It remains somewhat speculative, to be sure. But a group of researchers has made advances towards a Terminator-like era of augmented vision. Researchers at the University of Washington in Seattle recently established that their “bionic contact lenses,” which could someday stream text and images right in front of their wearer’s eyeballs, are “safe and feasible,” reports BBC News. Safety tests in rabbits have shown no ill effects, meaning research will continue. How would such a device work? After all, it’s difficult to focus on something held too close to your nose, let alone something projected directly on your eye. The researchers, led by Professor Babak Parviz, have already solved this problem, in collaboration with researchers at Aalto University in Finland. By adapting the lenses to shorten the focal distance, your eyes don’t have to strain to focus on something impossibly close. “You won’t necessarily have to shift your focus to see the image generated by the contact lens,” Parviz explained to New Scientist.
