A visor is a type of headwear that features a brim or peak, designed to shield the eyes from sunlight. It typically consists of a band that fits around the head, with the front part extending outward to block light. Visors are commonly used in outdoor activities like sports, gardening, and beach outings. Visors can be made from various materials, including fabric, plastic, or straw, and are often adjustable for comfort. They are popular among athletes, especially in sports like golf and tennis, where visibility and sun protection are essential.
