     DESCRIPTION OF THE PREFERRED EMBODIMENT 
     With reference now to the drawings, and in particular to FIGS. 1-6 thereof, a new pair of visor sunglasses embodying the principles and concepts of the present invention and generally designated by the reference numeral 10 will be described. 
     More specifically, it will be noted that the visor sunglasses 10 according to the present invention comprise a frame 12 having a first ear piece 14 pivotally mounted thereto and a second ear piece 16 pivotally mounted such that the frame 12 can be engaged to respectively opposed ears of an individual wearing the device 10. A lens 18 is removably mounted to the frame 12 by a lens coupling means 20. The lens 18 engages a nose of the wearer so as to support the frame 12 above the eyes of a wearer. A visor 22 is mounted to the frame 12 by a visor coupling means 24 and projects outwardly from the frame 12 so as to reduce glare into the eyes of the wearer. 
     As best illustrated in FIGS. 2 through 4, the frame 12 according to the present invention 10 comprises an elongated center portion 26 having a first lateral portion 28 projecting from a first end thereof, and a second lateral portion 30 projecting from a second end thereof. The first ear piece 14 is pivotally mounted to a distal end of the first lateral portion 28, with the second ear piece 16 being similarly pivotally mounted to the distal end of the second lateral portion 30. By this structure, the first ear piece 14 and the second ear piece 16 can be flatly folded into a substantially parallel orientation relative to the center portion 26 of the frame 12 for storage of the device 10. 
     With continuing reference to FIGS. 2 through 4, it can be shown that the lens coupling means 20 according to the present invention 10 comprises an unlabelled first lateral tab projecting from a first side of the lens 18 and a second lateral tab 32 projecting from a second side of the lens 18. The lateral tabs are substantially similar in design and configuration, and therefore only the second lateral tab 32 will be described in detail. The lens coupling means 20 further includes securing projections 34 extending from the lateral portions 28 of the frame 12. The securing projections 34, as best illustrated in FIG. 3, are configured so as to extend through unlabelled apertures in the lateral tabs 32. Preferably, the securing projection 34 and the aperture through the lateral tab are cooperatively configured so as to define a substantially rectangular shape which precludes pivoting of the lens 18 relative to the frame 12. By this structure, the lens 18 can be simply snapped into securement with the frame 12 as shown in FIG. 1. 
     Referring now to FIG. 4, it can be shown that the lens coupling means 20 according to the present invention 10 further comprises an alignment projection 36 extending from the center portion 26 of the frame 12 which is received through an unlabelled aperture extending through the lens 18 so as to align the lens 18 relative to the frame 12. By this structure, the lens coupling means 20 ensures proper alignment of the lens 18 relative to the frame 12 during coupling of the lens 18 thereto. 
     Referring now to FIGS. 5 and 6, it can be shown that the visor coupling means 24 of the present invention 10 comprises a plurality of mounting pegs 38 extending from the frame 12 and projecting through unlabelled apertures in the visor 22. Preferably, a plurality of the mounting pegs 38 project from the center portion 26 of the frame 12, with a further plurality of mounting pegs 38 projecting from the lateral portions 28 and 30 thereof. The mounting pegs 38 can simply be frictionally engaged to interior surfaces of the apertures within the visor 22 through which they project so as to removably couple the visor 22 relative to the frame 12. However, and as shown in FIG. 6, the mounting pegs 38 can be shaped so as to define a flattened head 40 facilitating permanent securement of the visor 22 to the frame 12 if so desired. In this connection, the frame 12 is desirably molded from a thermoplastic material, wherein the mounting pegs 38 are integrally formed therewith such that the mounting pegs once positioned through the apertures and the visor 22, can be heated and deformed so as to define the flattened head 40 securing the visor 22 permanently to the frame 12. 
     In use, the visor sunglasses 10 according to the present invention can be easily utilized to shield glare from above a user&#39;s eyes and further to filter light passing through the lens 18 prior to admittance of such light into the eyes of the wearer. The removable coupling between the lens 18 and the frame 12, and between the visor 22 and the frame 12 if so desired, limits the device 10 to be selectively constructed and deconstructed for storage and/or travelling purposes. Further, it is within the intent and purview of the present invention to provide a plurality of disparate lenses 18 which can be interchangeably coupled to the frame 12, as well as a plurality of disparate visors 22 which can also be interchangeably coupled to the frame 12 as desired. 
     As to a further discussion of the manner of usage and operation of the present invention, the same should be apparent from the above description. Accordingly, no further discussion relating to the manner of usage and operation will be provided. 
     With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of the invention, to include variations in size, materials, shape, form, function and manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by the present invention. 
     Therefore, the foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the invention.
