Visiireitä

Visiireitä are a type of protective headgear primarily used in historical combat and some modern sports. Historically, visors were integrated into helmets, particularly during the medieval period, to shield the wearer's face from blows, projectiles, and other battlefield hazards. They could be solid plates of metal, often articulated to be lifted or lowered, or more elaborate constructions with openings for vision. The design and effectiveness of visors varied greatly depending on the era and the specific type of helmet they were part of.

In modern contexts, visors are often associated with sports like fencing, hockey, and American football, as well as with certain professions such as welding or construction. These modern visors are typically made of transparent materials like polycarbonate or acrylic, offering protection from impacts, debris, or specialized hazards without completely obstructing the wearer's view. The primary function remains consistent: to safeguard the face and eyes. The term "visiiri" itself is a loanword, reflecting the long history and global adaptation of this protective element.
