Cheap Fast Eyeglasses from a Desktop Fabricator
purduephotog writes "Doctoral candidate Saul Griffith of the Massachusetts Institute of Technology and inventor of the Lego powered chocolate printer was awarded the Lemelson-MIT Student Prize for inventing a device that molds eyeglasses rapidly and cheaply. Best of all, he's motivated for the good of humanity."
Griffith's thesis research is actually on "programmable self-assembly, how to make things automatically make things," he said.
:-)
This is the really interesting scientific angle of his work, and based on this, I would say that this small $30k prize is only the beginning for this guy. This approach demonstrates a unique perspective to problem solving that shows how innovative folks like Saul are. But perhaps more importantly for the future of science, science education, and the overall good, he has a social conscience that allowed him to identify a problem that affects people worldwide and has found an innovative solution that does what we all should aspire to do: Make a difference.
And he also makes the rest of us scientists look good.
Good on you Saul.

... Doctor Saul Griffith of the Massachusetts Institute of Technology and inventor of the Lego powered chocolate printer and eyeglass moulder was awarded the Lemelson-MIT Doctoral Prize for inventing a device that cheaply and easily mouldes edible chocolate eyeglasses!
Imagine downloading and printing a new bowl for your food processor, or a new toy for your kid.
Imagine, too, the anguished hand-wringing of corporations over the illegal distribution of copyrighted object designs over the Internet.
Imagine, too, the anguished hand-wringing of governments when the technology reaches a point where you can print parts for an AK-47.
My bet is it's going to be quite the roller-coaster ride when it gets here, and that it's closer than we think...

..."in about an hour?"
I was starting to go blind from looking at all the pron on the internet.
thanks to this man, I will now be able to see better, faster and cheaper!
Hmm, a device that can automatically figure out your prescription, and another that can make cheap eyeglasses?
I see these popping up all over the place, like the "check your blood pressure here" devices.
If it means that more people who can't afford vision correction can get glasses, whether in a poor country or not, I'm all for it.
Happiness is like peeing yourself. Everybody can see it but only you can feel its warmth.
I didn't see this one coming...

I looked into the abyss, and the abyss looked into me--and we both winked.
I could have sworn one optometrist i went to a few years ago had a machine that automatcially brought an image into focus for me. Way cooler than this stone-age notion of looking at the eye chart as the "doctor" flips lenses. Which one is clearer, one or two. Why do we keep doing this stone age crap?
I'm all for automatic vision testing, I feel like my current prescription was issued by a talentless hack.
Automatically testing vision and cranking out lenses is sweet. Next they just need to fire on an AR coating and everyone is good to go.
This sounded like even cooler tech to me. I like the idea of something that takes away the subjectivness of the traditional exam for a prescription. He could even throw a glaucoma tester into the goggles.
"He's lost in a 'floyd hole"
The pr0n is out of focus again. Time to print off some new glasses.
He does it in about 5-10 minutes.

and this folks is what being a real team player is all about, in society where we tell our children that greed and selfishness is bad yet buisnesses teach us the exact opposite , that greed is good and if you are not making 500$ a second profit you are failing, these sorts of things dont come round enough, ask yourself why are you here ? to be a wage slave or to make a real difference to peoples lives

True... to an extent. The 'best' solution involves holding the patent, and letting people use it for humanitarian work for free.

I'm interested in the uses of this machine behind eyeglasses. I've been working on several projects where we are creating instrumentation, and have been surprised to find that optics are both difficult to find in specific diameters and focal lengths, and rather expensive when you do find the optics you need.
While not a big deal to major corporations who don't balk at shelling out $20 a lens for custom work, for academic projects and independant research, that is a significant chunk of the cost of our prototype, considering the ease and realtive low cost involved in obtaining a microcontroller these days.
I imagine that, since he can make eye glasses, producing DCX, PCX, DCV, and PCV lenses would be easy too. I'd love to see this kind of machine available at academic institutions for producing parts for research.

