Abstract

Ergonomic eyeglass frames are particularly suited to surgical, medical and dental applications. A set of eyeglass frames having a temple portion and lenses arranged in a plane, whereby the angle between the temple portion and the lens plane defines a pantascoptic angle. A pair of surgical telescopes or loupes are mounted through a lower portion of one of the respective eyeglass frames, with the pantascoptic angle preferably being 80 degrees or less to provide a more stable physical mounting of the telescope or loupe through the lower portion of each lens element.

Claims

1. Ergonomic eyeglass frames particularly suited to surgical, medical and dental applications, comprising:

a set of eyeglass frames having a temple portion and lenses arranged in a plane, whereby the angle between the temple portion and the lens plane defines a pantascoptic angle;

a pair of surgical telescopes or loupes, each having an optical axis and being supported by one of the respective eyeglass lenses; and

wherein the pantascoptic angle is less than 80 degrees and the angle formed by the optical axes of the telescopes or loupes and the plane of the lenses is substantially 90 degrees.
