Multifocal Patents (Class 351/159.41)
  • Patent number: 10442774
    Abstract: Methods and systems are disclosed relating to a lens system that allows for simultaneous focus of near and far-away images with one pair of glasses, heads-up-displays (HUDs), and the like, without the need to move the user's eyes. This lens system may be used in a HUD application, for example, where the user may focus on a display lens that may be approximately one inch from the eye to view computer-generated information such as altitude, temperature, directions, and the like, and simultaneously view the individual's surroundings. The lens system may include a liquid lens that when modulated may vary from a near-focus state to a far-focus state rapidly by using an electrowetting or piezoelectric hydraulic actuator. This variable rate lens may be multiplexed at a rate that allows both near and far-away images to appear in focus simultaneously through the advantageous use of a user's persistence of vision.

  • Patent number: 10379380
    Abstract: Translating contact lenses which are truncated for correcting presbyopia and whose design is optimized to maximize translation ability while maintaining comfort when the lens is worn on eye. Truncation of the lenses results in a non-round geometry while still retaining under-lid residency in select portions of the lens itself. Maximum thickness and back surface radius of curvature along with ramp shape can be optimized individually or in combination to maximize translation of the lens relative to the eye, when the lens is positioned on eye.

  • Patent number: 10240741
    Abstract: A fog lamp for use in an automobile includes a light source, a reflector, and a condenser lens. The front surface of the condenser lens includes an emission region and two diffusion regions. The diffusion regions have a surface treatment that diffuses transmitted light, such as knurling, frosting, texturing, or pillowing. Light emitted by the light source is directed by the reflector through the condenser lens and exits the condenser lens through the emission region. Light that enters the condenser lens through one of the diffusion regions from outside of the lamp, such as solar light, is diffused and reduced in intensity. The diffusion regions may be positioned relative to a back surface of the lens to cause the diffused light to be reflected due to total internal reflection. The diffused light may exit the lens through the other diffusion region and become further diffused and reduced in intensity.

  • Patent number: 10028825
    Abstract: 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.

  • Patent number: 9477097
    Abstract: A contact lens for use in controlling or retarding the progression of myopia in an eye has a central optical zone approximating the normal diameter of the pupil of the eye that gives clear central vision at distance for the wearer. An annular peripheral optical zone that is substantially outside the diameter of the pupil is formed around the central optical zone with greater refractive power than that of the central zone so that oblique rays entering the eye through the peripheral optical zone will be brought to focus at a focal plane that is substantially on or anterior to the peripheral region of the retina. Preferably, the rear surface of the lens is shaped to conform to the cornea of the eye and the front surface of the lens is shaped to provide—in conjunction with the rear surface—the desired optical properties of the central and peripheral optical zones.

  • Patent number: 9164294
    Abstract: A method for manufacture of spectacle glasses from prefabricated blanks made without cutting. Each prefabricated blank has a front side not to be finished and an opposite back side. The front side and the back side have at least one optical focus in common. The method includes finishing the back side by calculating a prescription surface based on a prescription of a person. The prescription describes the vision defects of a left and a right eye of the person. The machined back side and the front side together form a first prescription lens and a second prescription lens. The method further includes making first and second spectacle glasses from the first and second prescription lenses. Focal points of the first spectacle glass correct the vision defect of the left eye and focal points of the second spectacle glass correct the vision defect of the right eye of the person.

  • Publication number: 20140347623
    Abstract: A viewer includes a multifocal lens capable of setting one of a plurality of focal lengths. When a measuring section detects a change in gazing point distance, a selection section selects a focal length to be set among the plurality of focal lengths, and a determiner determines a time duration before a focal length of the multifocal lens is changed. A controller changes the focal length of the multifocal lens when a detector detects a blink or saccadic eye movement of the user before the determined time duration elapses.

  • Patent number: 8833936
    Abstract: A progressive ophthalmic lens element is disclosed. The progressive ophthalmic lens element includes an upper viewing zone, a lower viewing zone, a corridor, and a peripheral region disposed on each side of the lower viewing zone. The upper viewing zone includes a distance reference point (DRP) and a fitting cross, and provides a first refractive power for distance vision. The lower viewing zone, which is for near vision, provides an addition power relative to the first refractive power. The corridor connects the upper and lower zones and provides a refractive power varying from that of the upper viewing zone to that of the lower viewing zone. Each peripheral region includes a zone of positive power relative to the addition power which provides therein a positive refractive power relative to the refractive power of the lower viewing zone.
