Scientists Have Created a Futuristic Contact Lens That Lets You Zoom In By Blinking

Futuristic dystopian game Cyberpunk 2077 isn’t even out yet, and scientists are already bringing the future of body enhancements to our world. University of California’s scientists have developed a robotic soft contact lens that allows you to zoom your view by blinking twice. That is cool.

“Eye movements like blinking carry change potential to signal. Shengqiang Cai, the lead researcher, told the New Scientist that the eye has an electro-oculographic potential, even if you’re sleeping:

Even if your eye cannot see anything, many people can still move their eyeball and generate this electro-oculographic signal.” (The Next Web)

They used these signals as ways to control the device, with the signals changing the focal length of the lens. Furthermore, due to the soft nature of the lens materials, focal length changes can reach up to 32 percent! This movement does deform the lens, and that make me question the health of people’s eyes who’re wearing them – at the end of the day, it’s a small piece of plastic, and it’s rubbing against your eye as it moves. Healthy? I’m not confident, though I’m sure if these were made publicly available such issues would have been ironed out.

The creators believe this technology will be used in visual prostheses, adjustable glasses, and even remotely controlled robotics later down the line. If you had zoomable contact lenses, what would be the first thing you did with them? Order from the specials board across the restaurant? Watch TV from the other side of your house?
