Am I correct to understand that the lens insets for the XReal Air Ultra are different than from the XReal Air 1, and 2 or 2 Pro? If so are there XReal partners that carry those lenses, I used to get mine from VROpticians but they don’t seem to carry anything for the Air 2 let alone the Air 2 Ultra.
I bought my lenses for my Xreal Air 1 from VR-Rock.com . They inadvertently sent me the lenses with inserts for the Xreal Air 2. Excellent customer service. They remade my lenses and sent me the Xreal Air 1 lenses and insert. They provide the new lenses installed in an insert for your XReal Air glasses so you only need to provide your prescription. Fast turnaround time. You could reach out and check with them on the Ultra.
