It's caused by the stress from the lens material itself or the different index of refraction from the hard coat on the lenses and the anti-reflective coating itself. Birfringence doesn't impact the performance of the anti-reflective coating though. Unless they really mess it up _-KAZ-_ • 1 min. ago jesus 7
