It is a kind of for preventing the imagination of the Ocular irritation ciliary body of presbyopia and glaucoma, to determine that its contraction is submitted train of pulse in the period by low voltage direct current and formed. This contraction, if being applied to rhythmic way frequency, object ciliary muscle and passive gymnastics improve its convergent force, size and efficiency. The raising of this power moves crystal with higher efficiency, and therefore improves its regulating power. Similarly, the formation of the contraction stretching tendon of ciliary muscle restores the natural function of girder, and thus preventing glaucoma directly with the distance between the trabeculate increase lamella of sclero-corneal sclero-corneal angle. Stimulation anatomic region corresponding ciliary body is located at corneal limbus suitable distance when occurring by using conductive electrode directly to be contacted with bulbar conjunctiva. The contact lense comprising 4 electrodes is described, the electrode in two is facilitated to contact and operator is facilitated to work.
