Peripheral filtering optical eyeglasses
A filter or lens for common optical apparatus includes a clear center portion and an attenuating peripheral portion where the peripheral portion attenuates off-axis images and passes on-axis images with high signal to noise ratios yet not completely blocking the off-axis images, which lens is well suited for reducing off-axis glare in the optical apparatus that may be handheld optical apparatus such as binoculars, telescopes, cameras, and eyeglasses.
1. Optical eyeglasses, the apparatus comprising,
a filter having an inner portion and an outer portion,
the outer portion extending to the periphery of the filter and for attenuating an off-axis image,
the off-axis image being a peripheral image passing through the outer portion,
the filter further comprising an inner portion for passing the on-axis image, the inner portion attenuating the on-axis image lesser than the attenuation of the off-axis image passing through the outer portion, and
a frame for supporting the filter, the frame adapted for resting on a nose and a pair of ears of a human being,
wherein, the filter comprises two lenses and the frame is adapted for use in eyeglasses for providing vision for a human being, the lenses having a focal point in eyeballs of the human being.
2. Optical eyeglasses, the apparatus comprising,
a filter having an inner portion and an outer portion,
the outer portion extending to the periphery of the filter and for attenuating an off-axis image,
the off-axis image being a peripheral image passing through the outer portion,
the filter further comprising an inner portion for passing the on-axis image, the inner portion attenuating the on-axis image lesser than the attenuation of the off-axis image passing through the outer portion, and
a frame for supporting the filter, the frame adapted for resting on a nose and a pair of ears of a human being,
wherein, the filter comprises two lenses, the lenses being corrective lenses, and the frame is adapted for use in a pair of eyeglasses for providing vision for a human being, the lenses having a focal point in eyeballs of the human being.
3. A method of improving eyeglasses, the method comprising the steps of,
providing a filter having an inner portion and an outer portion,
locating more than two attenuating geometric shapes on the filter to attenuate an off-axis image passing through the filter outer portion,
passing an on-axis image through the filter inner portion,
as compared to the on-axis image, attenuating the off-axis image to a greater degree, and
supporting the filter with a frame adapted for resting on a nose and a pair of ears of a human being.
4. The method of claim 3 wherein the attenuating geometric shapes are reflective.
5. The method of claim 3 wherein the attenuating geometric shapes are reflective on the image side but, through the lens, are attenuating and viewable by a human being.
6. Optical eyeglasses, the apparatus comprising,
a filter having an inner portion and an outer portion,
the outer portion extending to the periphery of the filter and for attenuating an off-axis image,
the off-axis image being a peripheral image passing through the outer portion,
the filter further comprising an inner portion for passing the on-axis image, the inner portion attenuating the on-axis image lesser than the attenuation of the off-axis image passing through the outer portion,
a frame for supporting the filter, the frame adapted for resting on a nose and a pair of ears of a human being and the filter comprising two lenses,
the outer portion comprises two edge portions for reducing glare from the off-axis image while not attenuating top and bottorn off-axis images, and
the frame is adapted for use in a pair of eyeglasses for providing vision for a human being, the lenses having a focal point in eyeballs of the human being.
7. A method of improving eyeglasses, the method comprising the steps of,
providing an uncolored filter including an outer portion and an inner portion,
passing an on-axis image with the inner portion,
attenuating an off-axis image with the outer portion,
as compared to the on-axis image, attenuating the off-axis image to a greater degree,
supporting the filter with a frame adapted for resting on a nose and a pair of ears of a human being, and
including attenuating shapes in the outer portion.
8. The method of claim 7 wherein the attenuating shapes include a plurality of reflective attenuating shapes, each reflective attenuating shape framed within an otherwise transparent region of the outer portion.
9. A method of improving eyeglasses, the method comprising the steps of,
providing an uncolored filter including an outer portion and an inner portion,
passing an on-axis image with the inner portion,
attenuating an off-axis image with the outer portion,
as compared to the on-axis image, attenuating the off-axis image to a greater degree,
supporting the filter with a frame adapted for resting on a nose and a pair of ears of a human being, and
providing in the outer portion a plurality of equiangularly spaced opaque triangular portions and a plurality of equiangularly spaced transparent triangular portions.
10. A method of improving eyeglasses, the method comprising the steps of,
providing an uncolored filter including an outer portion and an inner portion,
passing an on-axis image with the inner portion,
attenuating an off-axis image with the outer portion,
as compared to the on-axis image, attenuating the off-axis image to a greater degree,
supporting the filter with a frame adapted for resting on a nose and a pair of ears of a human being, and
providing in the outer portion an attenuation profile that varies along any radial line from a center in the inner portion of the filter through the filter's outer portion.
11. A method of improving eyeglasses, the method comprising the steps of,
providing an uncolored filter including an outer portion and an inner portion,
passing an on-axis image with the inner portion,
attenuating an off-axis image with the outer portion,
as compared to the on-axis image, attenuating the off-axis image to a greater degree,
supporting the filter with a frame adapted for resting on a nose and a pair of ears of a human being,
providing in the outer portion an attenuation profile that varies along any radial line from a center in the inner portion of the filter through the filter's outer portion, and
wherein the variation of the attenuation profile is stepwise.
12. The method of claim 11 wherein the variation of the attenuation profile is continuous.
