That's great, but look at the complexity and size. Wouldn't it actually be cheaper (and more stylish) to just make some normal looking frames and a bunch of cheap interchangeable pre-molded snap-in lenses in maybe 40 different strengths? Let people take their frames and then go through the pile and pick lenses that work the best.

Azlefty: Cthulhu_is_my_homeboy: I know personally, my eyesight didn't degrade until I started using computers heavily during my teen years. As a kid I had razor-sharp eyesight and then it very rapidly deteriorated after I got the interwebs.

I bet you got hairy palms also.

Why do so many humans have poor vision? It seems that natural selection would have weeded them out.
I also wonder, do many animals also have poor vision?


By that logic then we should have weeded out deformities and mental defects, or debilitating inherited conditions. Mutations will always happen and have always happened. I would say more so nowadays we do everything we can to thwart natural selection's work and keep EVERYONE alive and allow everyone to procreate. Also, there are nearsighted and farsighted people, those types of vision would be good in different situations (One for hunting/tracking, and one for gathering), so I wouldn't necessarily say it's bad vision unless you can't see ANYTHING clearly.

As for the second part, dogs have "worse" vision than we do. I believe, by our standards, they are nearsighted. However, they compensate with their other senses, and a greater sensitivity to movement. You also have the difference between prey eye configuration (sides of the head) and predator eye configuration (front of the head) that change the "quality", field of vision, and purpose of their sight.

Mumbler: rustymiller: Why do so many humans have poor vision? It seems that natural selection would have weeded them out. Out of 2 humans, the one with better vision would be able to better spot a predator and escape from it. You can't find your own food without seeing well, etc.

No answer for you, I'd like to know too, though. I don't know how I would have been able to survive at all back then - can barely see 10 feet. I'd be wolf dinner by the time I was 20.


or you would have lived as a member of a tribe, and would have developed skills that were not tied directly to keen vision.

I bet we have had folks with poor eyesight since the start, and I am pretty sure we did not leave them to the cirtters because they had vision issues(Sure nobody wanted to go hunting with that guy, but I bet your tribe would have taken care of ya).

Quite some time ago I read about these glasses in National Geographic in my doctor's office.

/Finally decided to get a monocle after years of wearing glasses and contacts over both eyes. My left eye is almost 20/20, but my right eye needs serious help.

Suck it, haters. This is exactly the sort of thing that will eventually allow people in developing nations to improve their lot. You don't need to spend billions on harebrained schemes (I'm looking at you, OLPC) and public works projects. Glasses, shoes, mosquito netting, anything that allows people to overcome those seemingly minor obstacles that actually have a major impact on one's ability to do anything more than get through the day... it's the little things that have by far the most impact.

KarmicDisaster: Wouldn't it actually be cheaper (and more stylish) to just make some normal looking frames and a bunch of cheap interchangeable pre-molded snap-in lenses in maybe 40 different strengths?

While I take issue with the durability of this product(only time will tell)... what makes it Work is that folks do not need 1 of 40 choices, they need glasses that are exactly what they need, and that is what these do. And, if 3 years down the road your vision changes? do you have to go track down somebody to get a new set of lenses that are "Kind of Close" to what you need?

But lets get to the meat of the issue, Ever worn glasses? How about somebody else's glasses? even if your script is "Pretty Close" your buddies glasses will end up giving you a headache, so Close dose not cut it, that's why this is such a big deal, they are essentially infinitely adjustable.

I would trade functionality for style any day, seems crazy to think style is more important that the glasses working. And you think you can precision grind plastic lenses for cheaper than this guy is making his?

Why don't we have these in the US?

His self-refraction glasses mean people can correct their vision without needing an optometrist.


Would put some optometrists out of business and the average person can save some money.

Perhaps corrective lenses actually lead to increased long-term degradation of eyesight. If this completely baseless supposition is correct, then our ancestors with "poor" vision would not have experienced the same level eyesight degradation that we have today, and would have fared reasonably well.

Or maybe it's just that people who need glasses are smart, so our shortsighted ancestors used their brains to survive :)

Beat me to it. It's called altruism. The members of the tribe with good vision provide for and protect their near/far sighted brethren. In return, the vision impaired work on tasks that are not hampered by their vision problems. Intricate beadwork on clothing, for example, is something that a near sighted person would be well suited for.

