19. A method of aligning a tool with a user, the method comprising the steps of:
-
mounting to the tool an eye alignment assembly including an optical fiber and a lens with an alignment indicia; adjusting a location of the sight point of an optical fiber relative to the alignment indicia on a lens so the sight point appears aligned with the alignment indicia when the tool is in a predetermined orientation relative to the user; and orienting the tool relative to the user prior to use so the sight point is aligned with the alignment indicia. - View Dependent Claims (20, 21, 22, 23)
