Abstract
An eye alignment assembly for aligning a tool with a user. The eye alignment assembly is mounted to the tool. The eye alignment assembly includes a sight point of an optical fiber positioned a distance behind an alignment indicia on a lens. An adjustment system is provided to reposition the sight point of the optical fiber relative to the alignment indicia on the lens. The eye alignment assembly provides an indication of orientation of the user relative to the tool in at least two degrees of freedom.

An eye alignment assembly for aligning a tool with a user, the eye alignment assembly comprising:
- an eye alignment assembly mounted to the tool, the eye alignment assembly comprising a sight point of an optical fiber positioned a distance behind an alignment indicia on a lens;
- and
- an adjustment system adapted to reposition the sight point of the optical fiber relative to the alignment indicia on the lens, the eye alignment assembly providing an indication of orientation of the user relative to the tool in at least two degrees of freedom.
A alignment system comprising:
- a tool;
- an eye alignment assembly mounted to the tool, the eye alignment assembly comprising a sight point of an optical fiber positioned a distance behind an alignment indicia on a lens;
- and
- an adjustment system adapted to reposition the sight point of the optical fiber relative to the alignment indicia on the lens, the eye alignment assembly providing an indication of orientation of the user relative to the tool in at least two degrees of freedom.
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.
