Abstract: The present invention relates to a sun visor extension which is removably mountable to a rearview mirror. The sun visor extension includes a housing and a pair of arms being slideably extendible from an opening in the housing. In the extended position, the arms extend between visors of the vehicle to provide blocking or shading of sun and glare though the windshield or above the rearview mirror. The arms can be formed of plastic or polarized plastic. A mounting member is attached to the housing for mounting the housing to a portion of the rearview mirror. For example, the mounting means can be a first portion of hook and loop material attached to the housing and a second portion of hook and loop material attached to the rearview mirror.
