What is a Polarized Car Sun Visor Extension?

Glare Guard’s car visor extender protects your eyes, no matter what conditions there may be. Use our car sun visor as an extra pair of polarized sunglasses to reduce the harmful glare affecting your driving.

What makes Glare Guard’s Car Sun Visors work better than other visors?

Our gray sun visor extender is made of the highest quality polarized film and is hand cut and inspected to ensure customer satisfaction. All visors have a strong bracket on a ratchet system so you can adjust the visor into the best spot for you. Whether you are shorter or taller, you can adjust the visor to ensure maximum effectiveness.


It is the only USA-Made polarized visor in the world. We manufacture both the polarized film, and the visors in the USA (under Wave Polarizer, LLC).
