The invention discloses a free-form surface goggles-based see-through helmet mounted display device. A pair of free-form surface goggles is arranged in front of a helmet body, wherein micro-display imaging devices and relay lens assemblies are arranged in front of the helmet body and on the two sides of the upper part of the free-form surface goggles respectively; the two relay lens assemblies are arranged at an inclination angle of 42 degrees; each relay lens assembly comprises a first relay lens, a second relay lens, a third relay lens, a fourth relay lens, a fifth relay lens and a sixth relay lens; and the first relay lens, the second relay lens, the third relay lens, the fourth relay lens, the fifth relay lens and the sixth relay lens are arranged in turn. In the device, a tire tread-shaped free-form surface is used for imaging, so the device can realize a large off-axis angle of 33 degrees, correct the aberration well and obviously improve the imaging quality and has a simple structure; the device is suitable to be arranged on a human head and conforms to the characteristic of man-machine efficacy; and by using the design of a short-focus large angle of view, the device has an exit pupil of between 12 and 15mm and an angle of view of between 40 and 50 degrees.

A flat or curved photochromic laminate structure and a plastic photochromic lens blank can be produced in a simple and efficient manner from relatively low-cost polymeric sheet materials. These laminates can be used to provide goggles, face shields, windows, window coverings, skylights, and optical lenses having efficient, uniform and high quality photochromic properties. The use of a polyesterurethane as the binder for the photochromic material has been found to improve the performance of the photochromic material. There may be a desire to have a protective exterior layer (e.g., an abrasion resistant layer) in combination with the lens system, but that may be provided in various methods. In the case of using the laminate in a goggle application, the laminate may be hard coated on one or both outer surfaces with an abrasion resistant coating, antireflective coating, and/or an anti-fog hard coating.

A light for headgear includes a shroud plate having a shell configured to receive a goggle mount, the shell having a periphery generally conforming to a contour of the headgear; and a lighting system on the shell having at least one light. The light further includes a power unit electrically coupled to the lighting system.

Eye shield device adapted for fog prevention for use in a ski goggle, dive mask, medical or testing face shield or the like, while preventing undesirable hot spots on the eye shield, comprising an optically-transparent substrate, a plurality of conductive regions defined on the substrate and connected to a powered circuit of one or more channels. The regions on the substrate are electrically isolated from each other in a first embodiment, and the regions on the substrate are not electrically isolated, or contiguous with adjacent regions on the substrate, in a second embodiment. The regions may be uniformly-sized or of varying sizes and shapes from one region to the next region, and resistivity per square of heating material applied to the regions may be selected based on formulation of the heating material and/or thickness of the heating material.

An anti-glare protection device, for example a pair of welding goggles, a welding mask or a welding helmet, includes a supporting part with a sight opening (3), an optical filter element arranged in the sight opening, and a protective plate (1), which is mounted or can be mounted on the supporting part such covering the optical filter element. For the protection of the filter element against contamination with dirt and in order to protect the wearer of the anti-glare protection device against undesirable gases, smoke and dirt, a seal (4) made out of an elastically compressible material is disposed either between the supporting part and the protective plate (1) or between the filter element and the protective plate (1). The seal extends substantially around the sight opening and is advantageously affixed either to the supporting part, to the protective plate (1), or to the filter element.

Swimming goggles comprise a left frame body, a right frame body, lenses, a connecting element, each of the left and right frame bodies having an outer peripheral face, and the outer peripheral faces forming a combination base having a first platform and a second platform thereon, the first platform forming a combination element; the connecting element interconnecting the left and right frame bodies and forming a surface side and a nasal side, the nasal side forming a first junction and a second junction with respect to the first platform and the second platform, respectively, the first junction forming a clamping hole corresponding to the combination element, the nasal side being conformed to the contour of the combination bases, wherein the nasal side and the combination bases together form a smooth surface which could be perfectly fit into both sides of the nose bridge for comfortably wearing in swimming.

This invention relates to a means of securing a lens member into a snow goggle frame member, wherein the goggle frame member includes first insertion apertures, with first locating blocks at front edge, the lens member has a lens secured thereon, the lens includes first troughs to receive a corresponding first block therein, a pair of first rails are formed at respective sides of the first trough, each first rail has a first notch which includes a pair of second notches thereat, retainers are secured to the goggle frame and lens frame respectively, one end of the first insertion aperture includes a first insertion post at one end and a first insertion section at the other end thereof to receive the first insertion post therein, the first insertion section is then inserted into the first notch. The goggle may be replaced with various lenses and secured firmly.

The invention relates to the technical field of electric air supply air filters, electric welding variable-light goggles, and controller devices of the electric air supply air filters and the electric welding variable-light goggles, in particular relates to an electric air supply air filter, electric welding variable-light goggles, and a controller of the electric air supply air filter and the electric welding variable-light goggles. Compared with the prior art, the controller is in signal connection with the electric air supply air filter and the electric welding variable-light goggles in a wireless, wired or wireless and wired combined manner to control the electric air supply air filter to work; meanwhile, information of air flow rate and electric quantity can be seen from a screen of the electric welding variable-light goggles; the content of oxygen in air can be detected by a low oxygen sensor, when the content of the oxygen is lower than a threshold value, a low-oxygen alarm warning tone can be generated, and meanwhile, an 'O2!' icon of a display screen of the controller flashes to generate a low-oxygen warning signal to be sent; the air flow rate and the electric quantity can be seen from the electric welding variable-light goggles, so that the working state of the electric air supply air filter can be learned by a user in real time without picking an electric air supply breather from the waist; and therefore, the work efficiency can be greatly improved.

A laser protection device that can stay tightly on an animal by going over its head and eyes using a flexible material such as nylon. The device has polymer or glass windows that are designed to block or attenuate the treatment light in order to protect the eyes of the animal from laser damage. As an integral feature, the windows are partially transparent in the visible spectrum to allow the animal to see its surroundings.
