The sunglasses are 'Polarized'. Try this: While looking at the computer screen with them on, turn your head 90 degrees. The screen should either go totally black or get clear! This is especially true on cell phones. The cell phone screens are polarized too. When you look through polarized lens they actually have tiny small lines imbedded into them. (this is how the help eliminate the sun blinding you) So when you put two devices together with Polarized lenses, they cancel each other out when at right angles!
