Abstract
Systems, methods and devices for measuring eyewear characteristics are provided. The eyewear measurement systems and devices comprise a plurality of measurement standard frames, each having lenses marked with visible gridlines specifically configured to the measurement standard frame to allow for the direct measurement of a PD and SH/FH with respect to each eye of the wearer.
Claims20
An eyewear measurement system comprising
- at least one measurement standard eyewear frame having one or more lenses;
- wherein the one or more lenses have a grid having vertical and horizontal axes disposed thereon comprised of a plurality of visible intersecting gridlines, each intersection defining a coordinate point, and, the lenses and gridlines configured to overlay a portion of a wearer's field of view when worn by the wearer;
- and
- wherein the vertical and horizontal axes are separately labeled and configured to be indicative of at least pupillary distance and segment height such that each coordinate point on the grid provides a simultaneous measurement of both pupillary distance and segment height of a user's pupil in a single measurement.
1 more element
A method of measuring the position of a user's pupil comprising:
- providing a measurement standard eyewear frame having one or more lenses, wherein the one or more lenses have a set of visible intersecting gridlines having vertical and horizontal axes, each intersection defining a coordinate point, and wherein the vertical and horizontal axes are separately labeled and configured to be indicative of at least pupillary distance and segment height such that each coordinate point on the grid provides a simultaneous measurement of both pupillary distance and segment height of a user's pupil in a single measurement;
- positioning the measurement standard eyewear frame on the user's face such that the gridlines overlay atop the user's pupils;
- determining a coordinate point of the gridlines centered on each of the user's pupils;
- and
- obtaining the pupillary distance and segment height of each of the user's pupils from the determined coordinates.
