Electronic contact lenses have been in development for over a decade by labs around the world. Melding electronics into a contact lens may provide medical capabilities, such as measuring intraocular pressure, analyzing tears for glucose levels, and aiding people with poor vision. Manufacturers and researchers are also striving to develop contact lenses that can offer augmented reality.

The micro-battery powers a light-emitting diode (LED) for several hours, marking the first time that much power was available inside a contact lens. This is superior to the previously used wireless energy transmission, which limits the amount of useful power.

“This first project is part of a larger and very ambitious project aimed at creating a new generation of oculometers linked to the emergence of augmented reality helmets that have given rise to new uses (man-machine interfaces, cognitive load analysis, etc.). This opens up huge markets, while at the same time imposing new constraints on precision and integration.” in a published statement said IMT Atlantique professor Jean-Louis de Bougrenet de la Tocnaye
