1. A method of focused phosphene generation in retinal tissue through deeper intermediate retinal cellular electrical stimulation to the exclusion of direct ganglion cellular electrical stimulation comprising the steps of:

  • positioning at least one stimulating electrode in the vicinity of retinal tissue; and

    applying a long duration stimulation signal to the at least one electrode such that deeper intermediate retinal cells are preferentially stimulated over the retinal ganglion cells and proximal overlying surface axons.
