Disclosed is a method for determining a parameter of an optical equipment including an optical lens including permanent markings and being mounted in a spectacle frame, including: positioning the optical equipment is before a pattern in a first position; positioning a portable electronic device including an image acquisition module in a second position so as to acquire an image showing together the pattern seen through at least part of the optical lenses of the optical equipment in the first position and at least part of the spectacle frame of the optical equipment in the first position; detecting the permanent marking on the optical lens using the image acquired by the image acquisition module of the portable electronic device in the second position; and determining at least one parameter of the optical equipment based on the position of the permanent marking.

A method of measuring lens shape of a spectacle lens, the method comprising: a) providing a spectacle lens on a surface; b) providing an image recording apparatus comprising a camera and a display; c) positioning the image recording apparatus so that the camera is largely parallel to the surface; d) capturing an image of the spectacle lens, the captured image comprising a total surface area of a camera-facing side of the spectacle lens; e) indicating positions of features of the spectacle lens in the captured image; and f) measuring a shape of the spectacle lens and determining image coordinates of the spectacle lens features.

A computer implemented method and system for fitting eyeglasses captures images of the consumer while naturally trying-on frames in the normal course of selecting new frames. The system and method capture natural images of frame placement and using gaze prediction and eye tracking techniques ascertain eye measurements for accurate placement of the prescription within new eyewear.

Techniques are described for applying an edge sealant to the edge of a multi-layer optical device. In particular, embodiments provide an apparatus that performs a precision measurement of the perimeter of an eyepiece, applying the edge sealant (e.g., polymer) based on the precision-measured perimeter, and subsequently cures the edge sealant, using ultraviolet (UV) light that is directed at the edge sealant. The curing process may be performed within a short time following the application of the edge sealant, to ensure that any wicking of the edge sealant between the layers of the eyepiece is controlled to be no greater than a particular depth tolerance. In some examples, the edge sealant is applied to the optical device prevent, or at least reduce, the leakage of light from the optical device, and also to ensure and maintain the structure of the multi-layer optical device.

Eyewear can include lenses having perimeters that are customized for an intended wearer. The perimeter of the lenses can be determined based on anatomical features of the wearer's face, field of vision, or other parameters specific to that individual. A provisional lens perimeter obtained may be modified in curvature and/or size to arrive at a desired final lens perimeter, based for example on stylistic preferences or to accommodate external elements affecting the perimeter and/or curvature of the lens. Customized lenses can be fabricated based on the determined lens perimeters. The customized lenses can be assembled into completed eyewear that is customized for a wearer, for example having shapes, sizes, and designs not otherwise possible.

Disclosed is an eyewear including: a frame headwear configured to be worn by a user, the frame headwear including a front part, and at least one lens holder, each lens holder being configured to be removably fastened to the frame headwear in a predetermined mounted position and each lens holder including an associated pair of ophthalmic lenses attached to the lens holder, each lens of the associated pair of ophthalmic lenses being configured to be movable relative to the lens holder while being attached to the lens holder.

Systems and methods are disclosed for generating a 3D computer model of an eyewear product, using a computer system, the method including obtaining an inventory comprising a plurality of product frames; scanning a user's anatomy; extracting measurements of the user's anatomy; obtaining a first model of a contour and/or surface of the user's anatomy, based on the extracted measurements of the user's anatomy; identifying, based on the contour and/or the surface of the user's anatomy, a first product frame among the plurality of product frames; determining adjustments to the first product frame based on the contour and/or the surface of the user's anatomy; generating a second model rendering comprising the adjusted first product frame matching the contours and/or the surface of the user's anatomy.

A method for generating modified eyeglass frame manufacturing data including the following steps: a. providing a plurality of eyeglass frames; b. selecting one frame among the plurality of eyeglass frames; c. determining data relative to the selected frame; d. modifying the determined data whilst respecting at least one predetermined conception rule, so as to obtain modified data; and e. computing the modified data obtained by the modification so as to generate modified eyeglass frame manufacturing data.

Sensor data is captured with a sensor. The sensor data includes a lens-position of a prescription lens relative to a reference point of an optical coherence tomography (OCT) system. A mirror of a reference arm of the OCT system is positioned at an optical pathlength between an eye region of the prescription lens based at least in part on the sensor data. An OCT signal is generated while the mirror is positioned at the optical pathlength. At least one depth profile is generated that includes the prescription lens and the eye region.

A lensmeter system may include a mobile device having a camera. The camera may capture a first image of a pattern through a lens that is separate from the camera, while the lens is in contact with a pattern. The mobile device may determine the size of the lens based on the first image and known features of the pattern. The camera may capture a second image of the pattern, while the lens is at an intermediate location between the camera and the pattern. The second image may be transformed to an ideal coordinate system, and processed determine a distortion of the pattern attributable to the lens. The mobile device may measure characteristics of the lens based on the distortion. Characteristics of the lens may include a spherical power, a cylinder power, and/or an astigmatism angle.
