A device for forming artificial vision by electrical stimulation includes: an image acquisition unit (1) used to acquire an image; a signal conversion unit (2) used to convert the image acquired by the image acquisition unit (1) into an electrical stimulation signal; a signal transmission unit (3) used to send the electrical stimulation signal on to an electrical stimulation array (4); and the electrical stimulation array (4) used to electrically stimulate a cornea, a sclera and/or an eyelid in contact with the electrical stimulation array (4) by using the electrical stimulation signal so as to form an electrical stimulation image on the cornea, the sclera and/or the eyelid. The device buries or attaches a flexible electrode array into or on to a contact lens, a user can perceive the electrical stimulation image on the cornea by directly wearing the contact lens, and the artificial vision is formed. |
