    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.

      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.

        A device similar to this already exists Last time I went in to a new optometrist they had a gadget which they had me look into which 'automaticaly' determined my prescription by (I Assume) measuring the distortion experienced by a low power laser shined into my eye. The result was fairly close to my actual prescription and would be quite close enough especially if you didn't have ready access to the miscellaneous additional gadgets required to really fine-tune a prescription. Another note is this, I'll use a nearsighted person with astigmatism for this example, The variables for each eye are: Spherical Abberation: Negative number measured in .25 increments ranging from 0 (no correction) to -8 or more (lots of correction) Astigmatism: Abberation measures in .25 increments ranging from 0 to the amount of spherical correction. Axis: The axis along which the Astigmatism occurs (I don't know what the increment for this is, This one has been constant for me for the past 20 years so I haven't seen much in the way of samples... I do know that 70 degrees and 110 degrees are valid values) Note that I am not an Optometrist, so someone who is more aware should feel free to correct me, but If I make the following assumptions we end up with quite a large problem to be placed on a chart: Spherical: 0 to -8.5 -- 34 possible Astigmatism: 0 to Spherical -- 0 to 34 possible Axis: 0 to 180 degrees in 10 degree steps -- 18 possible lots of combinations spring to mind, I'd say go with the existing automated machines. Possibly combine the marketing for the automated lens fabrication with a program to encourage optometrists to donate their older 'automated prescription baseline devices (or whatever they are officially called'.

        No, not possible. Blurry vision will make a blurry object blurrier. There's a difference between a blurry picture and a picture seen blurrily.

        If what you propose were possible, it would be possible to fix the focus on an out-of-focus picture; after all, a camera with the focus set too close is exactly the same as a near-sighted person.

        You could put a lens in front of the monitor to blur it optically in the right way so that the person with blurry vision would see clearly. Move same lens closer to patient, and it's their glasses. Obviously, we've had this technology for a LONG time...

        It's possible that holographic displays, if they existed in the real world, could do this.

        After all, laser printers used to be incredibly expensive, but they have become inexpensive enough that if someone NEEDS one at home, they CAN afford one. Alternatively, in jet technology has brought down the price to high quality low volume printing at home. The same will happen with 3D printers. Especially, if you think about all of the packing foam and other recycleable materials we throw away right now. It really would be the ultimate in recycling.

      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.

    • If it means that more people who can't afford vision correction can get glasses

      Laser vision correction is only viable for a certain subset of lens-correctable conditions, and isn't a good idea if your vision problem isn't static, i.e. you need a different prescription every couple years. Then there's those who don't feel glasses are so bad that they should risk eye surgery to get rid of them

      "afford" isn't really the issue for most people.

      You are correct, they do have machines that can automatically determine your prescription. However, they aren't 100% accurate. Generally a good optometrist will do that, then also use that as a factor in where to start the "flip the lenses" bit. Since they have a suggestion of where to start, so it goes much faster. But they still do the manual proceedure. If the two agree, great. But relying on the automated one without any sort of "sanity check" on its accuracy isn't a good idea.

      Also I'm not sure the machines work on determining astigmatism.

    To resolve this problem, Griffith has created a prototype device to test the human eye. Patients need only wear the device, which looks like an oversized pair of goggles, and look at the world around them. An electronic sensor superimposed on the goggles monitors the lens in the wearer's eye and adjusts the device's lens to cancel the refractive errors, thus determining the correct prescription.

    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 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?

      Frames are fashionable. Their costs reflect their designer's "genius".

      I know the average geek can't appreciate fashion. And rightly so. But we have to deal with it.

      There are cheap stores with cheap frames but they offer a very small selection.

      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.

      There are only a few fabricators of frames. Like almost every other business, the products are just rebranded. There are different types of frames and some do use more expensive materials. That said, there's a huge markup on frames in "designer" stores.

      Sometimes the lens themselves can be expensive if you have a weird prescription. There are also premiums charged for high-refractive lens (so you avoid the coke-bottle look), scratch resistance, tinting, etc.. These can add $200 to the cost of the lens depen
    • There's the fashion angle, but the frame makers also have a product that people truly need. What am I going to do, not wear glasses? I don't have a choice; I couldn't read the text box I'm typing in without them. It's a seller's market.

