From their Design section, which has real designers blogging on topics in their field, is Will Smart Contact Lenses Be the Bluetooth Headsets of the Future? Stuart Karten of SKD opines on solar powered lenses with LED information displays (University of Washington) or his idea of ‘assisted living’ lenses which give food calorie counts or the GPS for the nearest gym. Other than the ‘creep factor’ for many of putting a foreign object in the eye, Ed. Donna (who lost that at age 15 with her first pair of corrective lenses) muses on some other factors…distraction worse than the head down-sidewalk strut of the smartphone-addicted, corneal abrasions (as one ages the eye dries out) and competition with the floaters that one gets as the years pile on.
