Abstract
An apparatus and method for treating floater problems of the eye. In some embodiments, a magnet is non-invasively held in place against the face, and in particular, over the lower eyelid of the patient over an extended period of time, in order to control the position of the floaters and to stimulate the eye to better focus. In other embodiments, the device is included in eyeglasses that hold the magnet next to the lower eyelid. In some embodiments, the magnet is placed next to the lower eyelid. In some embodiments, the magnet is replaced by or supplemented with electrical stimulation. Some embodiments use a permanent magnet, while others use an AC or DC electromagnet. In some embodiments, a tapping device or heating device is included. The electro-magnetic force, tapping, and/or heat are controlled with a chip, circuit, and/or switch. In some embodiments, the device is placed under the skin.
