Abstract

An eyeglass is provided for component weight without reducing the overall structural integrity of the eyeglass, and for allowing adjustability of the eyeglass to optimize optical and protective qualities during activities having differing head angles and primary lines of sight. The eyeglass can comprise a lens, a frame, and a nosepiece. The frame can have opposing terminals and an upper groove extending at least partially along the frame and a downwardly extending post. The nosepiece can have a mounting component extending upwardly to engage the post, and the lens can be cooperatively retained between the frame and the nosepiece. Sets of corresponding nose pieces and lenses are provided, to optimize the eyeglasses for different primary viewing axes in the vertical plane.

Claims

1. An eyeglass for minimizing component weight without reducing the overall structural integrity of the eyeglass, the eyeglass comprising:

a unitary lens having an upper edge and a lower edge, the upper edge having lateral connectors formed at opposing ends thereof, the lower edge having a nosepiece opening formed therein;

a frame having opposing terminals and an upper groove extending at least partially along the frame, the upper groove being sized and configured to receive the upper edge of the lens with the lateral connectors of the lens being receivable into the opposing terminals of the frame, the upper groove having a cross-sectional area defined by a depth and width of the upper groove, the frame further having a post extending downwardly from a central portion of the frame; and

a nosepiece having a bridge and a mounting component extending upwardly from the bridge, the nosepiece having a lower groove extending at least partially across the bridge, the lower groove being sized and configured with the lower edge of the lens being receivable therein, the mounting component being attachable to the post for attaching the nosepiece to the frame;

wherein cooperative engagement of the frame to the nosepiece is operative to retain the lens therebetween for minimizing the cross-section of the upper groove without compromising overall lens retention and the overall structural integrity of the eyeglass.

2. The eyeglass of claim 1 wherein the cross-sectional area of the upper groove is approximately less than 0.02 square inches.

3. The eyeglass of claim 1 wherein a maximum thickness of the frame is less than 90% of a thickness of the lens along the upper edge thereof.

4. The eyeglass of claim 1 wherein the post comprises a connecting portion at a distal end thereof, and the mounting component comprises a recess being sized and configured to receive at least the connecting portion of the post for attaching the nosepiece to the frame.

5. The eyeglass of claim 1 wherein the post connects to the frame posteriorly to the groove.

6. The eyeglass of claim 1 wherein the post is integrally formed with the frame.

7. The eyeglass of claim 1 wherein the recess of the mounting component is formed into a posterior side of the mounting component.

8. The eyeglass of claim 1 wherein an as-molded configuration of the lens corresponds to the upper groove of the frame and the lower groove of the nosepiece.

9. The eyeglass of claim 1 wherein the lens is configured to be mounted anterior to the post and the mounting component of the nosepiece.

10. An adjustable eyeglass for optimizing a vertical viewing angle of a wearer during a heads-down activity, comprising:

a unitary lens having an upper edge and a lower edge and defining the optical centerline;

a frame having an upper lens receiving portion and a post, the upper lens receiving portion extending at least partially along the frame, the post extending downwardly from a central portion of the frame, the post being integrally formed with the frame; and

a nosepiece having a bridge and a mounting component extending upwardly from the bridge, the nosepiece having a lower groove extending at least partially across the bridge, the lower groove being sized and configured with the lower edge of the lens being receivable therein, the mounting component being attachable to the post for attaching the nosepiece to the frame and for supporting the lens between the nosepiece and the frame, the mounting component having a vertical height, the vertical height of the nosepiece being customizable for optimizing the vertical viewing angle of the wearer.

11. The eyeglass of claim 10 wherein the nosepiece is selected from a plurality of nosepieces having different vertical heights.

12. The eyeglass of claim 11 wherein a selected nosepiece is interchangeable with another selected nosepiece.

13. The eyeglass of claim 10 wherein the nosepiece further comprises a nose pad and a collar portion, the nose pad being formed along a bottom portion of the bridge, the collar portion being formed along the bridge and extending intermediate the lower groove of the bridge and the nose pad.

14. The eyeglass of claim 13 wherein the collar portion varies in size relative to the vertical height of the mounting component.

15. The eyeglass of claim 10 wherein the post comprises a connecting portion at a distal end thereof, and the mounting component comprises a recess being sized and configured to receive at least the connecting portion of the post for attaching the nosepiece to the frame.

16. The eyeglass of claim 15 wherein the recess of the mounting component is formed into a posterior side of the mounting component.

17. The eyeglass of claim 10 wherein the post extends downwardly from a central portion of the frame posterior to the lens receiving portion of the frame.

18. An adjustable eyeglass system for optimizing optical characteristics of the eyeglass along a line of sight of a wearer, the eyeglass comprising:

at least a first and a second unitary lenses having an upper edge and a lower edge, each lens defining an optical centerline;

a frame having an upper groove and a post, the upper groove extending at least partially along the frame, the post extending downwardly from a central portion of the frame, the post being integrally formed with the frame; and

at leas a first and a second nosepiece having a bridge and a mounting component extending upwardly from the bridge, the mounting component being attachable to the post for attaching the nosepiece to the frame and for cooperatively retaining the lens between the nosepiece and the frame, the mounting components having a first and a second vertical height;

wherein removing the first nose piece and first lens and mounting the second nose piece and second lens to the frame moves the optical centerline from a first angle to a second angle with respect to a straight ahead line of sight, and changes the height of the lens in the vertical relative to the wearer'"'"'s straight ahead line of sight.

19. The eyeglass of claim 18 wherein the second lens has a greater vertical height above the nose piece opening than the first lens.

20. The eyeglass of claim 18 wherein the nosepieces are selected from a plurality of nosepieces having different vertical heights, the selected nosepiece being interchangeable with another selected nosepiece.
