Posted on 09/28/2010 7:28:07 PM PDT by shove_it
For many people past the age of 40, focusing on close objects restaurant menus, for instance just gets harder and harder.
Most people with this condition, called presbyopia, eventually give in and get reading glasses, bifocals or glasses with progressive lenses.
But what if there were another alternative that didn't require people to carry an extra set of glasses or have only part of their field of vision in focus at any one time?
Zoom Focus Eyewear LLC, of Van Nuys, Calif., has just such an option, and with it won this year's Silver Innovation Award. The solution: eyeglasses, called TruFocals, that the wearer can manually adjust to give clear, undistorted vision whether reading a book, working on a computer or looking into the distance.

These are going to make someone a lot of money!!! I want a pair...and I know my husband would like a pair!
Good idea but they are really unattractive.
They’re ugly but so am I. Just so I can quit knocking stuff over and tripping over curbs..
All I need is an ANSI Z87.1 version of these things.
Yes. If you read about them, they need to be round in order to work. It’s definitely function over form. Pretty cool tho.
I thought I saw something like this in a 60’s edition of Popular Science. That one had a pocket of fluid attached to the lens which could be swelled or slimmed by moving fluid into or out of it with a lever, changing the overall focal length. It must have had bad problems like bursting and leaking, or it would have taken the eyewear business by storm.
Great product, if they work as advertised. Do they come in a non-liberal style, instead of the Harry Reid rounds?
If you have both hands full so as not to be able to move the adjustment slider on the glasses, it’s still kind of troublesome.
LOL! You think you’re ugly, well, you haven’t seen me.
Beat me to it! I had to look up the html code for img src. Drats! Haha.
Maybe I can rid myself of these infernal tri-focals.
I think you would find that constantly fiddling with the manual focus adjustment a lot more onerous than just tilting your head slightly (FWIW, I wear tri-focals too). It sounds cute on paper, but I doubt the practicality of it in the real world.
These are just like the glasses that were invented for use in third world countries.
You inject silicon between two flexible plastic lenses, and you change the curve of the lenses.
That’s also why the lens must be round. If they were any other shape, they’d distort when the fluid was injected.
Ohhhh, the Poindexter look.
Actually, these might help me with my fluctuating vision. Hmmm.
What might be nice would be clip-ons that “decorrect” for those aging viewers whose far-vision prescription is too powerful to allow them to read comfortably. If you play a musical instrument while reading from a score, it helps to be able to have the entire field of view in appropriate focus for the score.
If you didn’t look like a Harry Potter wannabe.....
What is needed now is a little chip about the size of a flea that watches your eye and automagically adapts the lenses to whatever your eye seems to be straining to adjust to.
There would, of course, be a version where the hysterisis on the circuit is set wrong, a plane crashes and billion dollar lawsuits occur.
Pretty set path for product development these days. My grandkids won't have to worry about their vision.
So would Barack Obama!
I concur. I have continuously variable focus, with the little hour glass zone. I had lens implants a few years ago due to cataracts, so my farsightedness is absolute. ( Before that I had extreme myopia, so it was quite a change. ) I had bifocals before, and I adjusted instantly to these new glasses, quite literally. I was very pleased from the moment I tried them on, and I would have no interest in any kind of manual adjustment.
BTW, these lens implants are a tremendous boon, as my far vision is very sharp, being limited only by the age of my retinas and a modicum of “floaters”.
If the lens is mechanically adjustable, it should be adjustable by electronic means also.
A circuit could be set up to contantly adjust it for the correct setting to whatever the lens is ‘looking’ at/
Save your money (for just a few more months) for the electro-active lens technology glasses coming from PixelOptics. They’re the real deal. Novel technology. Big players backing them. Automatic or manual switching between near and far vision. Trust me. I’ve seen (with) them. Very impressive.
Hooray! We all get to look like the guy in “Beyond Thunderdome”.
If they’ll cost less than what trifocal high-index lenses with a decent pair of frames will, I’m in.
I’m getting desperate. After a ten-year hiatus from soft torrid lenses, I’m going to give them another try. Eye doc says materials are new, the weights are more accurate, oxygen flow is better, etc. And I could wear them for two weeks.
I won’t do trifocals. No way in hell. And yes, I’m probably being childish. And cheap.
Torrid = toric.
Blasted spell check.
We are in the same boat, if you have astigmatism. People look at me funny when I take off my glasses to read.
Buy my glasses at the Dollar Tree, nothing in there that costs over a dollar.
Oh, a dime store, you mean.
I’m not sure I would like eyeglasses that could tattle about what I’ve been looking at.
Yeah...they are ugly, but I still think they are a good idea....style must be determined by how they can change the lens...
NOW that does look interesting...
Electronic eyeglasses. Oh great! I can surf the web, watch porn, get driving directions, etc., all while knocking stuff over and tripping over curbs.
I work with a guy that has had a pair of these for a while. He likes em, but...I suspect even if they killed him, he wouldn’t say otherwise.
When these are available in cool looking frames with autofocusing lens, I will be on them immediately.
Let me guess: you weren’t the first on your block to connect to the internets. That’s cool.
I’m sure they’ll make better looking ones if they catch on.
I’d definately try them. I have a weird thing with my eyes which is one eye is much more near-sighted than the other, and actually the last time I was told the better eye is now slightly far-sighted.
So I tried the “progessives” and then regular bi-focals, but they just did not work for me.
When I took a class last year that required both book work and looking up at a black board at the front of the room I had to keep switching back and forth between pairs.
These might solve my problems!
Glad they kept working on revising early models. Seven pounds, ouch!
Exactly my thought as to what it will take to make these practical, except that I thought it might make use of the convergence angle of both eyes to calculate distance to focal point and adjust focus accordingly.
Agree....see my response in 44.
I wear progressives, I’m blurred at ALL distances. And the three fields in the progressives is not enough like natural vision. Just had my second cataract surgery 2 weeks ago this Thursday. Hopefully my eye doc can reduce the strength of my glasses when I’m ready for a new RX for them. My reader sits at about 450 now.
I have that problem with computer use, I had my doctor do a pair of RX computer single distance lens glasses, it solved the problem. You can get those as cheap as $30 from Walmart vision centers. They can set your focal length to what you want, they do it for my regular glasses as I do most of my reading and quilting in my lap because of the arthritis in my hands (less strain on my arms and hands).
Oh man, can I get a trial pair of these? They look fabulous!
For the pixel glasses, is a Rx needed or can anyone just buy em and let them work. It looks incredible to me.

**They’ll be prescribed by optometrists just like regular glasses today**
