The locking element has a locked and an unlocked position, and when the locking element is in the locked position the clamping ring is in the closed position.

Improved wearable optics is disclosed. The wearable optics comprises a frame member and a lens. The wearable optics also includes circuitry within the frame member for enhancing the use of the wearable optics. A system and method in accordance with the present invention is directed to a variety of ways to enhance the use of eyeglasses. They are: (1) media focals, that is, utilizing the wearable optics for its intended purpose and enhancing that use by using imaging techniques to improve the vision of the user; (2) telecommunications enhancements that allow the eyeglasses to be integrated with telecommunication devices such as cell phones or the like; and (3) entertainment enhancements that allow the wearable optics to be integrated with devices such as MP3 players, radios, or the like.

A facial shield for a protective headgear system includes a polymeric sheet having an upper portion configured to be coupled to a support and a lower portion having a lower extremity, wherein the upper portion includes a first hole, a second hole, and a third hole, each one of the first, second, and third holes laterally spaced from the other two of the first, second, and third holes, and the first hole including a first section having a first hole gap and a second section laterally adjacent the first section and having a second hole gap, wherein the first hole gap of the first hole is greater than or equal to the maximum vertical dimension of a first hook of the support, and wherein the second hole gap of the first hole is greater than a vertical base thickness of a base of the first hook and is less than the maximum vertical dimension of the first hook.

The present disclosure provides generally for a particle guard system and apparatus. The system may comprise temples, shield, and nose bridge. A particle guard may prevent or limit aspiration from entering the user's external environment via shield that covers the nose and mouth. The particle guard may comprise interchangeable components for personalization and various utility. The temples and the nose bridge may be available in various colors and styles for customization of the particle guard. The particle guard may possess attachments for various utility. Temples may comprise integrated attachments. For example, temples may contain a wireless signal device for external communication. The particle guard may comprise a sanitation system. Where the system includes external covering, shield may interface with the external covering via opening in the external covering.

A system for the treatment of the dry eye syndrome that is based on a light source. The system includes a disposable tip, to treat an eyelid. A corneal shield is used to protect the patient's eye.

An eye protector includes a lens configured to protect the wearer from projectiles, and an optically clear stack attached to the lens. The stack can have one or more removable layers. The eye protector also includes an optically clear dry mount adhesive layer attaching the stack to the lens. The dry mount adhesive may be self-wetting to attach the stack to the lens so that air between the stack and the lens can be removed after the stack is attached and/or adhered to the lens, for example, by applying pressure across the surface of the stack. The refractive indices of the lens, the dry mount adhesive, and each removable layer are matched to within about 0.2.

A brim shade has a shade element, a clip, and a hinge that joins the shade element and the clip to make the brim shade. The shade element and the hinge combine to create a shade that does not allow the light to get past the brim shade. The brim shade can be adjusted through 360 degree rotation and along the side of a hat to provide protection to the wearer.

A face shield assembly comprises a holder adapted to be worn on the body of a wearer. The holder has a support portion and a separate attachment portion connected to the support portion. The support portion of the holder defines an opening through which the wearer's neck is received or, in another embodiment, on the head of the wearer. In addition, a shield is removably connected to the attachment portion of the holder, the shield being formed of a transparent material. The shield further has a curved configuration around a generally vertical axis as well as being narrower at one end than the other.
