Microcurrent Stimulation is a painless, non-invasive treatment that uses  small barely perceptible impulses of square-wave direct current at low voltages, delivered through electrodes in contact with the skin overlying key nerves around the eye. This current is applied to key points around the eyes, helping to increase blood flow to the macula, the portion of the retina affected by macular degeneration. 

This treatment is adapted from a FDA  approved therapy used to treat other disorders.  In preliminary studies by the Macular Degeneration Foundation this treatment has improved both visual acuity and color perception.
