Abstract: A sun visor extension for a vehicle sun visor having a distal edge and a distal end thereof. The visor extension includes an elongated substantially flat sleeve formed of two generally rectangular panels attached together along each common side margin and open at each end of the sleeve. The sleeve has a width substantially wider than that of the sun visor and a length substantially no greater than that of the sun visor whereby the extension is adjustably slidable lengthwise on the sun visor and is laterally slidable to extend the distal edge of the sun visor downwardly when in use to increase eye shading for the driver or passenger of the vehicle. Mating two-part VELCRO along one side margin provides releasable attachment between the corresponding side margins of the panels to facilitate installation.
