    摘要： Concentric ring, single vision lens designs are disclosed which improve the depth-of-focus of the lens relative to current spherical contact lenses or intraocular lenses by placing at least one additional peripheral optical radius on the front or back surface of the lens. A plurality of concentric annular rings are provided in the periphery of the optic zone of the lens. The arrangement of optic powers in the concentric annular rings includes a mixture of the basic spherical refractive power and other annular rings with less plus or greater minus spherical refractive power, arranged to mediate spherical aberrations and improve visual acuity. The concentric annular ring design corrects peripheral, aperture-dependent ocular aberrations in a discrete, zonal fashion.

    摘要： Non-ballasted, eyelid rotationally stabilized designs are disclosed for use in toric or multifocal toric contact lenses. The back surface of the lens includes a toric or multifocal toric surface and also thin top and bottom zones (slab offs) to achieve eyelid rotational orientation and stabilization. The advantage of this technical approach is in mold manufacturing, wherein the design allows the use of any chosen power spherical stock front mold.

    摘要： A multifocus, concentric annular ring lens wherein one of the front and back surfaces of the lens defines a central area comprising a circular disc having a spherical surface corresponding to a basic prescription Rx spherical distance optical power. A plurality of annular rings surround the central area and have alternating spherical near and distance optical powers, and at least one intermediate optical power annular ring. The immediate optical power annular ring is located in the middle or outer region of the lens optic zone, and its optical power is intermediate to the distance and near optical powers, to provide visual acuity at intermediate distances. The intermediate optical power annular ring can be placed anywhere in the middle or outer region of the lens optic zone, and can be the second annular ring from the outer edge of the lens optic zone, or can be the outermost annular ring which defines the outer circumference of the lens optic zone. The lens can be a contact lens to be worn on the cornea of the eye, such as a soft hydrogel contact lens, or can be an intraocular lens.
