Abstract
Described herein are methods and systems for customizing and personalizing eyewear. The methods and system consider optimal parameters for each wearer's personal visual situation and configures frames around them.
Claims20
A computer-implemented method for constructing custom eyewear, comprising:
- receiving wearer information related to anatomy and lifestyle of a wearer of the custom eyewear;
- calculating, based at least in part on the anatomy and lifestyle of the wearer, values for lens parameters, wherein the lens parameters set a lens position that is optimized for the wearer, wherein the lens parameters comprise at least one of lens offset (x & z), pantascopic angle (PA), corneal vertex distance (CVD), lens face form angle (LFFA), minimal eye point height (EPH), minimal B-size, minimal distance to upper, or minimum corridor length;
- obtaining a scanned image showing morphology of an anatomical part of the wearer;
- selecting a frame from a digital catalog;
- and
- modifying the frame to accommodate the values for the lens parameters and the scanned image, wherein modifying the frame comprises modifying values for one or more frame parameters to accommodate the lens parameters, thereby building the frame and constructing custom eyewear having the lens parameters, wherein the one or more frame parameters comprise one or more of a frame model ID, OMA data, HBox, VBox, incline, frame face form angle (FFFA), parametric model, color options, frame material, groove type, or bevel type.

A computing device comprising:
- a memory;
- and
- a processor coupled to the memory, the processor being configured to cause the computing device to:
- receive wearer information related to anatomy and lifestyle of a wearer of a custom eyewear;
- calculate, based at least in part on the anatomy and lifestyle of the wearer, values for lens parameters, wherein the lens parameters set a lens position that is optimized for the wearer, wherein the lens parameters comprise at least one of lens offset (x & z), pantascopic angle (PA), corneal vertex distance (CVD), lens face form angle (LFFA), minimal eye point height (EPH), minimal B-size, minimal distance to upper, or minimum corridor length;
- obtain a scanned image showing morphology of an anatomical part of the wearer;
- select a frame from a digital catalog;
- and
- modify the frame to accommodate the values for the lens parameters and the scanned image, wherein modifying the frame comprises modifying values for one or more frame parameters to accommodate the lens parameters, thereby building the frame and constructing custom eyewear having the lens parameters, wherein the one or more frame parameters comprise one or more of a frame model ID, OMA data, HBox, VBox, incline, frame face form angle (FFFA), parametric model, color options, frame material, groove type, or bevel type.
6 more elements
A non-transitory computer-readable medium comprising computer-executable instructions, which, when executed by a processor, cause the processor to perform a method comprising:
- receiving wearer information related to anatomy and lifestyle of a wearer of a custom eyewear;
- calculating, based at least in part on the anatomy and lifestyle of the wearer, values for lens parameters, wherein the lens parameters set a lens position that is optimized for the wearer, wherein the lens parameters comprise at least one of lens offset (x & z), pantascopic angle (PA), corneal vertex distance (CVD), lens face form angle (LFFA), minimal eye point height (EPH), minimal B-size, minimal distance to upper, or minimum corridor length;
- obtaining a scanned image showing morphology of an anatomical part of the wearer;
- selecting a frame from a digital catalog;
- and
- modifying the frame to accommodate the values for the lens parameters and the scanned image, wherein modifying the frame comprises modifying values for one or more frame parameters to accommodate the lens parameters, thereby building the frame and constructing custom eyewear having the lens parameters, wherein the one or more frame parameters comprise one or more of a frame model ID, OMA data, HBox, VBox, incline, frame face form angle (FFFA), parametric model, color options, frame material, groove type, or bevel type.
