When we go through the history of research on 'bionic eye', some progress in to availing more information about the visual perceptions can be seen recently
.
The researchers shall get satisfactory results, (thus helping millions of persons having visual impairments) by getting fundamental principles of sensory perception.
In the wakeful state sensory areas in the brain viz, visual, auditory , olfactory ectc.. are naturally stimulated by the electro magnetic waves reached there from spinal code and other parts of Central Nervous System. These EM waves are absorbed from atmosphere through certain parts of CNS (As explained in the earlier articles.) In normal persons the sound or sight are converted in to signals at certain parts of sensory organs. These signals travel in to the concerned sensory areas in brain-thus changing the frequency and wave length of EM waves present there in wakeful state. These changes in the frequency wave length of EM waves are analyzed in the concerned part of brain- giving sensory perceptions. (In the sensory areas of brain of persons in deep sleep there shall be no EM waves.)
If the researchers get more understanding about these phenomena better results are possible in fields such as bionic vision
