1. An electrostimulation device for treating dry eye, comprising:
(i) an electrode system comprising one or more electrodes wherein (a) a portion of said one or more electrodes intended to be applied in contact with the eye, the eye orbit, the temple, the eyelid areas or a part of them, respectively imitates the surface shape of the eye, the eye orbit, the temple, the eyelid areas or a part of them or wherein (b) a portion of said one or more electrodes intended to be applied in contact with the eye, the eye orbit, the temple, the eyelid areas or a part of them is flexible and adaptable in its shape in such a way that in the cases (a) and (b) a form-fit coupling is achievable between said portion of said one or more electrodes and the surface shape of the eye, the eye orbit, the temple, the eyelid areas or a part of them, wherein said portion of said one or more electrodes intended to be applied in contact with the eye, the eye orbit, the temple, the eyelid areas or a part of them is fed or feedable with an electromagnetic wave of distorted sinusoidal current with a resonance frequency, which includes the related harmonics; and
(ii) a radiofrequency circuit suitable to emit an electromagnetic wave of distorted sinusoidal current with a resonance frequency which includes the related harmonics, in which the electromagnetic wave of distorted sinusoidal current feeds said one or more electrodes, and in particular said portion of said one or more electrodes intended to be applied in contact with the eye, the eye orbit, the temple, the eyelid areas or a part of them, wherein said portion of said one or more electrodes extends to cover the eye, the eye orbit and the eyelid areas of the eye, wherein said portion in its extension involves most of the meibomian glands and of the lacrimal glands.
