Google Glass has been hogging the spotlight when it comes to eyewear, but get ready to see new technology designed for those stuck with old-fashioned prescription eyeglasses.About 64% of Americans wear glasses to improve vision. Many can't stand them, complaining that glasses are cumbersome, headache-inducing or don't work in all situations. Meanwhile, the growing amount of time people spend in front of computers and mobile devices has also raised concern about the potential damaging effects on eyesight.That's spurring innovation among eye specialists, who say the glasses industry has been largely stagnant since bifocals were invented by Benjamin Franklin in the 18th century."It's a marketplace with slow technology adoption. There hasn't been new technology in eyeglasses in forever," said Stephen Kurtin, chairman of Superfocus, which makes adjustable-focus glasses that enable wearers to choose the best focus for every distance.
