Sep 30, 2023 · What are polarized sunglasses and how do they work? Polarized sunglasses are eyewear with lenses that have a built-in optical filter to block horizontally polarized light. They work by selectively allowing vertically polarized light to pass through, reducing glare and improving visual clarity.
Ask students to explain how this “light” is polarized. Then ask students about the polarization of light and other electromagnetic waves. Then go through the four ways to polarize light: transmission, reflection, refraction and scattering. In this lesson, we focus on transmission and reflection.
Polarizing sunglasses cut road glare better in some positions than in others. When light reflects from water, asphalt, or other nonmetallic surfaces, it becomes polarized—that is, the reflected light is usually vibrating more in one direction than others.
