Scientists at the University of California say they have created smart contact lenses

There are many projects related to new lenses, but today we want to talk about this new project, which is developed by several scientists from the University of California. This consists of new lenses that can be controlled by the movement of the eyes and that would allow us to perform new functions.

These lenses, according to Shengqiang Cai, the project manager, feeds on the electro-oculographic impulses of the eye, signals that are used for this development. According to the details of the investigation, it has been possible to measure the electrical impulses of these movements in order to use them inside the lens. For example, change the focal length of the lens.

It would base the creation of contact lenses in biomimetic soft materials, which is mainly composed of a film of electroactive polymers and with a dielectric elastomer, which would serve to deform the lens and thus achieve changes relative to the focal length.

Through an HMI interface, this mechanism could be activated with several movements of the eye, from moving the eyeball in some direction, to making two blinks to activate or deactivate. One of the most interesting points is that this lens works regardless of whether or not you have a good view, because it is not about helping in this matter, is just to take advantage of the electrical impulses derived from the movement.

The researchers say that this type of development could be useful in various fields such as adjustable lenses, visual prostheses or robotics. However, this project is still in phases of proof concept and there is a long way to see them in the market.