I skimmed the paper, searched for Lego, and as it turns out he's really not uses Legos to power his system. It's merely built out of Legos. I'm disappointed...I thought he developed some sort of fusion generator, a la Back to the Future. Add a flux capacitor and a DeLorean and then I'll really be impressed.
glasses and eyesight used to be one of those really crazy scientific endeavours. how many of use have had huge, unwieldy glasses when we were younger, and trips to the optometrist were like going to some strange laboratory? things like this are fantastic, simplifying the field and making it more accessible to all. i heard about another system developed that can diagnose stimatism by analyzing the red-eye in a photograph. these kinds of scientific endeavours inspire others!
He is patenting the device, and I for one applaud him for letting people use it. Where has our world gone that we call humanitarians fools? Last I checked, "you can't take it with you", and when it comes down to it, with the brains he has, I am sure he will find a job, especially as a Doctoral candidate. I applaud him for thinking of the wellfare of others before thinking of a new sports car like most of america.
I doubt this would destroy a profession. It would take years for this to spread and there is still a need for Opthomologists. This would just make Optimologists a little less employable. This might actually increase eye glass sales. I know that I need a new perscription but I can't afford the $200 or more for even cheap exam, glasses and frames. If they could lower the cost of the exam, glasses and frames. I would mostly likely buy a new pair every year. I might even get a couple different types for different occations.
I hope his next machine makes the frames. The experiences of folks I know who wear glasses (I don't) has been that the lenses are not the biggest cost, it is the frames. Why do frames cost so damn much? I know super cheap frames would be fine for charitable aid to poor people just so they can see but the cost of your average frames, something that strikes me as pretty simple to make, is way too high in the US.
Are frames really that complex and hard to make or is there a lack of competition in the marketplace?

With the right lens, it will.

Mmm.... Recursion...
He would need to invent transparent chocolate first, and if that can not be a billion dollar business, then transparent aluminum most certainly will be.
Wow... could it be that in a few years, traditional eye doctors will become obsolete, replaced by scientists and machine assemblers who never see a patient. I'm taking this from the guy who said he could see these next to the blood pressure machine in wal-mart.
Could this be the writing on the wall for any similar "traditionally" professional occupations. If this is the case for eye doctors, which I'm sure didn't "SEE" this coming, I wonder what's next. Could there be a machine that analyzes your blood and prescribes through a vending machine your prescription?
OR... could I be thinking the insane thinking that many slashdotters and other people do when this type of thing is first invented.
Remember that cars were going to fly long before the year 2000.

Here's his first glasses prototype! Welcome back to the eighties! ;)
But seriously this guy made two wonderfull inventions. They now collect "old" glasses to send to third world but this is a logistics nightmare.
Imagine a simple jeep outfitted with these inventions doing the rounds in poor areas. Put the tester on and voila few minutes later a pair of glasses. 1 day per village. Couple of jeeps. Shouldn't take long at all (after all it is not like glasses need to replaced that often, even in the west once a year is good enough even for still growing kids).
As far as I know it ain't the material that is costly in glasses but the whole distribution process. Plenty of bargain chains around that can offer really really cheap glasses due to scale and not offering specialist lenses. This looks even cheaper for hard to reach areas.
Brilliant.

I "like" how the story posters of slashdot are blinded by these bland phrases like "good of humanity". What exactly does that mean here? Is he giving it away for free? No, but it will be cheap. Is he opening the IP up? No, it's patent pending. In fact he's begining to sound like a (*gasp*) capitalist! And we all know they been knocked around here enough to be demonized. But unsuprisingly when a capitalist helps the poor by helping himself he's a put up on a pedastal as the savior of humanity, but if he helps himself by helping the rich or even just the middle class he's deridded as a scum sucking bottom feeder business man. Why the double standard, slashdot? Why? Is it because the motives seem more pure or somehow more righteous? That perhaps, because poor people get the short end of the stick all over the world that they don't just need help, but somehow deserve it too? That we are compelled to serve them? And when we don't feel compelled by this directive we've somehow failed at an obvious yet never stated goal of life?
What this guy has done is great, not because it will help poor people but because he's been extremely clever. I hope he makes an assload of money. Of course once he does make a reasonable sum, some people will complain that his motives aren't pure anymore. One can only hope they can synthesize becoming rich and helping poor people in the same thought.
The next remark is false. The previous remark is true.
In more upbeat stores frames are closer to designer clothing. You pay because the costs of designing a new model is only spread over a few models. Ford Focus costs less then say the latest ferrari and that ain't just the cost of manufacturing.
But yes for those in need a single frame design in a couple of sizes (for different size heads) is not that expensive. Just ask any army that used to issue soldiers with glasses. Or for that matter look at the cost of sunglasses.

