Bionic Contact Lens May Lead to Overlay Displays

pfman writes "A University of Washington researcher has developed a contact lens including circuitry and a matrix of LEDs. Although not yet a working prototype, this may be a foundation for terminator/robocop style overlay displays in which computer graphics could be superimposed on your normal vision. 'Building the lenses was a challenge because materials that are safe for use in the body, such as the flexible organic materials used in contact lenses, are delicate. Manufacturing electrical circuits, however, involves inorganic materials, scorching temperatures and toxic chemicals. Researchers built the circuits from layers of metal only a few nanometers thick, about one thousandth the width of a human hair, and constructed light-emitting diodes one third of a millimeter across.'" Kotaku notes that this has some obvious gaming implications.

I believe TFA was referring to placing peripheral components such as wireless reception on the part of the lens that is not used by the eye for viewing.

You're confusing two different phenomena. The blind spot from the optic nerve is not in the center of the eye. The reason for the astronomers trick is due to the distribution of rods (brightness receptors) and cones (color rectors) in the eye. There are more cones at the center of the retina, but the more sensitive rods are distributed more peripherally.
