Abstract
Abstract Disclosed is a hingeless eyeglass frame designed so the entire eyeglass frame provides a medially directed force at the posterior portion of the earstems to increase the retentive force between the eyewear and the head. In one vented embodiment, each lens of a dual-lens eyeglass is provided with a plurality of apertures extending therethrough, at the junction between the lens and the surrounding frame. The unitary frame or conventionally hinged frames may also have apertures to allow airflow for ventilation.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
178 words
A hingeless eyeglass frame for receiving a separate lens, comprising: an arcuate lens support section for extending across the front of the face of a wearer to support at least one lens in the wearer's line of sight, said support section having a central zone and first and second lateral zones, said support section further having a recess in the frame for receiving at least one lens; and first and second earstems extending from the first and second lateral zones such that when the frame is on the front of the wearer's head the first and second earstems extend posteriorly from the lens support section, past the wearer's ears, and towards each other partway around the back of the wearer's head, said first and second earstems terminating in first and second posterior ends; each of said earstems concave in a medial direction and having a separation between the first and second posterior ends within the range of about 2 inches to about 4 inches in an unstressed orientation: wherein the eyeglass frame is of a hingeless unitary construction.
Claim 2
Dependent Claim
178 words
A hingeless eyeglass frame for receiving a separate lens, comprising: an arcuate lens support section for extending across the front of the face of a wearer to support at least one lens in the wearer's line of sight, said support section having a central zone and first and second lateral zones, said support section further having a recess in the frame for receiving at least one lens; and first and second earstems extending from the first and second lateral zones such that when the frame is on the front of the wearer's head the first and second earstems extend posteriorly from the lens support section, past the wearer's ears, and towards each other partway around the back of the wearer's head, said first and second earstems terminating in first and second posterior ends; each of said earstems concave in a medial direction and having a separation between the first and second posterior ends within the range of about 2 inches to about 4 inches in an unstressed orientation: wherein the eyeglass frame is of a hingeless unitary construction.
Claim 3
Dependent Claim
45 words
A hingeless eyeglass frame as in claim 1, wherein the first and second earstems are separated laterally from each other by at least about 5.2 inches in the relaxed, unworn configuration, at at least one point between the posterior ends and the lens support section.
Claim 4
Dependent Claim
47 words
A hingeless eyeglass frame as in claim 2, wherein the first and second ends are moveable in a lateral direction throughout a lateral range of motion to a separation distance of at least about 4.00", while maintaining a medially directed bias throughout said lateral range of motion.
Claim 5
Dependent Claim
38 words
A hingeless eyeglass frame as in claim 3, wherein the curvature of the eyeglass frame throughout said arcuate lens support section remains substantially unchanged while said first and second ends are advanced throughout said lateral range of motion.
Claim 6
Dependent Claim
30 words
The frame of claim 2, in which the distance between the ends of the earstems can be increased by up to 100% beyond the distance corresponding to the relaxed unworn
Claim 7
Dependent Claim
40 words
The frame of claim 2, in which the linear dimension from the front of the frame at its center to the midpoint between the posterior ends of the earstems is within the range from about 6 to about 7.5 inches.
Claim 8
Dependent Claim
14 words
A hingeless eyeglass frame as in claim 1, comprising an integrally molded polymeric material.
Claim 9
Dependent Claim
21 words
A hingeless eyeglass frame as in claim 1, further comprising first and second lens orbitals on said arcuate lens support section.
Claim 10
Dependent Claim
50 words
The frame of claim 1, in which the frame includes, on both sides of the central zone first and second relative minimums in the radial thickness of the frame, said minimums having a smaller dimension than at least one radial thickness in each of the first and second lateral zones.
Claim 11
Dependent Claim
18 words
The frame of claim 9, in which the relative minimums are located near respective ends of the recess.
Claim 12
Dependent Claim
34 words
The frame of claim 9, in which the radial thickness minimums are located within the range of from about 35 degrees to about 75 degrees away from the wearer's straight ahead line of sight.
Claim 13
Dependent Claim
30 words
The frame of claim 11, in which the radial thickness minimums are located between about 40 degrees and about 65 degrees away from the wearer's straight ahead line of sight.
Claim 14
Dependent Claim
103 words
The frame of claim 1, in which the vertical thickness of the frame in the central zone is within the range from about 0.1 to about 0.5 inches; the anterior to posterior thickness of the frame in the central zone is within the range from about 0.1 to about 0.4 inches; and the vertical thickness of the frame is greater than about 0.4 inches at relative minimums in the radial thickness of the frame, the radial thickness of the frame at the relative minimums being less than about 90% of the radial thickness of the frame at the midpoint of the central zone.
Claim 15
Dependent Claim
42 words
The frame of claim 13, wherein the thickness of the frame in the vertical direction at about 90 degrees away from the wearer's line of sight along the arc of the frame is in the range from about 0.375 to 0.41 inches.
Claim 16
Dependent Claim
30 words
The frame of claim 1, further comprising a lateral ridge extending laterally from the top of the frame for increasing the relative strength of the frame in the horizontal plane.
Claim 17
Dependent Claim
52 words
The frame of claim 1, in which the maximum interior separation between the earstems is in the range of from about 5.2 to about 5.75 inches, so that frame can be comfortably advanced around the neck of the wearer and retained there without applying any material compressive pressure to the wearer's neck.
