Abstract: A visor extension device for attaching to a sun visor to provide additional screening of bright light beyond a perimeter of the sun visor includes a plate being mountable to the sun visor. A sleeve is slidably mounted to the plate. The sleeve is downwardly extended from the plate to provide additional blocking of light below the sun visor. The sleeve has a slot extending through the sleeve and through opposing ends of the sleeve. Each of the opposing ends of the sleeve slidably receives one of a plurality of extension plates. The extension plates are selectively extendable from the associated one of the opposing ends to block light to the sides of the sun visor.
