A visor (26) for a helmet (22) comprises: an air delivery element (34) for delivering air to a surface of the visor (26). The air delivery element (34) comprises: at least one inlet (28) for receiving air from an air source (30); and a plurality of outlets (44) through which air is transportable to the surface of the visor (26). The visor (26) may also include a ridge (84) formed adjacent to the plurality of outlets (44) for creating a Coanda effect in air passing through the plurality of outlets (44).

Described herein is a self-cleaning visor (1) comprising: a support structure (2) having a see-through portion (2a); an endless transparent film (3); a film drive means (4); and at least one film cleaning means (5); and two fasteners (6). The support structure (2) is releasably attachable to an associated helmet (10) by the two fasteners (6) such that it is tiltable between a raised see-through position (A) and a lowered see-over position (B). The support structure (2) encloses the endless transparent film (3) except for at the see-through portion (2a). The support structure (2) comprises the film drive means (4) and the at least one film cleaning means (5). The support structure (2) supports the endless transparent film (3) to selectively be driven by the film drive means (4) in a continuous loop over the see-through portion (2a) and past the at least one film cleaning means (5).

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.