      I don't need or want the very latest style, but I do want a pair of glasses that fits, provides a decent field of corrected vision, flatters my face, *and* is comfortable and durable. This runs me a couple hundred bucks, but glasses are something I wear all day every day

      They must not have ghod-awful prescriptions like mine then. The lenses are still the most costly part of my eyeglass purchases.

      That having been said, I have to ask the same question: Why do frames cost so much? I see non-prescription sunglasses at convenience stores -- with frames not too different from what I'd want for daily-wear glasses -- that cost less than US$20. But ju

    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.

      Eye doctors do more than just prescribe eyeglasses. They can also diagnose eye diseases and conditions, and refer patients to more specialized medical treatments. For example, the fact that someone's eyesight is decreasing could be due to blood vessels bursting inside the eye as a result of diabetes. A simple machine that just measures your eyeglass prescription cant check that.

      Comparing this with bloodpressure devices is silly. Any data about a specific measurement of a condition in the body has to be assessed along with other contextual data (other symptoms or lack thereof) to determine if there's a problem.

      So, until you can have a machine that can read all possible physical data outputs from a person's body, and analyse in real time all possible medical problems based on those measurements, I doubt doctors of any field will become obsolete.

    Get your mod points ready...

    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 poor need help, and this guy is giving them help, which many people don't do. Seriously, how hard is this to understand?

      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.

      Your post sounds more like an excuse to be bitter, even though it doesn't really have much to do with the person in question, or the story. You raise a really good point, but it's not particularly relevant here.

      It's awfully cynical to suggest that "good of humanity" and the slightest wiff of "capitalism" be so diametrically opposed. Abusive capitalism can always be a problem, but as it exists here, there's nothing to suggest that it's the least bit abusive. The business venture side of this project (http:/

      After he receives his patent, you or anyone else will be able to see EXACTLY how this device works. This is how the patent process is supposed to work. In exchange for letting the entire world know about/study his creation he will, for a limited time, have exclusive control over the rights to manufacture it. According to R.K. Dewan & Co. [rkdewan.com] (IP Attorneys) "An inventor has to disclose his/her invention in such a manner that any person, other than the inventor, skilled in the art should be able to work out the invention."

      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 think you may be missing the point. It's good to help people. It's very good to make money by helping people. This is what's called Right Livelihood [beyondthenet.net] in Buddhism. It's one of the components of the Noble Eightfold Path.

      I don't think most Slashdotters have anything against a free market. I certainly don't. What I do object to, however, are business models that rely on distortions of the free market: state-enforced private monopolies in land, raw materials, and information; the externalization of the costs of production (e.g., pollution, paying less than a living wage so that the state is forced to step in to prevent poverty, not paying health care so that the cost of the uninsured is pushed off on the state and on hospitals), the exploitation of workers (as above, but also lockouts, the use of private or state violence to break strikes, company towns, slavery, etc.), and the use of deceptive marketing to avoid the free-market ideal of a fully-informed consumer. All of these things are part of capitalism, but they're not part of a free market. Rather, they are deviations from a free market that benefit the class of people that already own property. For a look at what a real free market would look like, read up on Mutualism [mutualist.org].

      What's good about this story is that the business plan uses a real free-market solution to do well by doing good. Not only should it dramatically reduce the cost of glasses in underserved parts of the world, it will also provide "micro-entrepeneurs" [lowcosteyeglasses.net] in poor areas to make a living while doing so. When done properly, a free market can benefit everyone. However, the non-free market we call corporate capitalism doesn't do this.

    Neal Stephenson's The Diamond Age [amazon.com] 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.

    The best bit of this is the automatic it actually finds the correct lens for you eye.

    At last something can put on your face and a few minutes later have a correct setting for the lens you need.

    I'm sure all the opticians/optomatrists will be sad to loose they jobs (or at least part of the job) to and automated system .But this has got to make to whole process so much easier especially when trying to prescribe lenses for young children or those with communication (eg speach) difficulties.

    The fact it then goes off and quickly makes the lens is purely a plus point in my view.

    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.

    Automatic eye testing has been around for a while. The first units appeared in the 1970s. Today, the technology is quite good. The Canon RK-F10 [canon.com] ("just press start") does a fully automatic "refraction" eye exam. Price is about $7000. This unit is overkill for just fitting glasses; the identical-seeming next model up in the same family ($12,000) collects the data needed for laser eye surgery and contact lens fitting, with all the liability issues that involves. So there's an opportunity for something more compact and at a lower price point.

    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.

Time to take stock. Go home with some office supplies.
