(a) a wearable frame operable for supporting left and right lenses;
(b) left and right lenses affixed to said frame, said left and right lenses having a lens plane and an optical center, and wherein an imaginary line connecting said optical centers of said lenses defines an x-axis and an imaginary line passing through said optical center perpendicular to said horizontal line in said lens plane defines a y-axis, said x-axis and said y-axis collectively defining a polar coordinate system, and wherein an imaginary chord drawn on the lens between 225\xb0 and 15\xb0 partitions said lens into a smaller masked portion and a larger transparent portion;
(c) a masking material affixed directly to said masked portion of said lenses, said masking material being coextensive with said masked portion and having an optical transmissivity between zero and about 10%.
2. The spectacles of claim 1 wherein said optical transmissivity of said masking material is about 10%.
3. The spectacles of claim 1 wherein said frame includes adjustment means operable for changing a distance between said optical centers of said lenses.
4. The spectacles of claim 1 wherein said masking material is a red pass filter.
5. Spectacles for reducing glare from headlights of oncoming traffic while providing a wearer of the spectacles with a clear view of a road ahead while driving at night on a British-type road, the spectacles comprising:
(a) a wearable frame operable for supporting left and right lenses;
(b) left and right lenses affixed to said frame, said left and right lenses having a lens plane and an optical center, and wherein if an imaginary line connecting said optical centers of said lenses defines an x-axis and an imaginary line passing through said optical center perpendicular to said horizontal line in said lens plane defines a y-axis, said x-axis and said y-axis collectively defining a polar coordinate system, a chord drawn on the lens between 345\xb0 and 145\xb0 partitions said lens into a smaller masked portion and a larger transparent portion;
(a) a masking material affixed directly to said masked portion of said lenses, said masking material being coextensive with said masked portion and having an optical transmissivity between zero and about 10%.
