20090038169 | APPARATUS FOR MEASURING THICKNESS OF LENS - An apparatus for measuring a thickness of a lens includes a plurality of first touch heads, a base, a plurality of second touch heads and a driving mechanism. The first touch heads each has a first curved contact surface for coming into contact with a first surface of the lens. The first curved contact surfaces have different curvatures for being selectively mated with the first surface of the lens. The base is configured for selectively mounting one of the first touch heads thereon. The second touch heads each has a second curved contact surface for coming into contact with a second surface of the lens. The second curved contact surfaces have different curvatures for being selectively mated with the second surface of the lens. The driving mechanism is configured for driving the mounted second touch head to move relative to the mounted first touch head. | 02-12-2009 |
20100077627 | LENS SHAPE MEASURING METHOD AND LENS SHAPE MEASURING APPARATUS - A lens shape measuring method includes: bringing a feeler into contact with an outer peripheral surface of a spectacle lens, the outer peripheral surface corresponding to a lens shape of spectacles, the feeler being rotatable about a rotation axis and movable forward and backward relative to the rotation axis in a radial direction, and, while keeping the contact state, moving the feeler along a contact surface of the feeler with the lens shape in a circumferential direction, to measure radii ρi (i=0,1,2, . . . n) of the lens shape over an entire circumference of thereof, the radii ρi representing change in distance from a geometric center of the lens shape to the feeler, a measurement region of the lens shape being divided into multiple sub-regions, and within each of the sub-regions, the rotation axis line being moved to a position to cause the feeler to measure the lens shape within the sub-region. | 04-01-2010 |

20110113639 | HOLDING MECHANISM FOR USE WITH AN OPHTHALMIC TRACER, AND METHOD - The present invention relates to an ophthalmic holding mechanism for holding an eyeglass frame. The holding mechanism includes a base, a clamping mechanism configured for releaseably securing a lens mount of an eyeglass frame, and an actuator operatively associated with the clamping mechanism for causing linear and rotational movement thereof. The clamping mechanism is moveably coupled to the base for linear and rotational movement about an axis of rotation relative to the base, wherein the clamping mechanism is rotatable about first and second spaced pivot points. The present invention also relates to a method of tracing a lens mount of an eyeglass frame. | 05-19-2011 |

20120240420 | DIGITAL LENS GAUGE - A handheld digital lens clock device is disclosed for measuring front and back dioptric power of eyeglass lenses based on curvature and refractive index. The device includes a reference probe, a measuring probe for measuring a sagittal depth of a lens relative to the reference probe and a digital display to show the measurement information. The device can further include a refractive index input button that allows the device to measure the optical power of lens composed of materials having different refractive indices. The device can further include a calibration button that is used to set a reference or zero reading by placing the reference probes and measuring probe on a flat surface. A tube level can also be included on the device to assist orienting the device when taking measurements. | 09-27-2012 |
