Abstract

Features are disclosed relating to an article such as eyewear customized to individual wearer parameters (e.g., measurements, preferences, etc.), and to systems and methods for customizing eyewear to individual wearer parameters. The system includes an input for receiving data representative of a three dimensional configuration of a portion of a wearer's face and an input for receiving data representative of a desired position where the wearer would like an eyewear frame to reside on the wearer's face. One system also includes a processor for determining a change in configuration of an eyewear component blank to allow the eyewear frame to reside in the desired position, and an eyewear component modifier for modifying the eyewear component blank so that the frame will reside in the desired position.

First claim

What is claimed is:

1. A three dimensional orientationally corrected eyeglass comprising:
a frame;
at least one lens;
a left earstem;
a right earstem;
a permanently fixed nosepiece integrally formed on the frame, the nosepiece comprising a first nosepiece side, a second nosepiece side, and a nosepiece bilateral asymmetry configured to complement and not accentuate a bilateral asymmetry of a wearer's face to position the eyeglass in a preselected orientation with respect to the wearer's face;
a first distance from the first nosepiece side to a first tear duct on the wearer's face when the eyeglass is positioned in the preselected orientation; and
a second distance from the second nosepiece side to a second tear duct on the wearer's face when the eyeglass is positioned in the preselected orientation,
wherein a difference between the first distance and the second distance is less than a reference difference for a reference nosepiece that does not include the nosepiece bilateral asymmetry, the reference difference being a difference between a reference first distance from a first nosepiece side of the reference nose piece to the first tear duct and a reference second distance from a second nosepiece side of the reference nosepiece to the second tear duct.

2. The three dimensional orientationally corrected eyeglass as in claim 1 , wherein at least a portion of the eyeglass conforms to a surface of a wearer model representative of a three dimensional configuration of at least a portion of the wearer's head.

3. The three dimensional orientationally corrected eyeglass as in claim 2 ,
wherein the wearer model defines a calculated straight-ahead line of sight crossing the center of a pupil and extending in an anterior-posterior direction along a horizontal plane parallel to the wearer model's central transverse plane, and
wherein at least a portion of an eyeglass model representative of a three dimensional configuration of the eyeglass is deflected, with respect to a default configuration, when the eyeglass model is placed in an as-worn configuration on the wearer model such that the optical centerline of the lens is substantially parallel to the calculated straight ahead line of sight.

4. The three dimensional orientationally corrected eyeglass as in claim 2 , wherein the nosepiece has left and right dermal contact surfaces having a total dermal contact surface area, and
wherein at least 85% of the total dermal contact surface area conforms to the three dimensional configuration of a corresponding surface of a wearer's nose.

5. The three dimensional orientationally corrected eyeglass as in claim 4 , wherein at least 95% of the total dermal contact surface area conforms to the three dimensional configuration of the corresponding surface of the wearer's nose.

6. An eyeglass comprising:
a unitary frame defined by a single unit;
a first lens having a first optical centerline; and
a second lens having a second optical centerline,
wherein the first optical centerline and the second optical centerline form an angle of at least 2 degrees when the eyeglass is in an undeflected state,
wherein the unitary frame is adapted to support the first lens and the second lens in a wearer's field of view when in use, and
wherein the first optical centerline and the second optical centerline are parallel when the eyeglass is deflected to an as-worn orientation on the wearer.

7. The eyeglass as in claim 6 , wherein the first optical centerline and the second optical centerline form an angle of at least 15 degrees when the eyeglass is in an undeflected state.

8. The eyeglass as in claim 6 ,
wherein a wearer model corresponding to a three dimensional model of at least a portion of a wearer's head defines a calculated straight ahead line of sight which crosses a center of a pupil and extends in an anterior posterior direction along a horizontal plane parallel to the wearer model's central transverse plane, and
wherein the first optical centerline is substantially parallel to the calculated straight ahead line of sight when a three dimensional configuration of the eyeglass is positioned in an as-worn configuration on the wearer model.

9. The eyeglass as in claim 8 , wherein the angle formed by the first optical centerline and the second optical centerline is reduced by at least 50% in the as-worn configuration as compared to the undeflected state.

10. The eyeglass as in claim 8 , wherein the angle formed by the first optical centerline and the second optical centerline is reduced by at least 90% in the as-worn configuration as compared to the undeflected state.

11. An eyeglass comprising a frame and at least one lens having at least a first power, a second power, and an optical center line,
wherein a wearer model corresponding to a three dimensional model of at least a portion of a wearer's head defines at least a first line of sight corresponding to the first power and a second line of sight corresponding to the second power,
wherein the at least one lens is configured such that the first line of sight is aligned with a first portion of the lens corresponding to the first power and the second line of sight is aligned with a second portion of the lens corresponding to the second power when a three dimensional configuration of the eyeglass is positioned in an as-worn orientation on the wearer model,
wherein at least the first power or second power is determined based at least in part on an amount of frame deflection, with respect to a default configuration, when the three dimensional configuration of the eyeglass is positioned in an as-worn orientation on the wearer model, and
wherein at least one of the first line of sight and the second line of sight is parallel with the optical center line when the eyeglass is deflected to an as-worn orientation on the wearer model.

12. The eyeglass as in claim 11 , wherein the at least one lens comprises a progressive lens power transition corridor extending between the first portion and the second portion.
