Dick Baker will recognize this place in an out of the way town near Boston that a hundred years ago was an optical powerhouse.

I remember touring it with my school class in the mid 70's and being given a souvenir of an artificial eye that was rejected for some minor flaw.



Did you know a Lensometer is technically only an American Optical (AO) made device to measure lens power?
