I needed a frame to hold eyeglass prescription lenses or readers for my Oculus Quest 2.. The ones on the web are a bit too pricey with so many lens options. I just wanted something quick and simple. I found a round eyeglass lens, (Eyekepper on Amazon), 43.5mm in diameter and built this lens holder to accommodate. They fit the Oculus Quest 2 and they might just fit the Oculus Quest 1 and Rift ???. The lenses are an easy press fit as well as the fit to the Oculus itself. The lenses pop out of the Eyekepper Readers fairy easy. Any round lens of 43.5mm should work fine. No fasteners or glue necessary. Drop me a note if this adapts to other Oculus headsets.

Here's a link to the $15 Eyekepper 4-Pack Readers on Amazon:

Minimal supports may be necessary to the inside of print. I did print them in TPA with minimal stringing. Works, but a bit too flexible.
