However, in an alternate embodiment, the sun glare shield  10  includes perforations that permit the user  24  to see through the sun glare shield  10  while at the same time keeping the sun glare  14  from entering the vehicle  12 . 
   As discussed hereinabove with specific reference to  FIG. 1 , the vehicle  12  has the driver side fold down visor  16  attached to the vehicle  12  above the top  64  of the windshield  52  on the driver&#39;s side of the vehicle  12 . The passenger side fold down visor  18  is attached to the vehicle  12  above the top  64  of the windshield  52  on the passenger&#39;s side of the vehicle  12 . The rear view mirror  20  is attached via the rear view mirror mount  22 , described hereinafter with specific reference to  FIG. 6 , to the windshield  52  proximate to the top  64  of the windshield  52 . The rear view mirror  20  is centrally located between the driver side fold down visor  16  and the passenger side fold down visor  18 . The sides of the rear view mirror  20  are not flush against the sides of the driver side fold down visor  16  and the passenger side fold down visor  18 . 
   The sun glare shield  10  is attached to the windshield  52  by an attachment device  26 . The attachment device  26  include but are not limited to static electricity, suction cups, adhesive tape and hook and loop tape. The sun glare shield  10  is positioned on the windshield  52  so that the top side  32  of the shield  10  is flush against the top  64  of the windshield  52  and the front side  36  faces the interior of the vehicle  12 . The sun glare shield  10  is also positioned on the windshield  52  so that the space on the windshield  52  between the driver side fold down visor  16  and the rear view mirror  20 , when the driver side fold down visor  16  is in the folded down position, is covered by the sun glare shield  10 ; the space on the windshield  52  between the passenger side fold down visor  18  and the rear view mirror  20 , when the passenger side fold down visor  18  is in the folded down position, is covered by the sun glare shield  10 ; the space on the windshield  52  between the rear view mirror  20  and the top  64  of the windshield is covered by the sun glare shield  10 ; and the space on the windshield  52  below the rear view mirror  20  and between the driver side  16  and passenger side  18  fold down visor is covered by the sun glare shield  10 . 
   Herein, the user  24  is driving the vehicle  12 . Both the driver side  16  and the passenger side  18  fold down visors are in the folded down position. The sun glare shield  10  is attached to the windshield  52  so that the windshield  52  between the driver side  16  and the passenger side  18  fold down visors is not visible to the user  24 , while at the same time allowing the user  24  to continue using the rear view mirror  20 . The blocked windshield  52  prevents unwanted sun glare from entering the vehicle and impeding the user&#39;s  24  line of vision thereby causing dangerous driving conditions. 
     FIG. 3  is an illustrative view of the sun glare shield  10  of the present invention in use. The sun glare shield  10  includes the left  28 , right  30 , top  32 , bottom  34 , front  36  and back side  38 . As discussed hereinabove with specific reference to  FIG. 1 , the vehicle  12  has the driver side fold down visor  16  attached to the vehicle  12  above the top  64  of the windshield  52  on the driver&#39;s side of the vehicle  12 . The passenger side fold down visor  18  is attached to the vehicle  12  above the top  64  of the windshield  52  on the passenger&#39;s side of the vehicle  12 . The rear view mirror  20  is attached via the rear view mirror mount  22 , described hereinafter with specific reference to  FIG. 6 , to the windshield  52  proximate to the top  64  of the windshield  52 . The rear view mirror  20  is centrally located between the driver side fold down visor  16  and the passenger side fold down visor  18 . The sides of the rear view mirror  20  are not flush against the sides of the driver side fold down visor  16  and the passenger side fold down visor  18 . 
   The sun glare shield  10  is attached to the windshield  52  by the attachment device  26 . The sun glare shield  10  is positioned on the windshield  52  so that the top side  32  of the shield  10  is flush against the top  64  of the windshield  52  and the front side  36  faces the interior of the vehicle  12 . The sun glare shield  10  is also positioned on the windshield  52  so that the space on the windshield  52  between the driver side fold down visor  16  and the rear view mirror  20 , when the driver side fold down visor  16  is in the folded down position, is covered by the sun glare shield  10 ; the space on the windshield  52  between the passenger side fold down visor  18  and the rear view mirror  20 , when the passenger side fold down visor  18  is in the folded down position, is covered by the sun glare shield  10 ; the space on the windshield  52  between the rear view mirror  20  and the top  64  of the windshield is covered by the sun glare shield  10 ; and the space on the windshield  52  below the rear view mirror  20  and between the driver side  16  and passenger side  18  fold down visor is covered by the sun glare shield  10 . 
   Herein, the user  24  is driving the vehicle  12 . Both the driver side  16  and the passenger side  18  fold down visors are in the folded up position. Although the driver side  16  and the passenger side  18  fold down visors are in the folded up position, the sun glare shield  10  remains attached to the windshield  52  so that the windshield  52  between the driver side  16  and the passenger side  18  fold down visors, when both  16  and  18  are folded down, is not visible to the user  24 , while at the same time allowing the driver to continue using the rear view mirror  20 . The blocked windshield  52  prevents unwanted sun glare from entering the vehicle and impeding the user&#39;s  24  line of vision thereby causing dangerous driving conditions. Herein, there is no unwanted sun glare. However, the sun glare shield  10  does not need to be removed as it does not impede the user&#39;s  24  view of the road ahead. 
