These are going to make someone a lot of money!!! I want a pair...and I know my husband would like a pair!
All I need is an ANSI Z87.1 version of these things.
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.
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.
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”.
Buy my glasses at the Dollar Tree, nothing in there that costs over a dollar.
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.
Glad they kept working on revising early models. Seven pounds, ouch!
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.
