Definitions

  • the present invention is in the technical field of eyewear, and more particularly eyewear with multifocal lenses.
  • Multifocal lenses which can be progressives, bi-focals, or tri-focals are characterized by a gradient of increasing lens power. Multifocal lenses allow eyeglass wearers to correct vision in a range of distances, starting with the distance prescription of the wearer at the top of the lenses, and reaching the maximum addition power at the bottom of the lens. An intermediate viewing area is located between the top and bottom of the lens in the case of progressive lenses or tri-focal lenses.
  • a multifocal lens wearer typically is measured and fitted for lenses in person, for example at an office of an opthamologist. Once the measurements are complete, viewing channels are ground into place on the lenses for each individual user and thus the lenses are wearer-specific.
  • multifocal lenses require careful placement relative to the wearer's pupil for a distance-viewing reference position. Poorly fitted lenses can cause problems for the wearer including, for example, narrow fields of view, clear vision in one eye only, and a need to change head position to see clearly.
  • the present invention is a method and platform for obtaining precise measurements to fit multifocal lenses to individual wearers virtually, without an in- person fitting.
  • the method of obtaining precise measurements for manufacturing a multi-focal eyeglass includes providing a frame that includes at least a first opening.
  • the method includes providing a lens dimensioned for receipt in the first opening.
  • the method includes providing multiple indicia on at least one of the frame and the lens that aid in taking measurements of the relative location of the eyes relative to the frame/lens when the frame is mounted on an associated user.
  • the method wherein the indicia providing step includes providing a predetermined pattern on the lens.
  • the method includes creating a first image of the indicia when the frame is mounted on the associated user.
  • the method wherein the image creating step includes taking a photograph of the user wearing the eyeglass frame.
  • the method wherein markings include forming a horizontal axis and a vertical axis.
  • the method includes further providing incremental markings along the horizontal and vertical axes.
  • the method including equally spacing the incremental markings.
  • the method including equally spacing the incremental markings on each of the horizontal and vertical axes.
  • the disclosure includes a multi-focal eyeglass assembly having a frame that includes at least a first opening, and a lens dimensioned for receipt in the first opening.
  • the eyeglass assembly further includes a measurement system having multiple indicia on at least one of the frame and the lens that aid in taking measurements of the location of the eyes relative to the frame/lens when the frame is mounted on an associated user.
  • the indicia include a predetermined pattern provided on the lens.
  • the assembly includes a first image of the indicia when the frame is mounted on the associated user.
  • the image includes a photograph of the user wearing the eyeglass frame.
  • the indicia include markings on the lens where the markings include a horizontal axis and a vertical axis.
  • Incremental markings are provided along the horizontal and vertical axes, and the incremental markings may be equi-spaced.
  • the indicia include a second vertical axis offset and parallel to the first vertical axis.
  • a primary benefit of the disclosed method and platform is the ability to accurately measure an individual wearer for multifocal lenses.
  • Another advantage resides in allowing accurate measurements to be obtained online.
  • Another benefit is associated with allowing the customer to purchase properly fitting multifocal lens eyewear with ease and convenience.
  • Figure 1 is a pair of lenses marked for measurement and fitting of multifocal lenses.
  • Figure 2 is a pair of lenses marked for measurement and fitting of multifocal lenses.
  • Figure 3 is a pair of lenses marked for measurement and fitting of multifocal lenses.
  • Figure 4 is a close-up view of a single lens marked for measurement and fitting.
  • Figure 5 is a pair of lenses marked for measurement and fitting of multifocal lenses.
  • Figure 6 is a pair of lenses marked for measurement and fitting of multifocal lenses.
  • Figure 7 is a pair of lenses marked for measurement and fitting of multifocal lenses.
  • Figure 8 is a pair of lenses marked for measurement and fitting of multifocal lenses.
  • Figure 9 is a pair of lenses marked for measurement and fitting of multifocal lenses.
  • Fig. 10 is a pair of lenses marked for measurement and fitting of multifocal lenses.
