Visor

A visor is a protective shield that covers the eyes or face, or a brim-like extension on a hat or cap that shades the eyes from sunlight. In common usage, visors can be integral parts of helmets or standalone shields, and they may be clear, tinted, mirrored, or opaque depending on function.

Types and uses

Helmet visors are designed to protect the eyes and face from debris, wind, UV light, and impacts. They are common in motorcycle and cycling gear, motorsports, construction and firefighting helmets, and aviation equipment. Visors are typically made from impact-resistant plastics such as polycarbonate or acrylic, and they may be clear or tinted, with coatings for anti-scratch, anti-fog, or UV protection. Some visors are fixed, while others flip up or retract for convenient access.

Standalone safety visors are used as face shields in laboratories, healthcare, and industrial settings. These visors can attach to headgear or frame-mounted systems and are chosen for full-face protection or targeted shielding.

Automotive visors refer to sun visors inside vehicles, which can be retractable and may incorporate mirrors. They reduce glare and protect occupants’ eyes from sunlight.

Cap visors are the forward-curving brims found on baseball caps and many sun hats. They provide shade and help reduce glare in bright conditions.

Materials, care, and standards

Visors are commonly constructed from polycarbonate, acrylic, or laminated glass, with surface coatings to improve durability and visibility. Cleaning typically involves mild soap and water; avoid abrasive cleaners. Safety visors used in professional contexts often conform to standards such as ANSI Z87.1 or EN 166, which specify optical quality and impact resistance characteristics.

Summary

Visors serve eye and face protection across protective gear, sports, transportation, and everyday wear, balancing visibility, comfort, and safety.
