Landmark Hearing Aid via 3D Printing and Earlens Corp

California-based Earlens Corporation have introduced a newer variety of hearing aid that uses light to enhance hearing. Similar to contact lens, the lens attaches to eardrum through surface tension. The device consists of three parts: a light tip, a custom-fitted lens and a photon processor which transmits sound waves to the light tip, which converts the sound into non-visible light.
