Methods, systems and apparatuses for delivering electrical or other therapy in the vicinity of the eye, comprising eyepieces having a plurality of electrodes that are placed on the eyelid. Some examples are just eyepieces having a periphery that partly surrounds the eye, other examples fully surround the eye or include a temporal portion configured to extend to the temple of the user. Some examples also include a field that covers the eye to take the form of a goggle. Numerous configurations for power supply and therapy output are discussed.

Systems and methods for wireless stimulation of biological tissue (e.g. nerves, muscle tissue, etc.) and, in one exemplary implementation, to therapy for glaucoma based on the wireless administration of energy to the eye of a mammalian subject (e.g. human, rodent, etc.) to reduce an elevated intraocular pressure (IOP) involving the use of a multi-coil wireless power transfer assembly. The multi-coil wireless power transfer assembly may be used alone or in combination with a stimulation coil that can be implanted in the eye of a mammalian subject or within a contact lens worn by a mammalian subject.

A device and method for passing information to a person using cutaneous facial stimulation to generate phosphenes is described. This invention has many uses, but in particular it can be used to transmit visuo-spatial information to a person who is blind or has impaired vision.
