Maybe too late, but you should try with the Bushnell office directly. Bushnell bought the Bolle brand some years ago and so their local subsidiary is able to help..sometimes. at least better than the retailers or distributors.
i had pbs with the reflective coating of a pair of Bolle 2y ago and they changed a new pair for me. Their office is in Sheung Wan:
