In a unique invention by the scientists at the University of California San Diego, an amazing soft biomimetic contact lens has been developed by the scientists that are hoped to bring a revolutionary change. As stated by the scientist, the person wearing these contact lenses will be able to have a closer look at the things just on two blinks of the eyes.
As hoped by the scientists, this particular pair of contact lens is expected to bring visible developments in the visual prostheses, adjustable glasses, and even in remotely controlled robotics.
The scientists, while developing this contact lens, are particularly inspired by the ongoing efforts in the area of human-machine interfaces. Henceforth, they are coming up with the polymer-based ‘biomimetic soft lens’ and these can be controlled by an electrooculographic signal.
While developing this particular contact lens, the scientists used the electrooculographic signal to enable different gestures while the eye moves. The best part of the lens is that these are capable of changing focal length based on the signals it receives. As trained by the scientists, the contact lens will zoom in the things caught on its sight on blinking the eyes twice.
The scientists have further explained in their paper, “In this study, we have developed an interface between the human eyes and a soft tunable lens. The EOG signals generated by the eye movements were used to control the movements and the change of focal length of the soft lens. The planar movements or rotations of the lens could be achieved by the actuation of different DE films. The motions and deformation of the soft lens mimicked that of human eyes. Because of the use of soft materials, the relative change of focal length of the lens could be as large as 32% through deformation.”