He is sued by the people who makes the eyeglasses today?
And you think printer cartridges are expensive now!
Usually, there is no interest in finding solutions for the world's poor - because the profit margins are vanishingly small compared to selling things to the world's middle and upper classes.
This guy is great because, while he will be trying to make some money (guy's gotta eat, you know), he engineered a solution for a problem everyone overlooked because despite the potential for improving a great number of people's quality of life, the potential profit margin was too low.
Personally, I think he needs to package this system up and sell it and supplies to the four-eyed with money first. I'd like to be able to print out new lenses whenever I wanted, and if his process really is so much better, it would be cheaper than buying every couple of years from my optometrist.
Neal Stephenson's The Diamond Age was a good fiction book on the effects of a society where people have their own personal matter reconstruction equipment. Those with the cheap units are subjected to lives full of cheap commodity throwaway (but completley recyclable!) things, while those with more money for the better equipment can have better, higher quality things. And those able to afford real hand-made objects seem to hold themselves above all that.
"Beware of he who would deny you access to information, for in his heart, he dreams himself your master."
Not "opening the IP up" would be manufacturing a "black box" that creates eyeglasses that cannot be opened or studied in any way, at least not without the lawyers/hit squad coming after you. The inventor would still have exclusive control over the rights to manufacture it, but no other person would be able to study it in any way.

I have wondered if it were possible to make a program that could help determine the shape of the corrective lens needed for a vision defect.
Since with high resolution monitors and 256 (or more)levels of gray available, it should be possible to create an 'eye chart' that looks bleary and out-of-focus to a normally-sighted person but sharp and clearly-focused to someone with deformed vision.
I imagine a program where the user can adjust the software implementations (precise changes on the screen regards to the blurring of the chart characters that mimic the effect of an individual lens) of the various corrective lens stages of an eye exam. When the user is seeing clear and focused characters on the eye chart, the program would know from the distortions of the normal chart needed to create this clarity exactly what the eyeware prescription would need to be for this individual user.
The user could send the eyeglass perscription to a off-shore eyeware maker and get perscription glasses made at a tiny fraction of inflated American prices. Or order the glasses made by the method developed by the subject of this article.
If you read about the history of eyeglasses, you'll learn that back in the middle ages, when what we, today, call "proper" eyeglasses (not just a simple magnifier, but a lens that corrects for nearsightedness or farsightedness) - were invented, in Venice Italy, their fabrication was a carefully guarded trade secret. Corrective eyeglasses were for the extremely wealthy only. Among the extremely wealthy, of course, were the keepers of this secret.
Think about the millions of people who were functionally blind, and could not afford glasses due to this trade secret.
And now - due to openness of the technique, and this new technology, optical health insurance (and the incredibly obnoxious markups on lenses and frames that came with it) may no longer be necessary. Let's hope so.

No pun intended.
I have keratoconus (basically a deformity in the cornea) and some days I can see fine and some days things are a little blury. The only solutions are either rigid contact lenses (ick) or cornea replacement surgery (double ick). Glasses aren't much of a solution for me because my eyes shift so much that a prescription would maybe last a month or two at most.
Maybe with this device I could cheaply fab lenses that would work for me until my eyes morph again. And then all I'd need to do is fab another pair.
I have trouble with passwords among other things.
It's too bad the original article doesn't say anything about how he makes lenses.
The current trick in low-cost eyeglass distribution for the third world is simply to use a kit of low-cost preformed round plastic lenses. Basic eyeglasses have a spherical component, a cylindrical component, and an axis for the cylindrical component. The lenses are round, and can snap into the frames at different rotations, the number of different lenses needed goes down to a hundred or so. And the whole kit fits in a briefcase.