     FIG. 4  is a perspective view of the front of the sun glare shield  10  of the present invention. The sun glare shield  10  includes the left  28 , right  30 , top  32 , bottom  34 , front  36  and back side  38 . The sun glare shield  10  is made from an opaque material, including but not limited to a vinyl, that prevents sun glare  14  from passing therethrough. As discussed hereinabove with specific reference to  FIG. 2 , in an alternate embodiment, the sun glare shield  10  can be made from a material like a mesh, it can be polarized or it can be optically coated. This would enable the user  24  to see through the sun glare shield  10  while at the same time keeping the sun glare  14  from entering the vehicle  12 . Material that is both polarized and optically coated would cause less distortion than a mesh material. Additionally, there are different grades of optical coatings that affect the quality of the glare reduction. 
     FIG. 5  is a perspective view of the sun glare shield  10  of the present invention. The sun glare shield  10  includes the left  28 , right  30 , top  32 , bottom  34 , front  36  and back side  38 . The sun glare shield  10  is made from an opaque material, including but not limited to a vinyl, that prevents sun glare  14  from passing therethrough. A vertical line  40  is centrally located on the front  36  of the sun glare shield  10 . The vertical line  40  extends from the bottom  34  of the sun glare shield  10  to a location proximate to the top  32  of the sun glare shield  10 . The vertical line  40  can be one of printed onto the surface of the front  36  of the sun glare shield  10  or can be partially embedded within the surface of the front  36  of the sun glare shield  10 . In an alternate embodiment, the vertical line  40  can be located solely on or within the surface of the back  38  of the sun glare shield  10 . In another alternate embodiment, the vertical line  40  can be located on or within both the surface of the front  36  and the back  38  of the sun glare shield  10 . 
   The vertical line  40  enables the user  24  to center the sun glare shield  10  about the rear view mirror mount  22 , shown in  FIG. 6 . The user  24  is then able to custom fit the sun glare shield  10  about the rear view mirror mount  22  as will be discussed hereinafter with specific reference to  FIG. 8 . 
     FIG. 6  is an illustrative view of the sun glare shield  10  in use. The sun glare shield  10  includes the left  28 , right  30 , top  32 , bottom  34 , front  36  and back side  38 . The sun glare shield  10  is made from an opaque material, including but not limited to a vinyl, that prevents sun glare  14  from passing therethrough. The vertical line  40  is centrally located on the front  36  of the sun glare shield  10 . The vertical line  40  extends from the bottom  34  of the sun glare shield  10  to a location proximate to the top  32  of the sun glare shield  10 .

The sun glare shield  10  includes the left  28 , right  30 , top  32 , bottom  34 , front  36  and back side  38 . The sun glare shield  10  is made from an opaque material, including but not limited to a vinyl, that prevents sun glare  14  from passing therethrough. The vertical line  40  is centrally located on the front  36  of the sun glare shield  10 . The vertical line  40  extends from the bottom  34  of the sun glare shield  10  to a location proximate to the top  32  of the sun glare shield  10 . 
   The vertical line  40  enabled the user  24  to center the sun glare shield  10  about the rear view mirror mount  22 . Shown herein, the user  24  created the mirror aperture  50  from the user defined cut template  46 , shown in  FIG. 8 . The mirror aperture  50  was created so that it was vertically centered about the vertical line  40 . The creation of the mirror aperture  50  is not limited to the method described hereinabove with specific reference to  FIG. 8 , and any method to create the mirror aperture  50  could be used. The mirror aperture  50  permits the sun glare shield  10  to be custom fit around the rear view mirror mount  22  and still prevent sun glare  14  from entering the vehicle  12 . After customization, the sun glare shield  10  is attached to the windshield  52  by the attachment device  26 . 
     FIG. 10  is a sectional view of the sun glare shield  10  of the present invention. Herein, the sun glare shield  10  has being customized to fit around the rear view mirror mount  22 . The sun glare shield  10  includes the left  28 , right  30 , top  32 , bottom  34 , front  36  and back side  38 . The sun glare shield  10  is made from an opaque material, including but not limited to a vinyl, that prevents sun glare  14  from passing therethrough. The vertical line  40 , shown in  FIG. 9 , is centrally located on the front  36  of the sun glare shield  10 . The vertical line  40  extends from the bottom  34  of the sun glare shield  10  to a location proximate to the top  32  of the sun glare shield  10 . The vertical line  40  enabled the user  24  to center the sun glare shield  10  about the rear view mirror mount  22  and create the user defined cut template  46 . From the user defined cut template  46 , the user  24  was able to make the mirror aperture  50  so that the sun glare shield  10  could be customized to fit around the rear view mirror mount  22  and still prevent sun glare  14  from entering the vehicle  12 . After customization, the sun glare shield  10  is attached to the windshield  52  by the attachment device  26 .

The sun glare shield  10  is made from an opaque material, including but not limited to a vinyl, that prevents sun glare  14  from passing therethrough. The vertical line  40  is centrally located on the front  36  of the sun glare shield  10 . The vertical line  40  extends from the bottom  34  of the sun glare shield  10  to a location proximate to the top  32  of the sun glare shield  10 . 
   Herein the rear view mirror  20  is attached to the overhead mirror mount  42 . Because the overhead mirror mount  42  extends from the roof of the vehicle  12  instead of the windshield  52 , the sun glare shield  10  does not have to be customized to fit around overhead mirror mount  42 . Rather, the sun glare shield  10  can be directly attached to the windshield  52  by the attachment device  26  without alteration. However, the vertical line  40  can still be used as a guide to center the sun glare shield  10  behind the mirror  20 . 
     FIG. 12  is a perspective view of an alternate embodiment of the sun glare shield  10  of the present invention. The sun glare shield  10  includes the left  28 , right  30 , top  32 , bottom  34 , front  36  and back side  38 .
