Therefore, the lens is not only easy to be buckled to the first buckle and the second buckle, but also easy to be detached for changing the lens.

A visor system for a protective sport helmet wearable on a head of a user is provided. The visor system comprises a visor for protecting at least part of a face of the user. The visor is transparent and comprises left and right connectors. The visor system also comprises left and right visor supports for supporting the visor on left and right sides of the protective sport helmet. The left and right connectors of the visor are toollessly connectable to and toollessly disconnectable from the left and right visor supports to allow the user to toollessly connect the visor to the left and right visor supports and toollessly disconnect the visor from the left and right visor supports. The visor system may be configured to define an open gap from a top edge of the visor to the outer shell.

Active dichoptic perceptual-learning tasks or dichoptic game play have been shown to significantly improve visual acuity of amblyopic children and adults. However, these dichoptic perceptual learning tasks are intensive and repetitive such that non-compliance is high. In contrast, the invention provides dichoptic perceptual learning in a manner that the user maintains its use and compliance is increased. Further, compliance becomes automatic if the user performs tasks in a normal manner and “forgets” that they are actually under-going treatment as it is integrated with minimal disruption to their life and activities. Accordingly, a methodology exploiting complementary dichoptic stimulation is presented.

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.

Roll-off film systems and methods are provided in accordance with one or more embodiments that may be installed on goggle frames or adaptors to goggle frames to provide improved field of vision for users. In particular, film canisters of the roll-off film systems may include a blade section configured to seamlessly contact the goggle frame or the adaptor to the goggle frame. Further, the blade section is configured remove mud or dirt from a used section of clear film when the used section is conveyed into the film canister to prevent excess mud or dirt from entering the film canister. The blade section also is configured to slant away from the lens of the goggle to allow the mud or dirt to fall away from the field of view on the lens to provide better field of view for the user.

A Goggle is provided which enables an improvement in skiing skills and techniques. A goggle 1 of the present invention comprises a lens body 11, a lens body supporting part 12 configured to support the lens body 11, a face plate part 13 positioned on a peripheral edge part behind the lens body supporting part 12, having flexibility and capable of coming into contact with a face of a wearer, and a gaze correcting part 14 provided in a center of the face plate part, having a rectangular column shape and enabling correction of a gaze of the wearer, the gaze correcting part 14 having mutually different colors on a facing surface 14a facing the wearer, a right side surface 14b located to the right of the facing surface 14a and a left side surface 14c located to the left of the facing surface 14a and dividing a field of view of the wearer into a right field of view and a left field of view.

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.

A glasses frame structure includes a chassis, a pair of temples, a pair of hinges, and a plurality of fasteners. The chassis has a pair of front rims and a pair of side rims respectivey next to the front rims. Each of the side rims of the chassis can receive a first side lens. Each temple has a rimmed portion adjacent to one of the side rims of the chassis. The rimmed portion of each of the temples can receive a second side lens. The hinges can pivotally connect the temples to the chassis. Some of the fasteners can fix the hinges and the first side lenses to the chassis, while some of the fasteners can fix the hinges and the second side lenses to the temples. With the glass frame structure, the side lenses can be installed more easily and firmly.

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.
