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. ## Claims ### Claim 1 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. ### Claim 2 (depends on 1) The system of claim 1, comprising a plurality of differentially sized standard eyewear frames. ### Claim 3 (depends on 1) The system of claim 1, wherein the gridlines are bounded by a visible perimeter box. ### Claim 4 (depends on 1) The system of claim 1, wherein separate intersecting gridlines are provided for each of the user's pupils. ### Claim 5 (depends on 1) The system of claim 1, wherein the grid has an overall shape selected from the group consisting of squares, rectangles, circles, and polygons. ### Claim 6 (depends on 1) The system of claim 1, wherein the horizontal axis provides one of either pupillary or interpupillary distance. ### Claim 7 (depends on 1) The system of claim 1, wherein the vertical axis provides the segment height. ### Claim 8 (depends on 1) The system of claim 1, wherein the coordinate points provide a direct measurement of both pupillary distance and segment height. ### Claim 9 (depends on 1) The system of claim 1, wherein the coordinate points on the gridline are arbitrary and the measurement of both pupillary distance and segment height are provided by a separate lookup table. ### Claim 10 (depends on 1) The system of claim 1, wherein the grids are etched into the lenses. ### Claim 11 (depends on 1) The system of claim 1, wherein the grids are attached to the lenses by a transparent removable film. ### Claim 12 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. ### Claim 13 (depends on 12) The method of claim 12, further comprising marking the position of the user's pupils on the lenses. ### Claim 14 (depends on 12) The method of claim 12, wherein the measurer is positioned at a distance of between 15 to 20 inches from the user. ### Claim 15 (depends on 12) The method of claim 12, further comprising looking up the coordinate in a separate lookup table. ### Claim 16 (depends on 12) The method of claim 12, further comprising repeating the measurement at least twice for each pupil. ### Claim 17 (depends on 12) The method of claim 12, wherein the gridlines are bounded by a visible perimeter box. ### Claim 18 (depends on 12) The method of claim 12, wherein separate interconnecting gridlines are provided for each of the user's pupils. ### Claim 19 (depends on 12) The method of claim 12, wherein the horizontal axis provides one of either pupillary or interpupillary distance. ### Claim 20 (depends on 12) The method of claim 12, wherein the vertical axis provides the segment height.
