Ever noticed how difficult it is to see your electronics through polarized sunglasses? Most electronics have a polarizing film that reduces the glare on the LCD Panel. This is great right up until the point that you are wearing polarized sunglasses. The polarization of the electronics and that of your sunglasses cancel each other out giving you a very dark image. PBO LightPro* Technology by ZEISS is a revolutionary lens that offers the benefits of polarized sunglasses while allowing a clear view of your electronic panels.
