Abstract: The invention relates to a device for restoring the accommodating ability of the eye, which comprises: a) at least one optical system (3) b) at least one data acquisition system (8) that does not touch the ciliary muscle and has either acoustic or optical means to detect the movement of the ciliary body, or it has means to detect the spatial orientation of the two eyeballs with respect to each other, or it has means for measuring the diameter of the pupil and the luminance in at least one eye as a physiological control signal for accommodation c) at least one data processing system to produce a regulating signal for the optical system from the physiological control signal received d) at least one power supply system (10), and e) at least one system for attachment (22).
