[T]he days of popping reading glasses on and off or constantly shifting your gaze through bifocals may be numbered. Researchers at the University of Utah have developed "smart glasses" with liquid lenses that can automatically adjust their focus.
"The major advantage of these smart eyeglasses is that once a person puts them on, the objects in front of the person always show clear, no matter at what distance the object is," says Carlos Mastrangelo, the electrical and computer engineering professor who led the research along with doctoral student Nazmul Hasan.
[...] The new smart glasses consist of lenses made of glycerin, a thick clear liquid, enclosed in flexible membranes. The membranes can be mechanically moved back and forth, changing the curvature of the glycerin lens. The lenses are set in frames containing a distance meter on the bridge, which measures the distance from the wearer's face to nearby objects using infrared light. The meter then sends a signal to adjust the curve of the lens. This adjustment can happen quickly, letting the user focus from one object to another in 14 milliseconds.
The glasses come with a smartphone app, which uses data about the wearer's eyeglass prescription to automatically calibrate the lenses via Bluetooth. When the wearer gets a new prescription, they can simply update the information on the app.

Finding a decent doctor is tough. Until I found this one doctor I was just consigned to having crap glasses. Then one day I got an awesome set.
My last dude got mine wrong. My eyes were getting better until I got my current pair. Now everything is blurry without them. I only got them because the old pair was coming apart.
The dude was amazing. Everyone I knew who wanted or had them went to that doctor. He was that good. His kid who I got this set from? Not nearly as good and misdiagnosed my eye condition. His father was the only one who got it right.

Same here.
In my case, the daughter, called in her dad, and he finally got it right after she had two successive prescriptions made that were crap.
Old Guys Rule.
I've learned to always have the Eye Doc provide the first set, even if its more expensive than Lenses-Are-US. Get the sunglasses there, and the computer prescription there, but get the doc to provide the first set.
No, you are mistaken. I've always had this sig.

when you 'chance' upon the right prescription, have the optometrist make a copy of it for you...
(they SHOULD be gracious about it, but some are dicks, but they should give it to you, dicks or no...)
you can do two things with that,
1. take to new optometrist if you move/whatever and (presumably) get the same good glasses...
2. send off for cheap online glasses when these get lost/break/whatever...
as an aside, as a four eyes since 2nd grade, the fit of the glasses can REALLY make a lot of difference in if you can focus well in your field of view... *particularly* the wire rimmed and other types with the nosepads on a little arm, those are easy enough to get knocked out of alignment and affect your fit and focus greatly... if you are handy, you can maybe get them bent back into shape, but it is easy enough to break them off, too... (thus taped nosepieces, etc... yeah baby, nerd chic !) most eyeglass places you buy from will re-adjust your frames/nosepads for free while you wait...

That's not been my experience, but maybe I was just lucky. I never had a problem with any eye doctor I ever visited, and I was extremely nearsighted from before age 7 when I was first tested until I had a CrystaLens implanted in my left eye at age 54.
My sight in the eye that had surgery is better than 20/20 now. My ex-wife wasn;t so lucky. She had a different surgeon put implants her eyes, now she wears bifocals.
If the glasses suck, find a new doctor. There are a lot of good ones out there.
