DEVICE FOR CORRECTING FARSIGHTEDNESS CAPABLE OF COMPLEMENTING THE FARSIGHTEDNESS AND REFRACTIVE ERRORS BY REINFORCING THE ACCOMMODATION ACTION OF THE EYE LENS BY USING A CONTACT LENS MADE OF ELECTRO-ACTIVATED HYDROGEL
PURPOSE: Provided is a device for correcting farsightedness to complement the farsightedness and refractive errors by reinforcing the accommodation action of the eye lens by using a contact lens made of electro-activated hydrogel; to include a controller for controlling the contraction and expansion of the contact lens; and to prevent the farsightedness from speedily progressing when using an existing convex lens. CONSTITUTION: The device for correcting farsightedness comprises a contraction and expansion portion(10) including an optics portion(10-1); a peripheral portion(10-3) and an electrode potion(20) for supplying the contraction and expansion portion with an electrical stimulation; an electric power supply portion for supplying the contraction and expansion portion with the electrical stimulation; and a control portion for generating a control signal to control the electric power supply portion and supplying the same. The contraction and expansion portion(10) is mounted on the cornea to be touched to the cornea, and the electrode portion(20) is attached to the peripheral portion.
