Abstract

This invention provides anti-glare eyeglasses for drivers for shielding the glare of on-coming headlights and the glare of headlights of following vehicles reflected in rear view mirrors. The central vision area is bordered by a shaded area on the left side, the edge of the shaded area next to the central vision area is vertical and straight, the shaded area extends to the left at an angle corresponding to the apparent angle at which the on-coming headlights pass to the left of the driver, and additional shaded areas are provided to the left and right for screening the headlight glare of following vehicles reflected in rear view mirrors. The shaded areas may be reversed for use by drivers driving on the left side of the road. The invention also provides a kit of parts of attachable shaded shapes which can be placed on regular eyeglasses to correspond to the eyeglasses of this invention.

Claims

1. Anti-glare eyeglasses for drivers of vehicles, wherein each lens or vision area for each eye comprises:

(a) a central vision area extending substantially to the upper portion and lower portion of the lens area and having sufficient width for the driver to have an unobstructed view, with the driver'"'"'s head in normal position, of straight ahead traffic in the driver'"'"'s side of the roadway from at leat the right side of the roadway to at least the center of the roadway; and

(b) a shaded area being positioned adjacent to the left side of the central vision area and extending outwardly and laterally from said central vision area and having a top boundary, a bottom boundary and a right boundary adjacent to said central vision area, wherein (i) the bottom boundary of the shaded area is substantially straight and is angled to substantially correspond to the apparent angle (A) at which the headlights of on-coming traffic move past the driver whereby the vision area below the apparent angle (A) at which the headlights pass the driver is not screened or obstructed by the shaded area when the eyeglasses are in normal position for screening the on-coming headlights, (ii) the distance between the top and bottom boundaries of the shaded area is sufficient to provide effective screening of the glare of the headlights of the on-coming traffic as the headlights move past the driver, (iii) the right boundary of the shaded area adjacent to the central vision area is substantially straight and vertical and (iv) the shaded area extends outwardly sufficiently to provide effective screening of the on-coming traffic headlight glare substantially to the limit of the driver'"'"'s peripherial vision.

2. Anti-glare eyeglasses according to claim 1 further comprising:

(c) a second shaded area which is positioned outside the left portion of the first shaded area and which extends a sufficient amount to effectively screen the headlight glare of a following vehicle reflected in the exterior rear view mirror to the left of the driver.

3. Anti-glare eyeglasses according to claim 2 further comprising:

(d) a third shaded area which is positioned outside and to the right side of the central vision area and which is positioned to effectively screen the headlight glare of a following vehicle reflected in a rear view mirror positioned to the right of the driver.

4. Anti-glare eyeglasses according to claim 3 wherein the bottom boundaries of the shaded areas are adapted to be initially positioned by the driver so that the shaded areas do not cover the on-coming traffic or mirror fields of the driver'"'"'s vision and are positioned such that the driver can cover those fields of the driver'"'"'s vision with the shaded area by slight movement of the eyeglasses.

5. Anti-glare eyeglasses according to claim 4 wherein the bottom boundaries of the shaded areas are positioned so that each shaded area covers its respective field of vision at different times upon progressive movement of the eyeglasses.

6. Anti-glare eyeglasses according to claim 3 wherein the bottom boundaries of the shaded areas are adapted to be initially positioned by the driver so that the shaded areas cover the on-coming traffic and mirror fields of the driver'"'"'s vision and are positioned such that the driver can uncover those fields of the driver'"'"'s vision from screening by the shaded areas by slight movement of the eyeglasses.

7. Anti-glare eyeglasses according to claim 6 wherein the bottom boundaries of the shaded areas are positioned so that each shahed area covers its respective field of vision at different times upon progressive movement of the eyeglasses.

10. Anti-glare eyeglasses according to claim 2 wherein the bottom boundaries of the shaded areas are adapted to be initially positioned by the driver so that the shaded areas cover the on-coming traffic and mirror fields of the driver'"'"'s vision and are positioned such that the driver can uncover those fields of the driver'"'"'s vision from screening by the shaded areas by slight movement of the eyeglasses.

11. Anti-glare eyeglasses according to claim 10 wherein the bottom boundaries of the shaded areas are positioned so that each shaded area covers its respective field of vision at different time upon progressive movement of the eyeglasses.

17. A kit of parts comprising individual attachable glare-screening components having configurations and being adapted so that said screening components can be attached by mechanical, self-adhering or self-adhesive means to eyeglasses to provide shaded areas as defined in any of claims 1-16.

18. Anti-glare eyeglasses according to claim 1, 2 or 12 wherein the left and right arrangements of the eyeglasses are reversed in mirror image configuration for use in driving on the left side of the roadway.

12. Anti-glare eyeglasses for drivers of vehicles, wherein each lens or vision area for each eye comprises:

(a) a central vision area extending substantially to the upper portion and lower portion of the lens area and having sufficient width for the driver to have an unobstructed view, with the driver'"'"'s head in normal positio, of straight ahead traffic in the driver'"'"'s side of the roadway from at least the right side of the roadway to at least the center of the roadway;

(b) a first shaded area being positioned adjacent to the left side of the central vision area and extending outwardly and laterally from said central vision area and having a top boundary, a bottom boundary and a right boundary adjacent to siad central vision area, wherein (i) the bottom boundary of the shaded area is substantially straight and is angled to substantially correspond to the apparent angle (A) at which the headlights of on-coming traffic move past the driver whereby the vision area below the apparent angle (A) at which the headlights pass the driver is not screened or obstructed by the shaded area when the eyeglasses are in normal position for screening the on-coming headlights, (ii) the distance between the top and bottom boundaries of the shaded area is sufficient to provide effective screening of the glare of the headlights of the on-coming traffic as the headlights move past the driver, (iii) the right boundary of the shaded area adjacent to the central vision area is substantially straight and vertical and (iv) the shaded area extends outwardly sufficiently to provide effective screening of the on-coming traffic headlight glare substantially to the limit of the driver'"'"'s peripheral vision; and

(c) a second shaded area which is positinoed to the right of the central vision area and which is positioned to effectively screen the headlight glare of a following vehicle reflected in the rear view mirror positioned to the right of the driver.

8. Anti-glare eyeglasses according to claim 12 wherein the bottom boundaries of the shaded areas are adapted to be initially positioned by the driver so that the shaded areas do not cover the on-coming traffic or mirror fields of the driver'"'"'s vision and are positioned such that the driver can cover those fields of the driver'"'"'s vision with the shaded areas by slight movement of the eyeglasses.

9. Anti-glare eyeglasses according to claim 8 wherein the bottom boundaries of the shaded areas are positioned so that each shaded area covers its respective field of vision at different times upon progressive movement of the eyeglasses.

13. Anti-glare eyeglasses according to claim 12 wherein the bottom boundaries of the shaded areas are adapted to be initially positioned by the driver so that the shaded areas do not cover the on-coming traffic or mirror fields of the driver'"'"'s vision and are positinoed such that the driver can cover those fields of the driver'"'"'s vision with the shaded areas by slight movement of the eyeglasses.
