Glasses like these put the screen at a focal distance further than a monitor, closer to TV distance. Optics wise it’s basically the same as VR, if a VR headset is easier to try.

If your corrected vision needs stuff 6” away, don’t expect AR or VR to be a solution with current optics

The pair I have (original xReal Air) include a glass insert that can be ground to your prescription. It's a thin piece of glass, I don't know exactly what kind of prescription can be put onto them, but it might be helpful.

That is usually for very low prescriptions. Judging by the photos, I don't think you can use those blanks for much more than -2.

some AR glasses come with built in correction up to -5.00. Beyond that, they recommend correction lens insert, so it can work for more. The built-in correction does not do astigmatism, that will require prescription insert too.

I'm around -6 and was able to get an insert for my VR headset. There are third parties who partner with eyeglass lens manufacturers to make them for most headsets.

possibly this is rather a template to cut a.preacription lens to the right size, just like glasses come with templates for the prescription lenses. the prescription lenses are shipped in a large round shape, and then cut to match the template.

This is what I've been worried about. I have lens implants so I already have a fixed focus as well. The combination of the two would likely be a problem.

In a VR headset the virtual screen distance is set by the distance of the microdisplay from the lens in the headset.

It's not crazy to think you could move the microdisplay position and get a virtual display at 6". There might be other optical consequences (aberrations, change in viewable area) but in principle it can work.

The microdisplays are usually fixed in place (and sometimes the display and optics are a single package), so it would likely be a bespoke solution.

I'd be open to trying something like this. It might be the kind of simple solution that would work for me.

a few AR glasses come with adjustable knobs for nearsighted people. So, not all of them are fixed distance.

You can get a free trial of an Apple Vision Pro at an Apple Store.

Even if you have absolutely no intention of ever buying one it would give you a free and easy way to find out if a headset type device would work well with your vision or just be totally incompatible.

Some ar glasses support adjustable focus, and others support custom prescription lenses.

I just returned the Virtue Pro. I got custom lenses too. The edge/corners were still blurry. With custom lenses I would have preferred fixed focal.
