Scientists Have Created Contact Lenses That Zoom When You Blink Twice

By lgentile - August 05, 2019

Do you ever think about how amazing contact lenses are? You may put them on your eyes every single day but have you ever really thought about how cool it is that someone invented these teeny tiny little lenses that are so thin and so small that they can fit on top of your eye and hide just under your eyelid when your eyes are closed? It really is incredible when you think about it! 

They are so thin and light that you can barely feel them in most cases! You can wear them for up to 16 hours and some you can even sleep in, although you may not want to. While contacts still could be more comfortable, they could be easier to put on and could last a little longer, they are still extremely effective and have changed the eye wear game. But now, scientists have invented a type of contacts that are so amazing and so advanced, you won’t even believe that they are a real thing! 



So Freakin' Cool


Have scientists invented contacts that can shoot lasers out of your eyes? No. Not exactly. 

Did they develop the technology for night vision contacts? How about contacts with X-ray vision? While that would be way beyond cool, we are not quite there yet. 

But still, what scientists have invented is so damn cool and so freakin’ unique that you will feel like you need them immediately! 

Blink, Blink


Scientists at the University of California San Diego have developed contact lenses that have the ability to zoom in when you blink twice. 

Come on! How cool is that! You know what this proves, right? It proves that the future is here! 

Hey, future. We welcome you with open arms. We have  been waiting for you! 

Technology Is Awesome!


Shengqiang Cai and his colleagues at the University of California San Diego created a lens that is controlled by your eye movements because technology is awesome! 

The contacts are able to move side to side or up and down, depending on where you look. 

These contacts are like having a tiny little camera lens on top of your eye. You can’t deny that that is cool AF. 

In The Blink Of An Eye


So when you have the contacts in, all you have to do to create your own camera lens is blink twice.

Blink once, blink twice and ZOOM! Better eyesight for everyone just like that! 

And while it seems that with science and technology anything is possible, it takes a whole lot of hard work to achieve an invention like this. It was developed in more than just a blink of an eye. Get it? 

Let Us Explain


The science behind the contact lens is anything but simple but we will explain this kind of science in the easiest way possible. 

Basically, while your eyes may be one of the smaller organs in the body, there’s a lot of electricity behind those little eyes of yours. 

These scientists started by measuring the eye’s natural electric potential. Got that? Okay, let’s go on. 

For The Science Nerds


For you science nerds out there, electrooculography is used to record eye movements during electronystagmographic testing. 

According to Science Direct, “It is based on the corneoretinal potential which is the difference in electrical charge between the cornea and the retina, with the long axis of the eye acting as a dipole….” 

Uh huh. Uh huh. Got that? We hope you are taking notes…

Back To Regular Human Speak


“Movements of the eye relative to the surface electrodes placed around the eye produce an electrical signal that corresponds to eye position.” 

Got that? Should we go back to regular human speak? Yes. No problem. 

They then created a soft lens that responds to that energy. The lens responds differently depending on what signal it receives. 

Ready For Nerd Terms


The contacts are made out of polymers that expand when the eye’s electric current is applied. When these polymers become convex, the lens zooms. 

Hey class, are you still following? Okay great! 

The scientists’ paper abstract breaks it down for you in some more super hard nerd terms that we do not really understand.


Science Is Hard


“In the current work, a novel human–machine interface is developed to use electro oculographic signals generated by eye movements to control the emotions and the change of focal length of a biomimetic soft lens.”

This is why we tried to explain it first in Layman’s terms. Science is hard! 

And for those of you who don’t wear contacts at all, don’t worry. You can still use these lenses. 

All About The Zoom!


If you happen to have 20/20 vision we have some good news for you! If you are not in need of contacts, you can still wear these bad boys once they hit the market. 

You do not need to wear glasses or contacts to sport them at all! 

In the end, these contacts are not about improving your sight. They are all about the zooooooom! 


All I Wanna Do Is Zooma-Zoom-Zoom-Zoom


And scientists do not want to stop there. They have much bigger plans for these special contacts. 

Additionally, in the future, these scientists hope to use these contact lenses for prosthetic eyes, eye-controlled cameras, adjustable glasses, and even remotely operated robotics.

This is all good news for when robots take over and world. Does anyone else have the song “Rump Shaker” in their head? All this zoom zoom talk. 

Welcome, Future.


These contacts prove that the future really is here! And you thought Google Glass was the wave of the future, you were wrong. 

And while you may still need some convincing to wear tiny little robots on your eyes, you can’t deny that this invention is amazing. 

We could all use a little zoom in our lives, couldn’t we? This could be a great tool while tweezing our eyebrows and checking out our pores! 

Great For Driving


These contacts will also be great for driving. Think about all those times you are driving down the street and you can’t read a street sign down the way. 

Well, with these contacts you just have to blink twice and BOOM! Or shall we say, ZOOM! 

With this technology you will be able to read that sign in just a blink of the eye. Or two blinks of the eye, really. 

Here's A Question


Here’s a little question for those scientists over there in San Diego who are working on these special lenses. 

It has been proven that the average person blinks 15-20 times per minute. That’s up to 1,200 times per hour and 28,800 times in a day. 

With all this blinking, will we be zooming all over town? We are sure they have a way around this, but thought we’d ask anyway. 

So What's Next


Alright, so now we have robot contact lenses with zoom in when you blink, so what is next? 

Contacts that make everyone look thinner and younger? That would be cool, right? We vote for that! 

Now, if we can just start working on drones that will go pick up wine and groceries for us, then we are golden. Doesn’t that sound like a great idea?
