Is the sun visor in front of the car useful?

[Robinson]

Front sun visors are useful. A car sun visor is a panel installed above the driver to prevent glare from sunlight. It can be flipped down when in use and flipped up when not needed. The materials used include plastic, EPP, PU foam, cardboard, etc., and they can be categorized into front, side, and rear visors. Here are the specific details: 1. Function: Under intense sunlight, the sun visor can lower the temperature of the dashboard and steering wheel, preventing the driver from burning their hands on a hot steering wheel. Additionally, most car dashboards are made of plastic, and prolonged exposure to high temperatures can produce unpleasant odors and toxic substances. Data shows that the sun visor has the greatest effect on the dashboard area, avoiding direct sunlight exposure and preventing interior aging. 2. Front sun visor: There aren’t many varieties, generally including aluminum foil and non-woven fabric types. Aluminum foil visors usually come in two forms: plain "smooth" type and patterned type, with standard dimensions of 60*130cm, suitable for most compact cars. In hot weather, the aluminum foil can be placed outward to reflect sunlight. When purchasing a sun visor, it’s best to choose one with suction cups and avoid "smooth" types or overly cheap front visors, as they may easily fall off.
