A Contact Lens that Shows the Blind What They Are Seeing Through Tactile Stimulation


If you thought that the BrainPort was strange, researchers in Israel are now developing a contact lens that would tell the blind what they are seeing through tactile stimulation on their eye. The device uses a smart phone camera to take a picture and than translates that image into a set of electric pulses that the wearer would feel on the eye. The researchers feel like their field testing has been promising, but before this device ever comes to market they have to go through full clinical testing. Tell us what you think of this idea. Would you feel comfortable with having images drawn for you on your eyes? Is this preferable to the BrainPort which uses the tongue?
