A laser protection eyewear lens includes a lens substrate comprising an embedded wavelength filter having a first filter function, and a multi-layer dielectric filter applied to at least one of an inside and an outside surface of the lens substrate that comprises a second filter function having at least one center wavelength and bandwidth. The first filter function of the embedded wavelength filter and the second filter function of the multilayer dielectric filter produce a combined filter function that attenuates light reflecting off the multi-layer dielectric filter.

Protective goggles for human use including a pair of protective goggles for human use with at least one lens, an upper edge that is positioned against the user's forehead and a lower edge that is positioned against the user's cheek. Each of the user's eyes are covered by a separate section of lens and each of these sections extends along at least one line of curvature. It is intended that each lens section has a first and a second line of curvature that, at least in substantial part, are positioned transversely to one another, and along which the individual sections of lens extend; furthermore, that the lines of curvature of one lens section are inclined towards the lines of curvature of the other lens section in terms of their positioning.

Face shields provide protection against harmful objects ranging from flying debris to bodily fluids. In the wake of the global pandemic caused by COVID-19, protective face coverings have become utilized by the general population to reduce infection. Presented herein is a novel protective face shield comprising several sections which may be articulated to operate in several positions including fully extended, fully retracted, raised, and lowered. In the fully extended position, the shield provides a level of protection for both the wearer and those around them. In the fully retracted position, the shield is raised and collapsed to conform to a typical visor.

The invention relates to a pair of goggles which comprise a frame with two rims in which an optical unit is respectively intended for being assembled via a reversible attachment device in order to provide an inner attachment of said optical unit in said rim, each device comprising a button and a cavity rigidly connected to an outer edge of the optical unit and the rim, respectively, said button being capable of being inserted into said cavity in order to provide external locking of the optical unit in the rim, each rim having one recess opening onto the rear, each optical unit having a front bearing surface which, in the assembled state, is arranged against a rear complementary bearing surface of said recess, at least one of the outer edges being reversibly deformable to allow the placement and the withdrawal of said button in said cavity when the bearing surfaces are arranged against one another.

Hearing protection and communication apparatus using vibration sensors are disclosed. An example wearable electronic device includes means for transducing vibrations associated with speech into a first signal; means for transducing sound associated with ambient noise into a second signal; and means for processing to cause a speaker to output a signal to reduce the ambient noise; detect an identifier in the speech; and cause audio data representative of the speech to be transmitted to a second device associated with the identifier.

A personal entertainment respiratory apparatus provides air to a user to provide a fully immersive entertainment experience. The personal entertainment system may comprise a flow generator for providing the flow of air. A personal spatial respiratory interface may be coupled to the flow generator. The personal spatial respiratory interface may comprise an outlet for the flow generator. The personal spatial respiratory interface may further be configured to direct the flow of air within an ambient breathing proximity of a user. The personal entertainment respiratory apparatus may further comprise a controller and a sensory particle dispenser. The controller and sensory particle dispenser may be configured to selectively activate release of a sensory particle from the dispenser into the directed flow of air in response to an entertainment triggering signal.

A vision-protecting filter lens, including a multilayer optical film and a neutral-density optical filter.

A goggle includes a frame, a lens disposed within the frame, and a continuous roll-off system coupled to at least one of the frame and the lens. The continuous roll-off system includes a first canister positioned at a first end of the goggle, a second canister positioned at an opposing second end of the goggle, and a continuous loop of film extending across the lens and configured to selectively cycle between the first canister and the second canister.

A protective eye cover system comprising a nonporous dome-shaped lens shaped to fit over a human eye cavity and encircle an associated eye. The system also comprises a flexible base ring coupled to the lens, the base ring exhibiting sufficient flexibility to permit close adherence to the eye cavity. An adhesive attached to the base ring promotes a seal of the coupled base ring and lens to surface skin of the eye cavity. The sealing of the coupled base ring and lens to surface skin of the eye cavity prevents liquids from contacting the eye and surrounding area and further protect eyelash extensions from at least one of liquids, steam and heat. The lens is configured with a depth such that an inner surface of the lens does not contact eyelashes and eyelash extensions of a wearer. An anti-fogging agent prevents obstruction of wearer view.
