American Optical is no longer a company, and sadly not even an internet search indicates that they ever were. Fortunately though, many of their original products live on through the name and manufacturing trademarks of other companies. The AO Phoropter is one of them. In 1967 American Optical released the ‘Rx Master’ which has since become the world’s most used manual refractor. It exists today–slightly modified under ownership of Reichert whom since those days has slightly changed the materials used internally to be lighter and slightly easier to turn, switch, and maneuver. Besides these basically-unoticable revisions, the AO is today’s Ultramatic Phoroptor; blindfold yourself and see if you can tell the difference (hint: you probably can’t). That isn’t necessarily a bad thing though- the Reichert (being the original patented device) should be the best- and for the most part it is. The dials are without doubt the smoothest on the market, and if you’re prone to arthritis you’ll appreciate the easy-turn of dials and knobs. The lenses also appear to have the highest quality AR coating, and when it comes to throwing one off a three-story building, the Reichert breaks but seems to break-less-severe than other models. One thing to note– the America Optical phoropter is much older than other Phoropters Buzz sells- and that shows with shiny black paint and a bit more initial wear.
