The present pair of eye pieces may have a rotatable adjuster on the super structure of the eye pieces or on the headband between the eye pieces. When the rotatable adjuster is rotated one way, the headband decreases in effective length and tightens about the head of a user. When the rotatable adjuster is rotated the other way, the headband increases in effective length and loosens about the head of the user. With a rotatable adjuster, increases and decreases in length may be made in minute increments.

A frame for eyewear for protecting against ionizing radiation, comprising a frontal portion extending laterally by the two lateral protective elements, and a device for maintaining the frame on the face of a user under the conditions under which it is worn, and characterized in that the lateral protective elements are integrally formed with the frontal portion and in that the frontal portion and the lateral protective elements are made of a radio-attenuation material. Further, eyewear for protecting against ionizing radiation comprising such a frame and to an assembly comprising this eyewear and a device for distributing weight.

A protective goggle assembly having a pair of eye cup assemblies adapted to be easily adjusted by medical personnel. A cooperating ball and socket structure is provided within a housing structure extending from each eye cup assembly and which receive the nose bridge wire ends of a formed nose bridge wire. Each socket ball has a formed channel therethrough to receive the nose bridge wire ends and to provide adjustability. The ball and socket structure permit medical personnel to rotate the nose bridge during a medical procedure without effecting the position of the eye cups covering the patient's eyes.

An apparatus including a first surface configured to attach the apparatus to a second surface of another object, and a plurality of elongated nanofibers. Each nanofiber has one end connected to the first surface and an opposite end extending away from the first surface. The plurality of elongated nanofibers is configured to adhere to the second surface by nanoadhesion when brought into contact with the second surface.

A variable compression cushion for eyewear includes a lattice structure made up of lattice cells defined by lattice elements. The parameters of the lattice structure may be configured to create a desired compressibility in the cushion. Different zones of the cushion may have different compressibility. The variable compressibility enables the cushion to be configured to optimize the face pressure experienced by a user when the eyewear is worn to enhance the comfort of the user. Some embodiments of the cushion also include structures to improve ventilation through the cushion. Some embodiments of the cushion also include structures that channel moisture away from the portion of the cushion that contacts the face of the user to improve user comfort.

A frameless goggle with a lens that is structurally self-supporting without any external support from a frame, chassis, or other, similar components. The resulting goggle is more streamlined and has fewer parts to manufacture and assemble. In some embodiments, the goggle lens includes an integral support portion that improves the stiffness and strength of the lens.

The present disclosure discloses a goggle device and a spectacle frame thereof. The spectacle frame includes a buckling structure arranged on an end portion thereof. The buckling structure has an accommodating space and an entrance in spatial communication with the accommodating space. The buckling structure includes a cantilever arranged in the accommodating space and a retaining wall that is arranged in the accommodating space and is spaced apart from the cantilever. A free end portion of the cantilever is arranged adjacent to the entrance, and the cantilever is rotatable between a lock position and an unlock position. When the cantilever is at the lock position, the free end portion shields the entrance. When the cantilever is rotated to the unlock position by an external force, the free end portion does not shield the entrance, and the cantilever is deformed to store an elastic force.

A structure includes a goggles body including rim sections and temple sections, an imaging device arranged between the rim sections, light-emitting elements arranged on an outer edge of the rim sections, and an electricity supply element, a control module, a storage device, and a data transmission device arranged in the temple sections. A server host device is also included. The server host device includes a wireless transmission module, a recognition processing module, and a driving processing element. As such, a surgeon may wear the goggles body in a surgical operation to acquire supplemented lighting in the eyesight range and a function of recording the entire process of the surgical operation. The surgeon may take a motion of a predetermined hand gesture to issue a control instruction corresponding thereto in order to execute the control instruction on a medical device to allow the surgeon to control hardware necessary for the operation.

A goggle may include a goggle frame, a lens assembly magnetically coupled to the goggle frame, and first and second retention features securing the lens assembly to the goggle frame at first and second locations, respectively, to resist decoupling of the lens assembly from the goggle frame. The lens assembly may be removable from the goggle frame by actuating only one of the first retention feature or the second retention feature. A method of removing a lens assembly from a goggle frame may include actuating a first latch securing the lens assembly to the goggle frame; after actuating the first latch, pivoting the lens assembly away from the goggle frame about a second latch securing the lens assembly to the goggle frame; and after pivoting the lens assembly, laterally translating the lens assembly away from the second latch without actuating the second latch.

A frame for an eyewear comprises a lens opening and a groove surrounding the lens opening. The lens opening may be defined by an upper frame portion, a lower frame portion, a first lateral side portion, and a second lateral side portion of the frame. The groove may interchangeably receive and secure a first lens and a second lens within the lens opening. The first lens may have a different thickness than the second lens. The lens opening may extend across both eyes of the wearer.
