A visual field observation training lens is disclosed, along with corresponding training eyewear. An associated method for training visual observation toward a designated field of view is provided.

Provided are a face shield that can easily be combined and used with various masks and a mask-equipped face shield.

A face shield 1-1 is the face shield 1-1 that is attachable/detachable to/from a mask 2, and covers at least an eye of a face of a user who wears the mask 2. The face shield 1-1 is made of a film 101-1 having flexibility and translucency. At least a pair of cut lines 102L and 102R through which straps 202 of the mask 2 can be inserted are formed in both left and right parts of the face shield 1-1. The cut lines 102 have engagement parts 102a and 102b to be engaged with the straps 202 inserted through the cut lines 102.

A goggle includes a frame, a lens, and a roll-off system. The frame has a first lateral end and an opposing second lateral end. The frame defines a lens cavity. The lens is disposed within the lens cavity of the frame. The roll-off system includes a first canister, a second canister, and an actuator mechanism. The first canister is at least partially integrally formed with the first lateral end of the frame. The first canister defines a first interior cavity configured to store a roll of film. The second canister is at least partially integrally formed with the opposing second lateral end of the frame. The second canister defines a second interior cavity configured to receive a strip of film from the roll of film. The actuator mechanism is configured to facilitate selectively dispensing the strip of film from the first canister across the lens to the second canister.

A tinting system for goggles for use when riding a dirt bike incorporating a combination of clear transparent layers of material and tinted layers of material upon the front surface of the goggles that are adapted to be torn off one at a time in a fast and efficient way to rid the goggles of dirt and grime and to adjust the amount of tint the goggles provide for any given lighting condition.

An eye treatment device includes the following: a goggle frame, having at least one cavity, configured to surround and be spaced from an eye; a corrective lens along a face of the goggle frame; and an inlet formed in an upper portion of the goggle frame, the inlet fluidly communicating the cavity to an external environment; further including: a sealing material along a perimeter of the goggle frame for forming a hermetical seal against skin around a socket of the eye, wherein the sealing material is a portion of a suction cup; and further including a tapered stopper for fluidly sealing the inlet, wherein the corrective lens is made from gas permeable material.

A method, equation, system, and device for electrically heating Indium Tin Oxide (ITO) and other transparent conductive materials having a uniform sheet resistivity for defogging and de-icing in a cold environment. The use of nonparallel busbars for connecting the conductive materials reduces excessive and dangerous hot zones. The mathematical analysis and equations provide a means of precisely providing an intermittent electrical connection so that the Watt density and heating is uniform, allowing much higher temperature for de-icing and defogging and more efficient use of energy. This same concept can be used for three dimensional formed heaters to compensate for non uniform sheet resistivity. Also shown are a means of improved busbar designs and an equation and a means of altering sheet resistivity to produce electric heaters with non parallel busbars of various shapes for uniform heating

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.

Goggles and eyewear with various features may be described herein. Such goggles and eyewear may include lenses that allow for the installation of larger roll-off films, adjustable nose sections to increase comfort of a wearer, sweat management systems that include a permeable gasket and a gutter, lens attachment systems, and co-molded frames of multiple different materials.

A goggle lens suitable for golfers to wear all-weather and a method of manufacturing the same are provided. The goggle lens comprises: a substrate, by weight, comprising: 1000 parts of resin, 0.038998 parts of yellow pigment, 0.041715 parts of green pigment, 0.014272 parts of blue pigment, 0.024569 parts of purple pigment, 0.0021 parts of orange pigment, and 0.010859 parts each of 580 nm light absorber and 490 nm light absorber; a high-reflection layer arranged on one surface of the substrate that is adapted to be away from eyes of the golfer; an anti-reflection layer arranged on another surface of the substrate that is adapted to be adjacent to the eyes of the golfer; two hardened layers arranged between the high-reflection layer and the substrate, and between the anti-reflection layer and the substrate; and one photocatalytic antibacterial layer; wherein a light transmittance of the goggle lens is between 27% and 29%.

There is provided a welding helmet (1) comprising a face protection member (3) moveable between a lowered position in which the face protection member (3) covers a wearer's face, and an upraised position, in which the face protection member (3) uncovers the wearer's face, a headband suspension system (9) for fixing the face protection member (3) to a wearer's head, a protective cap (17) comprising a flexible outer layer (19) and at least one compressible inner liner (21).
