American Scientists create contact lens that zooms

This lens prototype reacts to the electrical stimuli that are generated with the natural movement of the eyes and allows the user to zoom in on what they see


A group of scientists at the University of San Diego in California created a contact lens that allows users to zoom in with a simple blink of an eye. This prototype is made with polymers and responds to electrical signals generated by the natural movement of the eyes.

This study was originally published in Advanced Functional Materials during the month of July and explains in detail the importance of electroculographic signals for the control of this biomimetic lens.

To New Scientist, Shengqiang Cai, one of the researchers responsible for the project, said that "even if the eye can not see anything, many people can move their eyes and generate electroculographic signs", explaining that humans can emit these Signs even when they're asleep.

However, Gizmodo states that this prototype is not yet ready and only works under very special conditions, as the individuals who were subjected to tests had to put a series of electrodes around the ocular area. The same publication states that in the near future scientists hope to be able to use this adjustable prosthesis in glasses and for possible experiments in the area of robotics.
