An improved method and subconjunctival device for causing the eye to focus on a near object. The device automatically changes the focal length of the eye in response to a changing of the length of the medial rectus muscle or the inferior rectus muscle so that the eye can focus on a near object. The device is powered by a rechargeable battery and includes an electrode for stimulating the ciliary muscle as the length of the medial rectus muscle or the inferior rectus muscle changes.
