To avoid being blinded when driving in bright weather when the sun shines directly into your windshield, you can lower your visors. But for a more effective and permanent solution, you can stick a strip on your windshield. The vinyl strip measures 60x6 inches and has an adhesive backing. The film is designed for outdoor sticking and has a lifespan of 6 years. You can choose a black or white opaque strip when ordering.
