Scientists invent zoomable contact lenses

Researchers have developed a contact lens that can zoom in and out in response to certain eye movements.
The idea of being able to zoom in to a distant object using just your eyes has been explored in science fiction for years, but now a team at the University of California San Diego has actually managed to turn this concept into a reality thanks to a new type of robotic contact lens.

The technology works by detecting and responding to the "electro-oculographic signal" of the eye.

"Even if your eye cannot see anything, many people can still move their eyeball and generate this electro-oculographic signal," said lead researcher Shengqiang Cai.

The team hopes that the technology could also lead to the development of a robotic bionic eye.

"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 researchers wrote.

I'd really like to know how this could work without something physically moving in and out (like a zoom lens) on your eye. I mean, if it functions like an actual zoom lens, how could it work when placed on an eye like a contact lens? I could see a zoom lens implant, or zooming eye glasses, but not something that is worn like a contact lens...Unless its travel is less than 1mm...

Imagine having technical difficulties with something like this? "ARGH! I can't zoom out!?!? WHY?!" "HELP, I'm stuck between zooms! EVERYTHING'S BLURRY!! "

I assume it's more along the lines of adjusting the bend/thickness of the contact lenses in order to replicate some slight zooming capabilities. I'm not sure how it's been implemented but I'm somewhat doubtful of the effectiveness of the 'zoom'. Will have to find out more about these in future and see what kind of progress is made.

My interpretation is that it would enable you to go from near sight to long distance, rather than acting like binoculars. But what do I know!

https://www.iflscience.com/technology/this-robotic-lens-enables-users-to-zoom-in-on-objects-just-by-blinking/ This article explains (somewhat) how the lens works. Pretty cool, actually. Although not capable of telephoto level zooming.
