.

So how does it work? The contact lens contains a simple monochrome microLED 14,000 pixel display 5GHz radio transmitter for connection to the main unit, tiny battery with medical specification and unit IMU (accelerometer, gyroscope, magnetometer), which is used, among other things, to monitor eye movement. The movement of the eye is used to navigate the menu with applications.

Since lenses are envisaged for each eye, they can then create using stereoscopy three-dimensional perception. The last technology that remains to be implemented is optical sensor – basically a form of simple camera.

For patients and athletes

And what good will it do? Similar lenses could play a medical assistive role – for example, they could have poorer eyesight highlight edges, which is a relatively simple computational problem. However, some demo applications tested by journalists from the IEEE Spectrum also promise a real AR experience. Maybe navigation assistant, display route and heart rate data for athletes and so on.

The main obstacle, however, will be the psychological block and health aspects. Not every passer-by will probably want to put on contact lenses armed with a pile of electronics. Despite the fact that particularly hard lenses, unlike soft ones, suffer from drying of the eye surface, its irritation and generally poorer tolerance for more sensitive people.
