A new technololgy developed by Eli Peli, an ophthalmologist and bioengineer at Harvard Medical School in Boston, augments the vision of those having tunnel vision with images captured by a small video camera mounted on special glasses. The lenses have a transparent video display mounted on them that superimposes imagery captured with the video camera and renders outlines of objects missing from the users field of view. Read all about this new technology in the NewScientistTech article entitled ‘Augmented reality’ glasses tackle tunnel vision.
