The Cylensee PRAR :
Cylensee develops a peripheral retinal augmented reality (PRAR) contact lens, operating as an eye-up display (EUD), by analogy with HUD used in driver assistance systems, allowing the driver to keep their head up and their eyes on the road, while having access to real-time information in their field of view.
Cylensee PRAR embeds an annular lightguide ring with 4 lasers illuminating 8 different holograms projecting icons, warnings or patterns (i.e. few hundred possible combinations) on the parafovea, independently of the eye movements (see below) and blinks.
