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.
Expect students to look through the sunglasses and a polaroid film and figure out that the film must be oriented horizontally because sunglasses are vertically polarized. By doing this, they learn that polarized sunglasses change the light intensity.
Whether the light is transmitted, reflected, scattered or refracted, when its vibrations are aligned into one or more planes of direction, the light is said to be polarized. Polarization can occur either naturally or artificially.
