A sun visor is a panel located on the front of a vehicle's windshield, designed to block the sun's glare. Sun visors were first introduced in cars in the early 20th century, and their popularity has grown steadily since then. Today, almost all cars come equipped with sun visors for both the driver and passenger side.
Sun visors are typically made from a reflective material that helps to deflect the sun's rays away from your eyes. This can be especially helpful when driving in bright conditions, such as during sunrise or sunset. Many sun visors also have an adjustable arm that allows you to position the panel in just the right spot.
While they are not required by law, sun visors can be a valuable safety feature, helping you to stay focused on the road ahead. If you find yourself frequently driving in sunny conditions, consider investing in a good quality pair of sun visors for your car.
