The AR coatings are on the glasses as they are AR Anti-Reflection Coating and Premium oil and fingerprint resistant (Oleophobic) as well as are spectra blue light blocking. The AR coatings are very important for scattered light. I see no need to coat them but the extra coatings should not hurt them (at least that’s what the packaging says).
The adjustable strap is works very well and slides in and out with ease; https://www.amazon.com/gp/product/B07GJ2WKG8/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&psc=1
I removed the lens as they were sized for the 3d Printable inserts and glued them in; I had to modify them a bit but after using them for awhile I found I like the strap better as it keeps the lenses tight to my face and away from the Fresnel lens, and when I remove the headset I can see! Plus I have a narrow IPD of 60.5 and I can feel the plastic against my nose even after I did some grinding.
If you look at the packaging information for the “liquid glass”, it does say for glasses as extra protection and it “locks in coatings”. It is very easy to apply; (1) dust off loose dust (2) use cleaning pad to clean the lenses (3) Once completely dry apply the liquid glass in a circular fashion and completely cover the entire lenses. (4) Let dry at least 30 minutes - I let it dry 45 or so. You will see a light haze on the lenses. (5) Use the included microfiber cloth to lightly buff to remove the haze. You will see a nice shiny surface. I would let it complete full setup for a few hours before use.
By the way, our 3D printers are not much different from what would be needed to grind our own lenses - just add polish, spindle, and optical test fixture. I have built something similar before, and have been thinking about a dedicated DIY VR lens grinder…
First off, thank you very much for the detailed posts! They contain everything that I was looking for! Including confirmation that a proper pair of VR glasses will probably outweigh inserts, as far as practicality is concerned. It was a minor pia to have to keep finding my glasses when I was using my Vive with inserts. I’ve been sweating over just how narrow the frames need to be to fit into the headsets: my current glasses do, but just barely: nice to see that you’re using a ‘normal’ pair. Finding something like that shouldn’t be an issue.
Is there a reason why you are looking at frames that actually have the lens frame that goes all the way around? As opposed to the Round glasses that you mention, where the frame only surrounds half the lens.
I’ve been getting my glasses from Walmart: do you think that the optical quality of the Zenni lenses would be appreciably better? So far, I haven’t noticed any issues, but my glasses are usually pretty hammered by the time I replace them, so I probably wouldn’t notice much.
Btw, Croakies are available in a variety of different styles, the one I linked to is the original but it would NOT be suitable for this case. The material is made of a neoprene rubber (think diver’s wetsuit) and it grabs on things(including hair!), we would want one that’s more like what Sidekick1 posted.
I do not notice frames vs less frames personally as the glasses as so close to my face. But that is a personal thing so there are many frames that have no frames around the glasses. I would just recommend that you get as large of lenses as possible to put the edges out as far as possible for your FOV. Light and large! I do own a 5k Plus also and my 8KX has more room inside for glasses BTW. The sliding adjustments for the strap works very smoothly - no hair grab!
Did you go with the ‘Blokz UV and blue light protection’? I would like the blue blocker aspect, but my blue blocker sun glasses turn everything yellow!
Edit: Disregard. I found my answer in your previous post about the “AR” coatings. Thanks!
FYI, after my NanoFixit order fell thru, I tried this product on both my 8KX and the glasses I wear for VR sessions. I can’t perceive much difference, but it certainly didn’t hurt anything and may have indeed helped.
They do add a hardness factor and a bit less light scatter but mainly easier to keep clean. It is not dramatic but I wear glasses so every bit helps . . .
The difference here is the quality of the plastic lenses normally will have small microscopic pits in them. This coating is so thin that what is does is help fill in the pits and gaps allowing a smoother optic, which is always better. Many of the eyepieces and photographic filters I use have muti-coatings to get the right wavelength through. They have to be thin and smooth so there are not any extra blooming reflections on bright stars. So far this very thin layer has made my lenses noticeably smoother and less scatter (reflections).
I know nothing about eye tracking but another optical surface between my glasses and Fresnel lenses would have to be nicely AR coated as each optical surface (front and back) can create a reflection. I don’t need eye tracking personally and am happy with my 8KX view in native resolution and the ability to move my head a bit
