These are prescription lens adapters for your Quest or Quest 2. I haven't tried myself but I assume they should work with the Quest 3S. They are modular and magnetic so that they can be easily removed or swapped if you have multiple users using your Quest 2. The lenses are sourced from a pair of cheap glasses sold by Zenni for $9.95.

Why did I design this?

I wanted a comfortable and modular solution and I couldn't find one on Thingiverse. Either they were modular but were hurting my nose, or they were comfortable but not modular. So I made this so I could have both. And by modular I mean that I need to be able to easily swap the lenses because I have multiple users using my Quest 2. I also found that most other solutions were hard to fit in the headset and very difficult to remove. So I've also designed these to be easy to fit and remove.

For anyone needing to make adjustments I've made this customizable with an OpenSCAD file.

Ordering glasses

As with most solutions I'm using these glasses.

It is recommended that you add Anti-Reflective Coating.

Note! You should enter an IPD of 65mm instead of the one in your prescription.
The IPD will determine where the optical center of the lenses will be positioned.
With the Zenni glasses you have 69 mm between the center of the lenses. So by ordering the glasses with an IPD of 65mm the optical center will end up 2mm closer to the nose on both sides. This will make the optical center of the lenses match up with the optical center of the Quest 2.

Magnets

I'm using 5x2mm magnets that I bought off Amazon

Assembly

1. Put the magnets in the mounts and the adapters. Use a tiny drop of super glue if you want to make sure that they won't pop out when swapping lenses often. Make sure that the orientation of magnets between the mounts and the adapters are correct so that they aren't repelling each other.
2. Important! Before removing the lenses, mark the lenses where the bridge connects with the lens. (See image 3).
3. Remove one lens at a time so that you don't confuse them with each other!
4. Align the markings of the lenses with the notch in the lens adapter and press it in. (It will require some force to get it in.)
5. Put the mounts in the Quest 2. They should snap in place with a little bit of pressure.
6. Place the magnetic adapters on the mounts and you are good to go.
