Sensor system for determining the control signals activating ciliary muscles

A sensor system for determining control signals of a ciliary muscle (10) of an eye (5) having a cornea (6), a lens (7) a pupil (9), an iris (8), ciliary muscles (10), Müller muscles (11), Brück muscles (12) and zenular fibers (13), the sensor system comprising:

• a) a contact element (16) consisting of an electrically non-conductive material for disposition on the cornea (6) in contact with the area of the eye around the iris (8) thereof,
• b) a sensor system with at least one sensor (17) applied to the contact element (18) in an annular array around the iris, and
• c) a signal processing arrangement (39) disposed on, or in, the contact element (16),
• d) each sensor (17) comprising at least three electrodes (1, 2) oriented in the same direction (4) and arranged in a row,
• e) the orientations comprising at least one orientation in a radial direction with respect to the iris (8) and
• f) each sensor having an intermediate electrode (1) which forms a reference potential and two electrodes (2) which are disposed in the orientation direction directly adjacent and at opposite sides of the intermediate electrode (1) and which determines an eye body potential with respect to the reference potential.
