摘要： An ocular telescopic lens system for low-vision conditions such as macular degeneration includes an intraocular lens having a converging lens portion and a diverging lens portion, and multiple-element spectacles having anterior and posterior lenses arranged to converge light toward the diverging lens portion. The intraocular lens includes an optic with a generally continuous rearward surface that combines with a first portion of the forward surface as the converging lens portion and with a second portion of the forward surface as the diverging lens portion, while the anterior and posterior lenses of the spectacles may have concave surfaces, combine to serve as an objective lens, and provide at least +8 diopter power. Mounting components are included for mounting the anterior and posterior lenses on a spectacle frame so that light passes first through the anterior lens and then through the posterior lens in traveling to the eye of a user, and these components may be configured to enable adjustment of the distance by which the anterior lens and the posterior lens are separated while maintaining the anterior lens fixed relative to the spectacle frame so as not to vary the vertex distance.

摘要： A visual aid device is shown for use by a wearer. The device includes a spectacle frame with a pair of carrier lenses mounted on the spectacle frame, each of the lenses having an aperture for receiving a bushing which protrudes through the lens. A bushing is fixedly mounted in each aperture at a predetermined inclination and declination. A quick release mount within each bushing allows the bushings to receive a variety of interchangeable optical devices.

摘要： Eye glasses are disclosed for improving the vision of people with macular degeneration, optic nerve damage or similar low vision problems. The glasses comprise two lens assemblies, each having a magnifying lens with two convex surfaces and a reducing lens with two concave surfaces. The reducing lens incorporates prism rings which focus an image or light onto an undamaged portion of the macular. A frame is employed for supporting each assembly at a predetermined distance from an eye of a user and for supporting the lenses assembly in a predetermined orientation with respect to each other with the lenses defining a fixed space therebetween. Also disclosed are the lenses themselves and the method of using them.

摘要： Binocular eyeglasses are provided for magnification of images, for example, when viewing television or when viewing distant images, such as a sporting event or the like. The binocular eyeglasses comprise a lightweight frame assembly including a lens carrying front frame with rearwardly extending bows permitting the eyeglasses to be worn in a normal manner. The front frame includes eyepiece lenses supported in stationary positions in front of the viewer's eyes and a respective pair of relatively wide-angle and relatively low-power objective lenses movable quickly and easily between close-range and long-range focus setting positions.

摘要： There is disclosed herein a vision aid for doctors, dentists, visually-handicapped, engineers, mechanics, technicians, and the like. The device comprises a conventional eyeglass frame having mounted thereto a pair of plastic elevating plates and which are hinged with respect to the eyeglass frame. One monocular, or a pair of monoculars forming a binocular, can be secured to the elevating plates. The elevating plates are connected together and attached to the hinges in a manner to allow the interocular or pupil distance to be readily set or readjusted, and also allow the monoculars to be adjusted up and down vertically with respect to the axis of the wearer's eyes. The hinged arrangement allows the elevating plates to tilt up to thereby move the monocular or monoculars out of the line of vision, so as to restore the wearer's natural vision or vision as corrected by corrective lenses in the eyeglass frames. The monoculars also are mounted in a manner to allow alignment and re-alignment of the axis of the monoculars to toe in or toe out these lenses so that it can be parrallax adjusted for any close working distance to allow for exact collimation. The overall assembly is relatively simple, compact and lightweight. The monoculars can be fixed focus but generally are lenses of variable focus.
