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.
