What does visor mean?
A visor is a projecting front piece of a cap that helps shade the wearer's face and eyes. The word can also refer to a rigid or transparent eye shield, such as the movable face covering of a motorcycle or welding helmet, and to a light, brimmed sun visor worn outdoors. In technical contexts, a visor may be a hinged cover over an opening in a vehicle, machine, or instrument. Although the modern cap sense is probably the most familiar, visor originally belonged to the vocabulary of armor and referred to the protective face opening of a helmet. The word's appearance in everyday language therefore ranges from clothing and sports to safety equipment and machinery. It is also occasionally used as a rare verb meaning to cover or protect with a visor.

Where does visor come from?
Visor entered Middle English from Anglo-French visiere and Medieval Latin visiera, forms ultimately connected with Latin visus, meaning “seen,” and visare, “to look at.” Its early historical sense concerned the sight-opening or protective front of a helmet; the cap and sun-visor senses developed later. The ultimate Latin root also underlies English cognates including visible, visual, vision, and visit.
