A new contact lens that works in the same manner as an advanced zoom lens for the human eye has been revealed by scientists. Reports claim users can zoom simply by blinking, or looking around.
The team behind the creation of the new tech come from the University of California San Diego, and unleashed details of it within their new paper inside the journal Advanced Functional Materials, called “A Biomimetic Soft Lens Controlled by Electrooculographic Signal.”
Similar to that of a regular contact lens, the equipment is mounted to the human eye via five electrodes. These electrodes are placed at different spots around the eyeball, and allow for the user to zoom in their view simply by double blinking in quick succession. An electrical charge is applied to the polymer film layers of the lens, expanding or contracting it to change its thickness.
It’s not entirely the first of its kind, given that scientists based in Europe announced a blink-to-zoom 2.8x contact lens back in 2013. The difference is, this new technology is capable of responding to actual eye movements.
By the user looking up, down, etc, the contact lens can be controlled to look in various directions.
It’s early days, meaning it’ll likely be years before the contact lens becomes accessible to the public. The hope, though is that one day it can be used for the likes of visual prostheses and remotely operated robotics.
