Contact lens: You blink and you zoom in

Researchers are in the news this week because of their soft biomimetic lens. Blink twice and you get yourself a closer look at things. Activated soft elastomer works to increase focal length.

Their paper is titled "A Biomimetic Soft Lens Controlled by Electrooculographic Signal, Soft Robotics, in Advanced Functional Materials by Yang Wang, Sheng Xu, Liwu Liu, Jinrong Li .

They described their work in having developed the robotic lens.
================================================
Some years ago when I had cataract surgery, which involves the implantation of intraocular lens (IOLs) rather than contact lenses, my ophthamologist told me that this kind of technology was coming for implanted as well as applied contact lenses: zoom, night vision, microscopy...you name it. Some functions controlled biologically, others through external devices like smart phones.
 
I haven't worn contact lenses in decades but this would be something I'd try. Just yesterday I bought a magnifying lamp so I could see what I was doing with a photograph. These would be much easier to haul around.

The older you get the harder it is to read small print, like the numbers of prescription bottles. I have magnifying glasses around where I need them. But biomimetic contacts that could go from a zoom lens to a magnifying lens would be great.

I am 70 and the older I get the more my eyes get better for small print and putting together miniatures.

But this new development sound like a super cool thing.
 
What happens when....you just have to blink?
 
Sounds cool, but I've always had a fundamental objection to putting foreign objects in my eyes.

But this is a long way from red hot needles.

They should just change it to 3 blinks. Almost noone blinks 3 times on accident.

I've done that when reading certain posters here. Usually with mouth hanging open.
 
Damn dangerous if you're driving on a dusty road with the windows open I think. Other than unintentional engagement, this is very cool. Also interesting that the technology comes so close to the year 2020 (20/20)!

Cheers.

I'm sure. I get enough saw dust and other debris in my eyes routinely. That doesn't work well at all with contact lenses. You eyes become incredibly irritated, your blood pressure goes up, and eventually your head explodes. All of that can be avoided with a simple pair of glasses.

I called over the young guy why was doing weed whacking for our weekly lawn crew. He wasn't wearing eye protection. Those bits of plastic cord can put out an eye when they fly off. He said he knew he should but didn't care. Hope he was on another crew this week because he didn't show up this week on ours. I had called his office. Losing an eye is not something to look forward to.

I agree. I protect my eyes. However, given my interests and pursuits, dust is a fact of that life. Dust always finds it's way in, and the occasional, small wood chip does as well. That precludes contacts as an option for me. Besides, I always have my glasses on - can't see without 'em.
