| 20140268058 | SYSTEM AND METHOD FOR REMOTELY SUPPLYING PRESCRIPTION EYEGLASSES - Disclosed, in one general aspect, is a sample eyeglass frame that includes a frame having a shape designed for everyday use. The frame includes a left temple having an left earpiece on one end and a left lens interface portion on the other, a right temple having a right earpiece on one end and a right lens interface portion on the other, and a bridge having left and right sides. A left lens interfaces with the left lens interface portion of the left temple and the left side of the bridge, and has a left set of optical measurement markings spanning at least part of the left lens. A right lens interfaces with the right lens interface portion of the right temple and the right side of the bridge, and has a right set of optical measurement markings spanning at least part of the right lens. | 09-18-2014 |
| 20150359423 | TRIAL FRAME AND METHOD FOR MEASURING KEY PARAMETER THEREOF - A trial frame includes a trial frame body and at least one measurement subject having a visual invariant geometric characteristic. The trial frame body has at least one key parameter. The measurement subject is disposed on the trial frame body and collaborates with a measurement method. A two-dimensional image of the measurement subject is recorded by an image capturing device when the trial frame body fits to a user, and the key parameter is deduced from the two-dimensional image of the measurement subject. | 12-17-2015 |

| 20120113393 | Device and process for progressive addition lens design - A progressive addition lens design device for designing progressive addition lenses to permit a patient to experience a variety of distance vision fields and reading vision fields. The device includes a frame adapted to hold in place in front of each of a patient's eyes three lens mounts, each lens mounts being adapted for adjustment in rotation and side-to-side translation. A third lens displaying the patient's base prescription mounted in one of the lens. A first and second lens is mounted in the other two lens mounts. The first and second lenses, each have a transition zone and a power ramp zone and they have complementary surfaces so that when stacked together they create a standard progressive addition lens with a distance vision field, a reading vision field and transition region. When the first and second lenses are moved relative to each other the locations of the distance vision field, the reading vision field and the transition region are adjusted allowing the patient to experience a variety of distance vision fields, reading vision fields, and transition regions | 05-10-2012 |

| 20110242489 | Apparatus for Determining Prescription for Reading Lenses for Eyes with Mild AMD - An apparatus is provided for finding and defining a prescription for reading glasses for an AMD patient whose Macula and Fovea are damaged enough that the patient has double vision, i.e. the patient sees two images of every object within the field of view of the Macula and Fovea. The apparatus positions reading lenses in various locations in front of the patient's eyes until the patient indicates that he/she now sees one image for each object in the field of view of the Macula and Fovea. The X-Y coordinates of the location of each lens axis in relation to the patient's visual axis are offset dimensions indicated for each eye by the apparatus and is thus the prescription for reading lenses. | 10-06-2011 |
| 351230000 | With individual lens holder | 2 |
| 20100134762 | ADJUSTABLE EYEGLASS FRAME - An eyeglass frame includes left and right length adjustable temples; left and right viewing assemblies adjustably mounted in left and right frames respectively; and a length adjustable bridge. Either viewing assembly includes a transversely moveable frame element slidably secured to the left or right frame; a longitudinally moveable frame element slidably secured to the transversely moveable frame element; a front aperture member slidable about the longitudinally moveable frame element and including an upper longitudinal slot and a cut on an inner side; a corresponding rear aperture member slidable about the longitudinally moveable frame element and including a lower longitudinal slot and a cut on an inner side; and a circular member rotatably secured to the longitudinally moveable frame element and including two projections moveably disposed in the slots respectively. An aperture is formed by at least the cuts, whereby rotating the circular member will change size of the aperture. | 06-03-2010 |
| 20140268059 | TRIAL FRAME - A trial frame is provided in which a trial lens can be moved close to, or moved away from the front of the patient's face, and includes: a main bar, one end of which is connected to a hinge, and another end is turnable forward and backward relative to a patient's face; a slide member that is slidably mounted on the main bar; a sub-bar that is provided at the lower part of the slide member to be at a right angle to the main bar; a support shaft and a support plate that are slidably hung from the sub-bar; a vertical shaft that is provided on the support plate; an angle-adjusting member, one end of which is supported by the support plate to rotate around the vertical shaft; and trial lenses, each of which is hung by a fork-shaped arm at the lower part of the angle-adjusting member. | 09-18-2014 |
