The future of Contact lens: Blink digital zoom

     Imagine in the near future, straining your eyes to see something in the distance. Then you blink twice, and, suddenly, your vision zooms in for a clearer view. Blink twice again, and you zoom back out. That sci-fi scenario is closer than you think, based on new research out of the University of California, San Diego, reports the Next Web. 

Researchers there have developed a soft contact lens that is controlled by the wearer's eye movements. Look downโ€” say to focus on words in a bookโ€”and the lenses provide a closer view. Look back up, and they shift back to a more distant view. This is all possible because, in the words of New Scientist, "the human eyeball is electric." The futuristic lens monitors the eyes' electrical signals and responds accordingly.

"Even if your eye cannot see anything, many people can still move their eyeball and generate this electro-oculographic signal," lead researcher Shengqiang Cai tells New Scientist. (The study itself is in Advanced Functional Materials.) 

One big issue is that the current prototype will need a lot of refinementโ€”and miniaturizationโ€”before people can actually use the lenses. For example, test subjects had electrodes placed on the skin near their eyes in order to make the lenses work. 

Still, the potential is huge if a big company invests in R&D. If a huge company ever figured this out, glasses would become so 21st century.
