Scientists have launched a new form of automated contact lens that is controlled by diminutive movements of the eye.
That means that users can use blinking – and variations of blinks – to cause the lens on command to zoom in and out. They suppose that this breakthrough may one day lead to the creation of eye-controlled cameras, or prosthetic eyes even. A typical contact lens is structured from salt water only and functions by copying the human eyeballs’ natural electrical signals. This lens is just a tad special. The head of this special study, Dr Shenggiang Cai, informed local reporters: “Even if your eye cannot see anything, many people can still move their eyeball and generate this electrooculographic signal.” To form the lens, they gathered special polymers that broaden when an electrical current is implemented. Five electrodes envelop the eye and perform like they were muscles. As the polymer enlarges to become more indented, the lens zooms in.
Dr Cai added: “The system developed in the current study has the potential to be used in visual prostheses, adjustable glasses, and remotely operated robotics in the future.” While this is all very intriguing, we don’t know still when the robotic lenses are coming to the market, or what they’re going to cost. Though, Dr Cai persisted: “The system developed in the current study has the potential to be used in visual prostheses, adjustable glasses, and remotely operated robotics in the future.” The horizons are limitless.
