What is "NIIRA"?

With NIIRA from Eyesynth you will be able to perceive by sound waves what the white cane or the dog does not allow: Aerial obstacles. Branches, awnings or elevated elements will be perceived up to five meters in advance.

Users can move around without bumping into objects because NIIRA's sound waves tell them exactly where they are. This makes it easier to walk on the street or locate objects in a
3-dimensional space.

Using a bone conduction audio system, the ears of visually challenged or blind people remain free. This allows them to hear everyday auditory messages as well. ​

With a bone conduction audio system. The audio is transmitted through the skull, reaching the cochlear nerve. In this way, the ear is free to hear the rest of everyday sounds.

And, just like that, we eliminate hearing stress, as we don’t use the eardrum to listen to NIIRA.

Innovative solution

Thanks to NIIRA glasses, I experience a freedom to move around that I no longer thought possible. The impact on my life is indescribable.