I recall the simple explanation of our visual evolutionary history is that our current lifespan is outside specs, so to speak. The odds of any animal living until parts start failing is pretty damn slim, unless they are an apex predator, which we were not until we developed really good stick technology. And even the apex predators get waxed by other predators, more often then not.

The "blind" level of eye issues would of course be pretty much fatal, but that wouldn't really remove the chance of those issues, just make them less common. Completely removing the chance of any genetic trait from our code would require genetic engineering that is far in advance of anything we can do.

ARRRRRGGGHHHH! That misconception is so damn aggravating. The average life expectancy in the past was low because of high infant mortality, not shorter lifespans. If someone managed to live past childhood they had a good chance of living just as long as we do now.

I do wear glasses. And molded lenses, not ground, as I suggested, can be quite accurate, they are used in cameras; they can even cast aspherical glass lenses. The reason that eyeglass lenses are ground is to correct for astigmatism and to create bifocals and because they "can" match exactly. These pump up lenses can't correct astigmatism and aren't bifocal either (although maybe you could let some liquid out for close work, then pump up again). I suggested (say) 40 lenses, which would be enough to get you within a quarter diopter on the common sizes, and then half diopters after that. When the optometrist is flipping between two lenses and you are having a hard time telling which is better that is a quarter diopter generally, nobody would have to settle for a poor fit. I think that the idea that poor people would not like to have stylish glasses for the same cost is just a myth. If all you give them is the Waldo glasses then they will take them, but if given a choice they would take the more stylish pair. Just saying that it could be looked into instead of getting all excited because these have a technical gimmick.

I do have a family member that is involved in collecting, measuring, and distributing used glasses in a third world country.

CapitolG: gund: The guy should win a nobel prize or equivalent.

To start.....

Old news is Old, this was posted like 4 months ago in the Geek tab.

The key to his winning some sort of prize depends on how long the glasses last, if they cannot make it a few years, they are not "That Good" of an idea. or at least... not yet.


Dude, they're 19 bucks to crank out in their current form and they want to drive the unit cost down even lower.

If they last a few years with a replacement cost of 19 bucks -and- are infinitely adjustable during that functional ownership period... win.

I know what my insurance company paid for my last pair of 'nice' glasses... and my out of pocket was 300.

We haven't been subject to that sort of selective pressure in a long time. I'm sure that if you examined chimps, that they'd have more uniformly good vision than we Homo sapiens, since chimps really do need to beware of the leopards.

Hell, you do not even have to send a box of them, just one set of glasses.... that and i am pretty sure theese folks could give a daym about "Stylish" Glasses, they are likely happy as hell to see well.

I can imagine these glasses being handed out through UN relief programs. They aren't cheap (now) but with a few design changes and enough mass production (think lots of 100,000) they can be made for a lot less, possibly as little as 3 dollars a pair.
 
2009-09-17 05:41:24 PM
Cthulhu_is_my_homeboy: I think much of it is modern society. Sure there were always people with bad eyesight (who were taken care of by the rest of the tribe if they had other redeeming qualities), but now we spend so much of our lives focused intently on objects that are much closer to our faces than our ancestors evolved to deal with--books, computer screens, restaurant menus. Visual acuity means so much more to us than it did to our ancestors. Even somebody with 20/40 vision can spot the lion-shaped blob of color moving toward him, but it takes a modern lifestyle to make resolution of fine details important.

I am not sure I understand your logic. By the time a person with bad vision recognizes that the 'blob' is lion shaped, he isn't likely to do any more procreating.

You might take a little longer to figure out what that blur is on your computer screen, but it is not likely to result in your immediate death, and if you get fired, you can always be a bartender. Its not sexy, but it is better than being eaten.

Okay, I'm no inventor, but it seems to me this could be done a bit more elegantly....

Put a piston in each temple. The pistons can be screwed in to push more of the fluid into the lenses, or screwed out to reduce the amount of fluid in the lenses.

It seems to me this would also reduce the problem the gradual loss of fluid over time. You wouldn't have to keep refilling the glasses, you'd just screw the pistons in further until they were all the way in. Only then would you need to refill the lenses.
