Claim 6

A glare reducing device for viewing comprising a body of transparent glare reducing sheet material and means for positioning said body transversely in the line of sight of an observer and in a selected forwardly spaced and lateraLly positioned relation to the observer, such body having a selected index of refraction, a selected transverse extent and opposite vertically extending beveled side edge faces each forming a selected interior obtuse angle with that surface of said body facing the observer such that (1) an incoming ray of light passing immediately outside one of said side edge faces and parallel thereto will pass outside the laterally corresponding eye of the observer, (2) an incoming ray of light striking the forward surface of said body immediately within its intersection with said one side edge face so as to be refracted to pass through said body parallel to said one side edge face will be refracted on emerging from said body to pass outside the laterally noncorresponding eye of the observer, (3) an incoming ray of light passing immediately outside the other of said side edge faces and parallel thereto will pass outside the laterally corresponding eye of the observer, and (4) an incoming ray of light striking the forward surface of said body immediately within its intersection with said other side edge face so as to be refracted to pass through said body parallel to said other side edge face will be refracted on emerging from said body to pass outside the laterally noncorresponding eye of the observer, whereby neither of said side edge faces will be visible to either eye of the observer.

Claim 7

In an automobile glare shield having a body of glare reducing sheet material fastened to an automobile sun visor, disposed substantially vertically and provided with a transversely extending substantially horizontal lower edge, so that such body extends below the bottom edge of the sun visor as an extension thereof, the improvement of a main body portion below the bottom edge of the sun visor and means for positioning said main body portion transversely in the line of sight of an observer and in a selected forwardly spaced and laterally positioned relation to the observer, such main body portion having a selected index of refraction and a vertically extending beveled side edge face forming a selected interior obtuse angle with that surface of said main body portion facing the observer such that (1) an incoming ray of light passing immediately outside said side edge face and parallel thereto will pass outside the laterally corresponding eye of the observer, and (2) an incoming ray of light striking the forward surface of said main body portion immediately within its intersection with said side edge face so as to be refracted to pass through said main body portion parallel to said side edge face will be refracted on emerging from said main body portion to pass outside the laterally noncorresponding eye of the observer, whereby said side edge face will not be visible to either eye of the observer.

Claim 8

In an automobile glare shield having a body of glare reducing sheet material fastened to an automobile sun visor, disposed substantially vertically and provided with a transversely extending substantially horizontal lower edge, so that such body extends below the bottom edge of the sun visor as an extension thereof, the improvement of a main body portion below the bottom edge of the sun visor and means for positioning said main body portion transversely in the line of sight of an observer and in a selected forwardly spaced and laterally positioned relation to the observer, such main body portion having a selected index of refraction and a vertically extending beveled side edge face forming a selected interior obtuse angle with that surface of said main body portion facing the observer such that (1) an incoming ray of light passing immediately outside said side edge face and parallel thereto will pass outside the laterally corresponding eye of the observer, and (2) an incoming ray of light striking the forward surface of said main body portion immediately within its intersection with said side edge face so as to be refracted to pass through said main body portion parallel to said side edge face will be refracted on emerging from said main body portion to pass outside the laterally noncorresponding eye of the observer, whereby said side edge face will not be visible to either eye of the observer.

Claim 9

A glare shield constructed according to claim 5 wherein said vertically extending beveled side edge face is a left side edge face.

Claim 10

A glare shield constructed according to claim 5 wherein said vertically extending beveled side edge face is a right side edge face.

Claim 11

In an automobile glare shield having a body of glare reducing sheet material fastened to an automobile sun visor, disposed substantially vertically and provided with a transversely extending substantially horizontal lower edge, so that such body extends below the bottom edge of the sun visor as an extension thereof, the improvement of a main body portion below the bottom edge of the sun visor and means for positioning said main body portion transversely in the line of sight of an observer and in a selected forwardly spaced and laterally positioned relation to the observer, such main body portion having a selected index of refraction, a selected transverse extent and opposite vertically extending beveled side edge faces each forming a selected interior obtuse angle with that surface of said main body portion facing the observer such that (1) an incoming ray of light passing immediately outside one of said side edge faces and parallel thereto will pass outside the laterally corresponding eye of the observer, (2) an incoming ray of light striking the forward surface of said main body portion immediately within its intersection with said one side edge face so as to be refracted to pass through said main body portion parallel to said one side edge face will be refracted on emerging from said main body portion to pass outside the laterally noncorresponding eye of the observer, (3) an incoming ray of light passing immediately outside the other of said side edge faces and parallel thereto will pass outside the laterally corresponding eye of the observer, and (4) an incoming ray of light striking the forward surface of said main body portion immediately within its intersection with said other side edge face so as to be refracted to pass through said main body portion parallel to said other side edge face will be refracted on emerging from said main body portion to pass outside the laterally noncorresponding eye of the observer, whereby neither of said side edge faces will be visible to either eye of the observer.
