Definition of visor

The origin of the word "visor" can be traced back to the 16th century, where it was originally used to describe a long and narrow wooden board that was attached to the front of a ship's helmsman's seat to shield him from the sun and rain. In the late 1700s, the term "visor" began to be used to describe a flap of metal or leather that was attached to the front of a riding hat or helmets to protect the rider's face from the sun and wind. It wasn't until the 19th century that the term "visor" started to be used to describe a separate accessory that could be attached to hats, caps, and helmets. This new type of visor was typically made of a lightweight material such as canvas or felt, and it served a similar function to the earlier visors --- to protect the wearer's face from the elements. In modern usage, the term "visor" is commonly used to describe a separate accessory that can be attached to a baseball cap or other similar hats to shade the wearer's eyes from the sun. This type of visor has become a popular fashion accessory in recent decades, and it is often made from a variety of materials, including polyester, nylon, and spandex. In conclusion, the term "visor" has its roots in naval engineering, where it was used to describe a protective shield for sailors more than 400 years ago. Over time, the term evolved to describe a variety of protective flaps and shields, ultimately leading to the popular accessory that is commonly worn today.
