s ears to hold glasses 10 in place , are well known in the art , a detailed disclosure of these elements is not provided here . the shape of the lenses and frames can be generally as desired , as long as the desired upper and lower fields of vision are provided as described herein . typically , the shape of the lenses will generally correspond to the associated lens support to facilitate mounting of the lens . also , generally , lens supports 20 and 22 will be open along the bottom portion of lenses 14 ′ and 14 ″ ( i . e ., frame 12 does not extend along the bottom edges of lenses 14 ′ and 14 ″.) to avoid any viewing obstruction below the bottom edges of the lenses . alternatively , a relatively thin frame support ( not shown ) could be provided below bottom edges 40 ′ and 40 ″. in addition , typically bottom edges 38 ′ and 38 ″ of lenses 14 ′ and 14 ″. will be straight or generally straight to provide the desired upper and lower vertical viewing fields . some curvature could be provided in the bottom edge , such as a concave or a convex curvature , particularly a concave curvature . when eyeglasses 10 are worn with frame 12 positioned in place on the upper bridge of the wearer &# 39 ; s nose n as shown in fig5 left lens 14 ′ is in optical registry with the wearer &# 39 ; s left eye , and right lens 14 ″ is in optical registry with the wearer &# 39 ; s right eye to create an upper corrected vertical field of vision through lenses 14 ′, 14 ″ for viewing objects at a distance . the closest distance of lenses 14 ′, 14 ″ to the outer center of the wearer &# 39 ; s cornea is the standard typical distance for eyeglasses , usually in the range of about 5 to 30 mm , for example , when measured in a horizontal plane . glasses 10 create an upper vertical field of vision b for viewing distant objects through the lenses . lenses 14 ′, 14 ″ have top edges 24 ′, 24 ″, bottom edges 38 ′, 38 ″, sides 26 a ′, 26 a ″ on left lens 14 ′ and sides 26 b ′, 26 b ″ on right lens 14 ″. bottom edges 38 ′, 38 ″ substantially align horizontally near the lower half of the wearer &# 39 ; eye , typically at a selected point in the range of about from 3 mm beneath the center of the wearer &# 39 ; s pupil to about 3 mm beneath the bottom edge of the wearer &# 39 ; s cornea . such positioning creates a lower vertical uncorrected field of vision a below the bottom edge of the lenses for viewing objects such as object j close - up without repositioning the frame . the field of the viewing areas for both distance ( upper field ) and near vision ( lower field ) depends upon where bottom edges 38 ′, 38 ″ align with respect to the wearer &# 39 ; s eye and the distance of the lenses from the eyes . generally , the upper vertical field of vision ( corrected by the lenses ) for distant objects ranges from about 55 degrees to about 90 degrees and in general is smaller when bottom edges 38 ′, 38 ″ are positioned nearer the pupil . the lower uncorrected vertical field of vision for viewing nearby objects and tasks — i . e ., without lens correction — ranges from about 40 degrees to about 80 degrees in general and is smaller when bottom edges 38 ′, 38 ″ are positioned vertically farther down from the pupil . in general , the ratio of distance - viewing to near - viewing vertical field angles should be in the range of about 0 . 68 : 1 to about 2 . 25 and more typically should be in the range of about 1 . 07 to about 1 . 88 . in the preferred embodiment shown in fig1 and 5 , bottom edges 38 ′, 38 ″ substantially align with the bottom edge of the wearer &# 39 ; s cornea . in this embodiment , as shown in fig3 glasses 10 create an upper vertical field of vision b of about 85 degrees for viewing distant objects through the lenses ( corrected vision ). as shown in fig2 glasses 10 also provide a lower uncorrected vertical field of vision a of about 50 degrees ( below bottom edges 38 ′, 38 ″.) for viewing close - up objects without the wearer having to reposition frame 12 . in this embodiment , the ratio of the upper field to the lower field angles is about 1 . 7 . fig4 and 7 - 8 illustrate another embodiment of the present invention . as shown , eyeglasses 10 ′, similar to glasses 10 , are positioned on the upper bridge of the nose n of wearer w . eyeglasses 10 ′ comprise components similar to eyeglasses 10 and include a frame 12 ′ which includes a left lens support 20 ′ and a right lens support 22 ′. a left lens 28 ′ and a right lens 28 ″ are fixed in left lens support 20 ′ and right lens support 22 ′, respectively , and extend downwardly from lens supports 20 ′, 22 ′. bridge 16 ′ connects lens supports 20 ′, 22 ″. the height of lenses 28 ′ and 28 ″ and of lens supports 20 ′ and 22 ′ is slightly less than the height of corresponding components of eyeglasses 10 , so that the upper and lower viewing angles are changed as shown in fig7 and 8 and as hereinafter described . temple bars 32 ′ are pivotably attached to frame 12 ′ for supporting eyeglasses 10 ′ in position . when frame 12 ′ is worn normally , lenses 28 ′, 28 ″ are in optical registry with the wearer &# 39 ; s left eye and right eye , respectively . lenses 28 ′, 28 ″ have top edges 34 ′, 34 ″. bottom edges 40 ′, 40 ″, sides 46 a ′, 46 a ″ on left lens 28 ′ and sides 46 b ′, 46 b ″ on right lens 28 ″. bottom edges 40 ′, 40 ″ are unobstructed by frame 12 ′ and are located a vertical distance x of about 3 mm below the center of the wearer &# 39 ; s pupil . such positioning creates an upper vertical corrected field of vision b ′ for viewing distant objects arid a lower uncorrected vertical field of vision a ′ below the bottom edge of the lenses for viewing objects close - up without repositioning the frame . field a ′ for near objects is about 75 degrees and the upper limit of that field is about 3 degrees below horizontal line d as indicated by angle c in fig7 . area b ″ of vision for distant objects , with lens correction , is about 63 degrees . in this embodiment , the ratio of distance - viewing area to near - viewing area is typically about 0 . 84 . fig6 and 9 - 10 illustrate yet another embodiment of the present invention . eyeglasses 10 ″ comprise components similar to eyeglasses 10 and include a frame 12 ″ which includes a left lens support 20 ″ and a right lens support 22 ″, connected by a bridge 16 ″. fixed in left lens support 20 ″ and right lens support 22 ″ are a left lens 30 ′ and a right lens 30 ″, respectively . lenses 30 ′, 30 ″ extend downwardly from lens supports 20 ″, 22 ″. when frame 12 ″ is positioned on the bridge of the wearer &# 39 ;