  • the disclosure relates to a method and platform for obtaining measurement for fitting multifocal lenses to an individual wearer.
  • the subject matter of this disclosure is now described with reference to the following examples, and it is appreciated that there are many variations which may be developed as a result of the teaching provided herein.
  • Measurements to be obtained include (but are not limited to) pupil distance, segmentation height, potential pantoscopic tilt, and reading pupil distance.
  • Pupil distance measures the decentration needed for the wearer.
  • Segmentation height measures the height at which the distance and intermediate viewing zones will be located. The segment height is located just below the pupil to allow the wearer to use each zone without additional eyestrain.
  • Pantoscopic tilt aligns the reading zone on the lens with the wearer's optimal distance from the front of the eye. All measurements are preferably taken in millimeters, with the exception of pantoscopic tilt, which is measured in degrees, although other measurement values can be adopted as will become evident below. Measurements (except pantoscopic tilt) must be taken for the right and left eyes separately, as measurements may not be identical for both eyes.
  • the wearer will wear the eyeglass frames they have selected to purchase, in which measurement lenses, as shown in Figures 1-10, are placed.
  • the measurement lenses may also be marked with a circle, arc, or other denotation for measurement and alignment purposes.
  • the wearer may submit a photograph or image of his or her face, wearing the eyeglass frames in which the measurement lenses shown in Figures 1-10, are placed.
  • the photograph must be clear and preferably as level as possible and the face of the wearer should be at a distance such as three (3) to four (4) feet from the camera lens so that sufficient clarity and desired image resolution is obtained.
  • the photograph should preferably be taken in a well lit room, though backlighting is not as desirable and should be avoided (lighting from above, or directed towards the wearer's face is preferable).
  • the wearer should be looking into the camera. Photographs should also be taken of the wearer looking down as if reading a book. From these photographs, the necessary measurements can be determined via methods known in the art. Instructions relating to the desired set of images (e.g., both eyes, each eye), distances, etc. can be provided to the user/customer when the frame with the measurement lenses are provided, or it is contemplated that the instructions may be available online.
  • the wearer may choose to schedule an online fitting. Once an online fitting has been scheduled, the customer will receive a link which will lead to his or her one-on-one fitting. During the online fitting, the customer will virtually meet with a representative who will walk the customer through the fitting process. The representative will capture several images of the wearer, wearing the eyeglass frames selected for purchase in which the measurement lenses shown in Figures 1-10 are placed. Necessary measurements are determined from these images
  • the third method is a virtual based try-on system that allows the wearer to go online at which point an auto measure system aligns the detailed axis points to the wearer's eyeglasses. This system will then automatically report the needed information for fulfillment.
  • Method number four would be a remote fitting in which a wearer or optician can take a picture using a smart phone. That picture can be then be processed by either the automated system or the measuring system detailed in paragraphs 9, 10, and 1 1.
  • the custom fit multifocal lenses are shipped to the wearer, who may then insert the lenses into the purchased frames. While this subject matter has been disclosed with reference to the specific embodiment preferred by the inventor, it is apparent that other embodiments and variations can be devised by others skilled in the art without departing from the scope of the subject matter described herein. Any means by which a wearer can electronically transmit an image from which the above described measurements can be obtained is sufficient. Known software can calculate the distances and desired data by analyzing the image.
  • the software analysis can determine whether the image was taken from above or below the horizontal axis, or to the left or right of the vertical axis as a result of the known incremental spacing or indicia pattern on the lens/frame, and compare that value to the spacing on the image.
  • the user or customer may receive a specialized eyeglass frame used for measurement purposes (e.g., the specialized frame may include multiple indicia at predetermined locations on the frame that allow the above-described method of obtaining measurements to proceed in the same manner as providing multiple indicia on the lens).
  • the specialized frame may include multiple indicia at predetermined locations on the frame that allow the above-described method of obtaining measurements to proceed in the same manner as providing multiple indicia on the lens).
