Consensus seems to be Widmo these days. I bought a vr-lens-lab VR Frame (so the "glasses") not the inserts because I use them at work and at home and the inserts seemed to stupid to always "plug in" and "pull out" for switching the place of usage. It was a bit costly (around 130€ with blue guard coating) but they were delivered in 13 days. Are comfortable to wear and fulfill their purpose. The downside is they make you look quite stupid and they feel a bit flimsy due to the plastic frame. Also the lenses themselves are a bit fragile (compared to my normal glasses) as they scratch rather easy. Aside from that I have no complaints.
I will add, the only downside I can see is that installation/removal is a bit fiddly, not something I'd want to do every time someone else wanted to use my rift. I live alone, so on the few occasions someones wanted to try my rift, its not been a huge deal, but it would be a pain if I lived with family.
