It's just an onsite lab at the local optical shop. It's privately owned and they ship their lenses out to be coated. Just ask around to local places and tell them you need three things: A CR-39 lens or Trivex (better quality but more expensive), an Anti-reflective coating on the inside and outside of the lens, a solid silver mirror on the inside of the lens, and for the lens itself to be dyed as red as they possibly can.
