Augmented reality contact lenses could soon replace our phone screen


Contact lenses could soon replace the screens of our phones. However, augmented reality – where glasses or contact lenses display information about the environment around us so we can see the real and virtual worlds simultaneously – will be the most significant development.

Multitasking is an activity people love to do (but inefficiently in many contexts). Phones will look like tiny servers running all these devices as we wear more electronics on our bodies, including headphones, watches and soon glasses, the latest advancement in invisibility. computing.

In an ordinary office building in Saratoga, California, several engineers are working to make this idea a reality, as reported by Bloomberg. Each week they create prototypes of a smart contact lens that contains one of the smallest screens, tiny circuitry and batteries.

The lenses developed by Mojo Vision are a technical feat and one of the most ambitious hardware projects in Silicon Valley today. The company had to develop its own chemical and plastic components in order to allow an eyeball to breathe through an electronic lens.

The lenses are unmistakably thick and large enough to partially obscure the outer whites of the eye. It’s not uncomfortable, according to the startup’s senior director of product management, David Hobbs, who has ported several prototypes.

A flexible circuit no wider than a strand of hair and nine pacemaker-style titanium batteries are used in the lens to provide all power and data. The pixels, which are squeezed into a space of just two microns, or 0.002 millimeters, are amplified using a mirror with a slight convexity that works similar to a telescope by reflecting light onto a tiny reflector. . From a distance of a few meters, this small spectacle looks like a point of light.
