The present disclosure is directed to lenses, devices, methods and/or systems for addressing refractive error. Certain embodiments are directed to changing or controlling the wavefront of the light entering a human eye. The lenses, devices, methods and/or systems can be used for correcting, addressing, mitigating or treating refractive errors and provide excellent vision at distances encompassing far to near without significant ghosting. The refractive error may for example arise from myopia, hyperopia, or presbyopia with or without astigmatism. Certain disclosed embodiments of lenses, devices and/or methods include embodiments that address foveal and/or peripheral vision. Exemplary of lenses in the fields of certain embodiments include contact lenses, corneal onlays, corneal inlays, and lenses for intraocular devices both anterior and posterior chamber, accommodating intraocular lenses, electro-active spectacle lenses and/or refractive surgery.

An optical element comprising an object-side imaging element for imaging an object on an intermediate image plane in an optical path before a final image plane and an image-side imaging element for reimaging an object image formed on the intermediate image plane, on the final image plane, wherein at least one of the object-side imaging element and the image-side imaging element comprises an off-axial curved surface, and wherein aberration is generated by both of the object-side imaging element and the image-side imaging element, thereby flattening (disturbance of) a light intensity distribution caused on the final image plane by a noise source at or near the intermediate image plane

Optical element and optical apparatus

Certain embodiments are directed to lenses, devices and/or methods For example, a lens for an eye having an optical axis and an aberration profile along its optical axis, the aberration profile having a focal distance and including higher order aberrations having at least one of a primary spherical aberration component C(4,0) and a secondary spherical aberration component C(6,0) The aberration profile may provide, for a model eye with no aberrations and an on-axis length equal to the focal distance: (i) a peak, first retinal image quality (RIQ) within a through focus range that remains at or above a second RIQ over the through focus range that includes said focal distance, where the first RIQ is at least 035, the second RIQ is at least 01 and the through focus range is at least 18 Diopters; (ii) a RIQ of 03 with a through focus slope that improves in a direction of eye growth; and (iii) a RIQ of 03 with a through focus slope that degrades in a direction of eye growth The RIQ may be Visual Strehl Ratio or similar measured along the optical axis for at least one pupil diameter in the range 3 mm to 6 mm, over a spatial frequency range of 0 to 30 cycles/degree inclusive and at a wavelength selected from within the range 540 nm to 590 nm inclusive

PROBLEM TO BE SOLVED: To expand an exit pupil while restraining degradation in the image quality of a display image in a retina scan type display that displays an image by directly projecting a luminous flux onto a retina of an observer and scanning the projected luminous flux on the retina. SOLUTION: A diffraction element is disposed on an optical path between a light source, not shown, and a lens 144, serving as the exit part of the retina scan type display, so as to be out of an intermediate image plane IP1 between the light source and lens 144. The diffraction element is set, for example, between a lens 112 and the lens 114, which compose a first relay optical system disposed between a horizontal scan system and a vertical scan system.

Lenses, Devices, Systems and Methods for Refractive Error

PURPOSE:To obtain a projection optical system in which a Fresnel fringes of Fresnel-elements having a prism operation and a positive power are not projected by arranging optical elements having a periodic construction by shifting toward an optical axis from an intermediate-image position. CONSTITUTION:A pupil conjugation connecting elements (device) 30 is constituted of eccentric Fresnel lenses 31, 32 divided into two sheets, correction lenses 33, 34 inserted between the Fresnel lenses 31 and 32. The center F1 of the eccentric Fresnel lenses 31 and 32 is made eccentric to the center F2 of correction lenses 33 and 34. When the eccentric Fresnel lenses 31 and 34 are arranged by shifting from an inter-mediate image 13 in this way, Fresnel fringes of eccentric Fresnel lenses 31 and 32 are made to be a defocus state to a projection lens 21 of a second projection lens system 20. Thus, the image of the fringes is never formed inside a projected image.

Pupil conjugation connecting device in projection optical system

An intraocular lens member, which is to be placed inside the lenticular capsule and is capable of deforming freely in accordance with deformation of the lenticular capsule. The intraocular lens member has a hollow section. In the central section when the intraocular lens member is viewed in planar view and the outermost surface of the intraocular lens member is called the outer surface and the surface in the intraocular lens member forming the hollow section is called the inner surface, the radius of curvature of the outer surface and the radius of curvature of the inner surface differ from each other in the anterior capsule portion and/or the posterior capsule portion.
