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.
Mar 14, 2023 · Polarized sunglasses are a specialized eyewear designed to reduce the brightness of reflected surfaces, such as water or snow. The lenses of polarized sunglasses are laminated with a film containing vertically aligned microscopic crystals that block and absorb light waves.
How do polarised sunglasses work? The magic of polarised lenses lies in their filter or special chemical coating. The filter is either inserted inbetween glass lenses or as a chemical coating applied to the lenses in a vertical pattern, which blocks horizontally polarised light while allowing vertical light waves to pass through.
