## Abstract

Provided herein are examples of headworn supports, such as eyewear, configured to provide passive venting by providing pathways between a lens and a frame and/or by providing a smooth anterior profile to allow a laminar flow of air on an anterior surface of the lens. The pathways through the frame and lens of the eyewear can be configured such that they do not provide a direct path to the eye of a wearer. The headworn supports provided herein can provide venting while reducing or preventing unwanted light, particles, or other debris from contacting the eye of the user. The headworn supports can also be configured to exhibit excellent ballistic performance.

## Claims

### Claim 1

A headworn support comprising:
a lens having a posterior surface adjacent to a face of a wearer when worn and an anterior surface opposite the posterior surface;
a frame comprising a plurality of contact points configured to contact the lens; and
a retention assembly attached to the frame, the retention assembly configured to secure the lens to the frame so that the lens contacts the frame at the plurality of contact points,
wherein, when the lens is secured in the headworn support, an upper edge of the lens and a lower edge of the frame are spaced apart between contact points to allow venting of the lens and a total, continuous chord length of the upper edge of the lens that is spaced apart from the frame is at least 20% of the total chord length of the upper edge of the lens,
wherein a posterior surface of the frame between contact points extends a protrusion distance beyond a posterior extension of the posterior surface of the lens, wherein the protrusion distance is less than or equal to about 4 mm.

### Claim 2 (depends on 1)

The headworn support of claim 1, wherein one or more of the plurality of contact points comprises an attachment point configured to structurally support the lens when the lens is secured in the headworn support.

### Claim 3 (depends on 1)

The headworn support of claim 1, wherein the total, continuous chord length of the upper edge of the lens that is spaced apart from the frame is at least 50% of the total chord length of the upper edge of the lens.

### Claim 4 (depends on 3)

The headworn support of claim 3, wherein the total, continuous chord length of the upper edge of the lens that is spaced apart from the frame is less than or equal to 80% of the total chord length of the upper edge of the lens.

### Claim 5 (depends on 1)

The headworn support of claim 1, wherein the protrusion distance is equal to 0.

### Claim 6 (depends on 1)

The headworn support of claim 1, wherein the protrusion distance is less than or equal to 3.2 times a center thickness of the lens.

### Claim 7 (depends on 1)

The headworn support of claim 1, wherein, when worn, there is no direct path from an eye of the wearer between the upper edge of the lens and the lower edge of the frame.

### Claim 8 (depends on 1)

The headworn support of claim 1, wherein the posterior extension does not intersect the frame over at least half of the total chord length of the upper edge of the lens.

### Claim 9 (depends on 1)

The headworn support of claim 1, wherein, when worn, a viewing angle from an eye of the wearer to an edge of the frame is greater than or equal to about 48 degrees.

### Claim 10 (depends on 1)

The headworn support of claim 1, wherein a venting angle is greater than 0 degrees above the horizon.

### Claim 11 (depends on 1)

The headworn support of claim 1, wherein a venting angle formed by an anterior surface of the frame and the upper edge of the lens is greater than or equal to 0 so that gaps between the upper edge of the lens and the lower edge of the frame between contact points define optically blind vents that are not visible when the headworn support is viewed straight on.

### Claim 12 (depends on 1)

The headworn support of claim 1, wherein a lower edge of the lens does not contact the frame.

### Claim 13 (depends on 1)

The headworn support of claim 1, wherein the lens is configured to be secured in a goggle in addition to the headworn support, the goggle comprising:
a lens support adapted to support the lens in the wearer's field of view, the lens support having a channel configured to receive the lens and secure the lens in place; and
a padded layer attached to an anterior surface of the lens support, the padded layer configured to be pressed against the head of the wearer when in use.

### Claim 14 (depends on 1)

The headworn support of claim 1, wherein the headworn support is an eyeglass comprising at least one earstem attached to the frame.

### Claim 15

A headworn support comprising:
a lens;
a frame comprising one or more contact points configured to contact the lens, the frame configured to position the lens in a line of sight of a wearer;
a retention assembly attached to the frame, the retention assembly configured to secure the lens to the frame so that the lens contacts the frame at the one or more contact points,
wherein, when the lens is secured in the headworn support, an upper edge of the lens and a lower edge of the frame are spaced apart between contact points to allow venting of the lens,
wherein a venting angle formed by an anterior surface of the frame and the upper edge of the lens is greater than or equal to 0 so that gaps between the upper edge of the lens and the lower edge of the frame between contact points are not visible when the headworn support is viewed straight on, and
wherein the gaps formed between the upper edge of the lens and the lower edge of the frame define an empty space.

### Claim 16 (depends on 15)

The headworn support of claim 15, wherein the headworn support is an eyeglass comprising an earstem hingedly attached to the frame, wherein the retention assembly is attached to the frame and the earstem.

### Claim 17 (depends on 16)

The headworn support of claim 16, wherein the retention assembly comprises a door configured to be actuatable independent of the earstem when the earstem is folded behind the frame.

### Claim 18 (depends on 15)

The headworn support of claim 15, further comprising at least two attachment points configured to attach to opposite, lateral edges of the lens.

### Claim 19 (depends on 15)

The headworn support of claim 15, further comprising an attachment point at a midpoint of the frame.

### Claim 20 (depends on 15)

The headworn support of claim 15, further comprising an attachment point comprising an opening formed between two side walls formed by the frame.

### Claim 21 (depends on 15)

The headworn support of claim 15, wherein a posterior surface of the frame between contact points extends a protrusion distance beyond a posterior extension of a posterior surface of the lens, wherein the protrusion distance is less than or equal to about 4 mm.
