Method and apparatus for determining decentration of ophthalmic lenses
A method and apparatus for a diagnostic lens to determine decentration from the optical axis or pupil center in the manufacture of a prescription ophthalmic lens.
METHOD OF MANUFACTURING AN OPHTHALMIC LENS
Disclosed is a method of manufacturing an ophthalmic lens to be mounted into a frame, including: a step of acquiring an optical prescription for the future wearer of the ophthalmic lens and an information relative to the ophthalmic lens and/or to the future wearer and/or to the frame; a step of calculating a surfacing instruction of the ophthalmic lens, the surfacing instruction being determined so that the ophthalmic lens once surfaced satisfies the optical prescription; and a step of surfacing during which the at least one optical face of the ophthalmic lens is surfaced according to the surfacing instruction. During the step of calculating, the surfacing instruction is calculated so that the optical face of the ophthalmic lens once surfaced includes a mark that results from the step of surfacing and that forms a code associated with the information.
METHODS AND SYSTEMS FOR DIAGNOSIS AND TREATMENT OF A DEFINED CONDITION, AND METHODS FOR OPERATING SUCH SYSTEMS
Disclosed herein, inter alia, are a method, system and a kit for improving a defined condition in a subject, the method comprising selecting a set of one or more correction zones, being surface zones on the surface of the subject's skin or defined angular zones in the subject's field of view, the one or more correction zones being associated with the condition; and placing the one or more correcting elements in said one or more correction zones to thereby cause improvement in said condition. Also provided herein are methods and systems for providing such correction zones related to a defined condition in a subject or to a defined cause in a subject being associated with a defined condition.
Method for processing an unfinished optical lens member
A method implemented by computer for processing an unfinished optical lens member for manufacturing an optical lens, the unfinished optical lens member having an unfinished surface and an aspherical finished surface having a first reference system with a first reference point, and the optical lens to be manufactured including first and second surfaces, the first surface including a second reference system with a second reference point and included in the aspherical finished surface of the lens member, the method including: providing an unfinished optical lens member data; providing an optical function; providing a reference point position; providing an optical lens parameter; determining a reference system; determining a first surface dataset; and determining a second surface dataset.
Lenses with optical markings
A lens including a posterior surface, an anterior surface, and at least one identification marking on the lens. The at least one identification marking exhibits a first degree of visibility in an ambient lighting condition and a second degree of visibility greater than the first degree of visibility in a lighting condition different than the ambient lighting condition.
Device to prevent retinal hypoxia
A contact lens configured to decrease dark adaptation comprises one or more LEDs and directs light from the LED away from the fovea and toward the parafovea or perifoveal regions of the retain. In some embodiments, soft contact lens embedded with one or more arrays of microLEDs and electronics operating the LEDs is configured to be worn at night in order to inhibit dark adaptation and reduce oxygen consumption by the rods. The contact lens may be made of a single layer of a contact lens material or multiple layers sandwiching a flexible transparent plastic layer comprising the electronics and the LED arrays. The contact lens may be made of a hydrophilic hydrogel material that is biocompatible to the human cornea, or a silicone hydrogel material. The contact lens may be spherical and may provide refractive correction to the eye of the wearer.
METHOD OF CALCULATING A FINISHED LENS
A finished lens with a predetermined shape, including one front face, one back face and a perimeter corresponding to the shape, including a prescription part on the lens that together with the front face fulfills prescription data of a wearer and a peripheral part on the lens, the prescription part being delimited by a thickness curve and the peripheral part extending from the thickness curve towards an outer edge of the lens, the thickness curve corresponding to a value of thickness less than or equal to a predetermined thickness requirement.
OPHTHALMIC LENSES FOR TREATING MYOPIA
Eyeglasses are disclosed that include eyeglass frames and a pair of ophthalmic lenses mounted in the frames. The lenses include a dot pattern distributed across each lens, the dot pattern including an array of dots spaced apart by a distance of 1 mm or less, each dot having a maximum dimension of 0.3 mm or less, the dot pattern including a clear aperture free of dots having a maximum dimension of more than 1 mm, the clear aperture being aligned with a viewing axis of a wearer of the pair of eyeglasses.
OPHTHALMIC LENSES AND METHODS FOR CORRECTING, SLOWING, REDUCING, AND/OR CONTROLLING THE PROGRESSION OF MYOPIA IN CONJUNCTION WITH USE OF ATROPINE OR RELATED COMPOUNDS
An ophthalmic lens for treating myopia comprising: a base lens with a front surface, a back surface, and a first power profile selected to correct or substantially correct for a distance refractive error of the eye; one or more myopia control elements on at least one of the front and back surfaces of the lens; a first viewing region having a dimension selected based, at least in part, on a concentration of a pharmaceutical agent for use in conjunction with an ophthalmic lens, the first viewing region being configured to minimize, reduce and/or eliminate vision disturbances for distance vision; and a second viewing region comprising a power profile that is relatively more positive compared to the first viewing region; wherein at least one of the size of the second viewing region and the relatively more positive power of the second viewing region is selected based, at least in part, on the concentration of the pharmaceutical agent.
LENS HOLDER AND METHOD OF USE
A lens holder assembly (49) and method of using the lens holder assembly (49) to mark an ophthalmic lens (3) is provided. The lens holder assembly (49) comprises a stem (61) having a central axis and a first opening (5) extending along the central axis of the body (65), a second opening (7) integrated within the stem (61) such that the second opening (7) is substantially parallel to the first opening (5), and at least one illumination source positioned within the second opening (7). The illumination source is capable of emitting light through the second opening (7) for illuminating at least a portion of an ophthalmic lens (3). At least a portion of the lens (3) is placed over the first opening (5). Suction is applied to the lens (3), and a marking is applied to a surface of the lens (3).
