Imagine wearing contact lenses that allowed you to zoom in on far-off scenes, have useful facts pop into their field of view, or create virtual crosshairs. Researchers at the University of Washington are working on imprinting an electronic circuit and lights at macroscopic scales onto flexible, biologically safe contact lenses that should allow the wearer to see a virtual display.
Practical applications range from helping vision-impaired people to see better, holographic driving control panels and even as a way to surf the Web on the go.
And, might we add, replace the traditional LCD and/or viewfinder on a digital camera.
“Looking through a completed lens, you would see what the display is generating superimposed on the world outside,” said Babak Parviz, a UW assistant professor of electrical engineering.
