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.
The useful glare-blocking properties of polarized sunglasses are well-known to just about anyone who goes outside. What isn't so well-known is how they reduc...

Apr 16, 2023 · Polarized sunglasses are designed specifically to reduce glare so that you can see clearly in situations where you might otherwise squint or be blinded by reflected light. Glare is caused when light hits a reflective horizontal surface, causing light beams to be scattered horizontally.
Mar 14, 2023 · A polarized lens is essentially a filter that blocks out light waves which vibrate in one particular direction, with horizontally aligned light waves being the most likely to cause glare. This is achieved by using vertically aligned tiny crystals sandwiched between two sheets of film.
