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.
Apr 16, 2023 · Polarized sunglasses are eyewear made with special lenses that reduce reflected glare from surfaces such as water, snow, and glass. Polarized sunglasses can be especially useful in situations where you need to see clearly and avoid hazards.
Apr 6, 2020 · While they do elevate contrast that will enhance situations where glare can be distracting or dangerous, they don't offer any additional protection from harmful UV rays. However, polarized, tinted sunglasses’ glare reducing properties can alleviate the onset of sunlight-induced eye strain and headaches.
