At a dollar each pair (from the full article), he could sell them in the developed world at a massive profit, then use the money to subsidize spreading them through the developing world. Even if they're not as attractive or usable as glass lens (and the article doesn't suggest that at all) they'd be disposable. $20 for glasses I don't have to worry about losing? I'd buy a pair.

  $20 glasses? What about $8 glasses ordered online and shipped from Hong Kong? A friend of mine got these and they're definitely cheaper-feeling than your typical $130 pair, but at 8 bucks a pop, you can get a whole bunch and you're bound to like one of 'em: http://zennioptical.com http://zennioptical.com (I'm not affiliated with them in anyway... just another near-sighted person happy about cheap glasses)

    Good point. Ok, then $4 a pair. Gonna go look for my prescription so I can buy some $8 glasses now, thanks.

  Weird. I was routinely buying glass lenses in India at $10. Now I am in Canada and I pay $150 or more for similar lenses.

  There is no country in the world where a dollar is not affordable. From the countries I know: 1$ in China = 2 Packs of Cigarettes or 3 bowls of noodles 1$ in Africa = 2 Meals of Rice or 2 trips on a motorcycle Why subsidize something that is so cheap? It's pointless and counterproductive. Treat other countries not like aid recipients, but like real people who can be traded with, and are happy to get cheap stuff just like you are.

      I'm not saying you don't have a point, but the last time that I bought a pair of glasses, the whole affair—getting the prescription, and the frames, and the lenses—cost well over one day's salary for me. I'm sure that even for someone making just 75¢ a day, $1 for a pair of glasses would be considered a bargain if it means the difference in being able to see.

        Several years ago my prescription glasses broke, so I replaced them with cheap non-prescription glasses for about five bucks. They weren't quite as good (I have astigmatism) but they were serviceable. Only recenlty did I get another pair of prescription glasses specifically for computer use. I spent several hundred doillars (even after insurance discounts) and they are not significantly better than the el cheapo ones I have been using. Yes, there is value in getting regular eye exams, but non-prescription cheap glasses work just fine for lots of people (and mine won't get filled with algae after a few weeks).

  I know of a company that is adopting this exact business model to distribute vaccines around the world.
  - markessien 18y ago
    Out of curiousity, vaccines for what illnesses?
    - daniel-cussen 18y ago
      Malaria, polio, and a few others, I think.
      - markessien 18y ago
        Malaria has no effective vaccine. Polio only exists in 3rd world countries at the moment, so it's doubtful it's sold in the first world to subsidize the 3rd world. If a company is claiming to do this, they are very likely to be scammers.
        daniel-cussen 18y ago
        I have my facts wrong, then. I don't know which vaccines they are working on, but I imagine they are ones that are commonly given out. The company has not, to my knowledge, claimed to have a vaccine for malaria. Malaria just sounded to me like the kind of disease they'd try to fight.

It seems the tooling/tech required to make cheap glasses has been around for a while (see link below), however is the ability for the end user to adjust his prescription really advantageous in the long run? Will they evaporate easily in warmer climates, etc.. http://web.mit.edu/newsoffice/2002/eyeglasses-1218.html http://web.mit.edu/newsoffice/2002/eyeglasses-1218.html (also has a TED talk as well IIRC)

If the image in the article is the actual prototype, the glasses looks pretty big and the lens seems really thick, therefore: I think this is simply great because it will help mainstream the "nerds with big glasses" stereotype. Also, when you are outside and in the sun and you need a pair of shades, just pour some coffee into your glasses.

This was news at least 5 years ago. Since my optometrist travels to Nicaragua every year to help people with their eye problems, I asked him about these glasses. He wasn't so interested because there are plenty of free glasses available here that people donate and which they take with them. Here's the "news" from 2002: http://query.nytimes.com/gst/fullpage.html?res=9D07E0DF163AF933A25751C1A9649C8B63&n=Top/News/Health/Diseases,%20Conditions,%20and%20Health%20Topics/Eyeglasses&scp=1&sq=josh%20silver%20eyeglasses&st=cse http://query.nytimes.com/gst/fullpage.html?res=9D07E0DF163AF...

Ive bought cheap (under $%) non-prescription reading glasses at a local drug store. If they retail for five bucks, the wholesale cost is probably half that, and the cost to produce half again. Why not sell those to the developing countries? At least regular glasses won't fog up with algae in a short time. It's a clever idea making water-filled glasses, but how practical is it really?
- debt 18y ago
  These glasses have adjustable lenses that could fill most prescriptions. Also, $1 for a pair of glasses isn't affordable in the developing world. I would assume the wholesale price of the water-lensed glasses is way below $1.
