This is an older style minus cylinder American Optical (AO) phoropter (model 11320). It was purchased as a spare but never used and no longer needed. It appears to work fine, and my minimal testing found the prescriptions to be accurate.
This is a used and completely functional Nikon autorefractor unit. Completely refurbished several months ago and only lightly used since. We are upgrading to an auto refractor with auto K, so we don't need it anymore.
