Present invention teaches a light-blocking (shielding) structure, as well as a novel eye mask, that has a base with two light-shielding bodies, with additional area supports, to effectively blocks light from the gaps around the mask, pad or patches, by using flexible materials that can contour or conform to the shape of a human nose, thus creating a better darkness effect to enhance quality sleep experience.

Automatic shading goggles that can be combined with fixing members, which can fix the goggles to the face of a wearer by separating end parts of foldable temples having a control module, includes: a goggle frame having front light-shield lenses and side light-shielding lenses; a skirt member detachably coupled inside the goggle frame to be brought in contact with the face of a wearer; and temples rotatably connected to the left and right of the goggle frame, respectively, and having a control module for controlling operation of the front light-shielding lenses, wherein the temples includes hinge parts having the control module and rotatably coupled to the left and right of the skirt member and earpieces separably coupled to ends of the hinge parts to be held on ears.

A welding protector (1) has a curved eye protection shield (10) with an electrically switchable light filter. The welding protector further has a magnifying cover (20) for arrangement on an eye facing inner side of the eye protection shield. The magnifying cover is pre-shaped based on a curve that extends equidistant to the curve the eye protection shield is based on. Further, the magnifying cover has two optical lenses (27) which in combination only partially cover the eye protection shield.

Sensor assisted head mounted displays for welding are disclosed. Disclosed example head mounted devices include an optical sensor, an augmented reality controller, a graphics processing unit, and a semi-transparent display. The optical sensor collects an image of a weld environment. The augmented reality controller determines a simulated object to be presented in a field of view, a position in the field of view, and a perspective of the simulated object in the field of view. The graphics processing unit renders the simulated object based on the perspective to represent the simulated object being present in the field of view and in the weld environment. The display presents the rendered simulated object within the field of view based on the position. At least a portion of the weld environment is observable through the display and the lens when the display is presenting the rendered simulated object.

A real-time virtual reality welding system including a programmable processor-based subsystem, a spatial tracker operatively connected to the programmable processor-based subsystem, at least one mock welding tool capable of being spatially tracked by the spatial tracker, and at least one display device operatively connected to the programmable processor-based subsystem. The system is capable of simulating, in virtual reality space, a weld puddle having real-time molten metal fluidity and heat dissipation characteristics. The system is further capable of importing data into the virtual reality welding system and analyzing the data to characterize a student welder's progress and to provide training.

Eyewear is provided including a frame, and a camera connected with the frame, in which the camera is configured to be controlled by a remote controller. The camera may be configured to capture video and/or a photo. The eyewear may include data storage, and the camera may be connected to the data storage. A wrist watch may be configured to act both as a time piece and a controller of the camera. The eyewear may also include a heads up display and/or a video file player. The eyewear may also include an electro-active lens.

An embodiment includes an auto-darkening apparatus for supporting welding performed by a human welder. The auto-darkening apparatus includes a housing configured to be removably installed into a welding helmet. The auto-darkening apparatus also includes an ADF lens assembly configured to transition from an un-darkened state to a darkened state in response to light from an arc being formed between a welding electrode and a work piece during a welding process. The auto-darkening apparatus further includes a magnification assembly integrated with the ADF lens assembly within the housing. The magnification assembly is configured to provide magnification of light coming through the ADF lens assembly. The magnification is continuously user-adjustable from a defined lower level of magnification to a defined upper level of magnification.
