Hey there little one! A visor is like a hat, but without the top part. It only covers your forehead and the front of your face. It has a brim or a bill that sticks out in front of your eyes to protect them from the sun. It's like a little roof over your eyes. Visors can be made of different materials like plastic, foam, or fabric. They can be worn for sports like tennis or golf, or just for fun on a sunny day. So, if you ever need to keep the sun out of your eyes, wear a visor!
