| PURPOSE: To provide a double focus type ophthalmologic lens having no inherent physiological defect, i.e., capable of allowing tears to suitably flow on the center of a cornea while utilizing a closed ring type concentrical circle depending upon optical phase operation to obtain a refractive power. CONSTITUTION: Relating to the multi-focus type ophthalomologic lens, a spiral pattern is formed on a section applied to a lens user's cornea out of the surface of the lens and plural different refractive power components are presented by the spiral pattern. | ||||||

| PURPOSE: To correct or alleviate presbyopia by making two lenses so that one lens has the capability of forming high intensity image corresponding to a low intensity image formed on the other, and then wearing the lenses on both eyes respectively. CONSTITUTION: A user has the first contact lens 1 attached to the left eye and the second contact lens 2 attached to the right eye. The first contact lens 1 is designed and prepared on the basis of a refracted image as a near-sight image, and a diffracted image as a far-sight image. Also, the second contact lens 2 is designed and prepared on the basis of a refracted image as a far-sight image and a diffracted image as a near-sight image. Furthermore, the contact lenses 1 and 2 are both designed to have a diffracted image weaker than a refracted image. The weakened diffracted image, however, exists and act to gives stereo acuity of such an extent as remarkably increased. In this case, the selection of the contact lenses 1 and 2 for use in the right or the left eye depends on several factors, but almost all people prefer looking at a far away object via the eye of acuity.

| PURPOSE: To effectively exhibit double focus characteristics even when the aperture diameter is small by providing a braze plane, in which each odd- numbered zone has the optical path length of half of the optical path length of each even-numbered face, and composing an optical device of a phase zone plate provided with the annular concentric zone of a contour having discontinuous jump on the radius of each odd-numbered zone. CONSTITUTION: A diffraction type double focus optical element is provided with a braze plane B, in which the gap of zones is almost proportional to k and odd-numbered zones r 1-r 15 have the optical path length (depth) of half of the optical path length (depth) of even-numbered zones r 2-r 16, and composed of a phase zone plate A equipped with the annular concentric zone of the contour having the discontinuous jump on the radius of each odd-numbered zone. Namely, all the cyclic zones reduced as much as possible are provided with two different half cyclic zones so as to be zones sized minimum irreducibly for providing an effective image at focal points more than one along the central axial line of the phase zone plate A. Thus, even when the aperture diameter reduced almost at the degree of one full periodic zone is used, the double focus effect can be provided. COPYRIGHT: (C)1991,JPO | ||||||

| PURPOSE: To realize totally new astigmatism correction by providing a diffraction structure having the outline of a conical section curve having a non- regression center for an optical lens. CONSTITUTION: The lens has adjacent diffraction structure having the boundary of the conical curve having not a circle but the non-regression center around an optical shaft. It is desirable that the outline of an adjacent diffraction area is an ellipse or a hyperbola. In such a case, the boundary means the boundary of the adjacent diffraction areas. Mutual brightness/darkness areas show the periodicity of diffraction structure and the diffraction area is generated by a brightness area and the adjacent darkness area. Thus, astigmatism can be corrected in the same way as a regular cylindrical face lens. COPYRIGHT: (C)1991,JPO | ||||||

| PURPOSE: To make it possible to obtain a contact lens having astigmatism correcting power by diffraction by forming a series of substantially linear parallel zones by diffracting means and decreasing inter-zone spacings to at least either of the linear axes. CONSTITUTION: This lens has a lens body 2 and the two diffracting means. One thereof diffracts light mainly in one direction to the one degree and is formed as the series of the substantially linear parallel zones. The inter-zone spacings decrease to either of the axes IV-IV' of the linear shape. The other is a hologram formed by a concentric ellipse having a high aspect ratio. The means having the linear zones and the nearly circular zones are superposed on each other, by which the lens body having the power of the spherical lens and the power of the columnar lens in common is obtd. and the bifocal artificial lens having the function to correct the astigmatism is obtd.

| 276 | Multi-focal point phase plate | JP28659788 | 1988-11-10 | JPH02137815A | 1990-05-28 | AREN ERU KOOEN |
| PURPOSE: To apply two clear images to an eye once by using the phenomenon of simultaneous visual field. CONSTITUTION: This device is provided with a plurality of annular concentric areas spaced according to an expression I. In the expression I, r(k) expresses an area radius, and (k) expresses an area, and the side of a multi-focal point phase plate is provided with a continuous step, and an optical path length which is larger or smaller than a half-wave length is provided. That is, the annular area is spaced to obtain the integral number of phases with the half-wave length. In this case, a lens can be completely analyzed only by looking at a few areas forming continuous patterns for the lens as a whole. Thus, two clear images can be applied to an eye once.

| PURPOSE: To generate a wave head by the result of the influence of the interference of the wave head radiated from a phase plate by providing at least two phase plates in an optical area. CONSTITUTION: A 'phase late' is the single optical part of a lens using the combination of an area plate with an optical face in the area, and the combination forms a prescribed wave head for diffracting a light, and generating the prescribed strength distribution of the light at the focal point of the various orders (zero order, one order or the like) of the area plate. That is, in a half- wave length two focal point phase plate having an echelette E with depth (h), amplitudes (a) 0 and (a) 1 of a light are formed by each echelette E, and conclusive synthetic amplitudes A 0 and A 1 of the light formed at zero order and one order diffraction focal points f 0 and f 1. Thus, convergence can be moved from a far point to a near point with the adjusting function of the pupil of the eye of a human being which normally contracts when viewing the near point by the two focal point capability of the lens.

| PURPOSE: To desirably distribute light for a near focus and a far focus by providing a phase zone plate of the specification of cohen lens containing repetitive patterns having curves. CONSTITUTION: A diffraction grating provided with the phase zone plate of cohen lens specification containing the repetitive pattern which is designed to operate with a specified wavelength, is bent in an r 2 space, is rotation symmetric and has the curve is used. The brazed grating can adjust the distribution of light between two focuses by adjusting the depth Do of a facet and the profile of the brazed facet itself. Thus, light can desirably be adjusted at the two focuses. COPYRIGHT: (C)1990,JPO | ||||||

| Apparatuses, systems and methods for providing improved intraocular lenses (IOLs), include features for reducing side effects, such as halos, glare and best focus shifts, in multifocal refractive lenses and extended depth of focus lenses. Exemplary ophthalmic lenses can include a continuous, power progressive aspheric surface based on two or more merged optical zones, the aspheric surface being defined by a single aspheric equation. Continuous power progressive intraocular lenses can mitigate optical side effects that typically result from abrupt optical steps. Aspheric power progressive and aspheric extended depth of focus lenses can be combined with diffractive lens profiles to further enhance visual performance while minimizing dysphotopsia effects. The combination can provide an increased depth of focus that is greater than an individual depth of focus of either the refractive profile or the diffractive profile. | ||||||
