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.
Rookie
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.
Totally. ;-)
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.
