That you wear for prescription glasses? Unlikely. Glass cannot be shaped into aspheres without very expensive grinding and polishing techniques. Multiple glass shapes are typically molded together to make an aspheric lens. The challenge is that molding the lens this way decreases the Abbe number significantly, which is why it’s not used for prescription eye glasses. If you have astigmatism, your lenses are most likely a polymer of some sort. Check with your optometrist.
I wear contact lenses and I would buy one of these without prescription glass in them. Not to use as glasses, but for the value-add. Adding features to the outdated design of the human body is a net positive as far as I'm concerned.
While not a lens shaped from ice there are people who have been working on lenses made from untraditional materials. For example here is a guy, Prof. Joshua Silver's, who has been working on eyeglasses for the developing world. From https://www.medicalnewstoday.com/articles/302550.php:
> Each lens is made of two flexible membranes that move either inward or outward depending on the amount of fluid - a silicone solution - they contain.
> The lenses are connected to a small syringe that sits on each arm of the glasses, and the wearer can adjust a dial on the syringe to pump fluid in or out of each lens. When fluid is pumped in, the power of the lens is increased - correcting hyperopia, or farsightedness - while pumping fluid out decreases lens power, correcting nearsightedness.
What about people who wear prescription glasses, but can't wear or dislike contact lenses? Is it possible to replace the lenses with prescription ones?
Check out the "what it does" page towards the bottom under the headline "evolutionary design" it shows a picture of a lens mounted on a pair I assume you could get a prescription lens if you wore glasses.
Someone's already made glasses whose lenses are membranes filled with mineral oil or something similar. They can be "focused" with a screwdriver (adjusting circumference, ergo pressure and convexity, or some such) -- and, of course, each lens can be adjusted separately.
They are also, per the articles I saw, cheap to make. Not necessarily a fashion statement, but supposedly quite functional. If they are for read and exist in production -- some of these "good idea" articles are just that.
Additionally, the glasses come with multiple nose pads that’ll be helpful for extended use and a prescription frame if you need it.
Would it be feasible to build slim adjustable optics that could allow anyone to set their prescription dynamically and directly within the glasses or would that make the glasses too bulky or hideous looking?
Also, it would probably be possible to use lenses in the glasses with a certain dioptre strength applied, so that people could use those instead of their regular glasses.
Has anyone here who wears glasses tried prescription blue-light-filtering lenses? I can't really use the orange glasses lots of people recommend in the evenings because they don't fit well over my glasses--even the clip-ons I bought don't sit right. I've read a bit about prescription lenses that filter blue light, but haven't tried it. I'm curious if anyone else has an what their experience was like.
The officially suggested way is to put prescription lenses in a GGlass "frame" and some of the publicly seen GGlass usages have been with such frames/lenses.
Some amount of aberration is inevitable in spectacle lenses, because you're severely constrained in terms of weight and thickness. Most people don't want to wear glass lenses for safety reasons (they're legally prohibited in many jurisdictions), which further constrains the options available. There just aren't many variables to play with.
Smaller lenses will reduce how noticeable abberation is, but if you have a high prescription then I'd strongly recommend going for contact lenses.
Not 'eventually', it's already confirmed, manufactured and used - some of the demoed Glass units have a slightly different front frame where prescription lenses can be attached in the same way as for "normal" glass frames.
