Apparently, one of the goals of the technology is to merge the human body with machines to increase people’s abilities or correct certain discomforts that afflict us.
As proof of this, a team of scientists from the University of California, led by Cai Shengqiang, has developed contact lenses capable of zooming in on the user’s blinks.
In the original text of his research, Shengqiang explains that this lens feeds on electrooculographic impulses of the human eye. These impulses are always present, regardless of whether the person is asleep or awake, so they are very useful for this type of development.
The researchers detailed that they used these electrical impulses as triggers of actions on the contact lens, which makes this device capable of changing the focal length.
This new gadget will be made with biomimetic materials, which mimic the characteristics of the common eye.
According to their statements, the main material for the manufacture of these lenses is the dielectric elastomer, which helps the lens change its shape and can achieve the necessary focus changes, which would increase the visual field by up to 32 %. The mechanism will be activated with various eye movements, thanks to the human-machine interface. These movements will include double blinks to activate zoom or change direction to better focus a point.
The lenses are intended to be suitable for the use of any person, whether or not they wear glasses since they are not initially corrective. However, it is not ruled out that in the future they will be used for visual health purposes, such as adjustable glasses, prostheses, robots or other similar devices.
The researchers also stressed that this development can be used in any type of climate and under various conditions. This is because the materials with which they are manufactured will not pose a danger to the integrity of the eye.
While it is still a concept, this innovation has enormous potential that can be exploited in the future for the good of all.
