Glass Display Shield -- Ah, the great outdoors. Unfortunately Glass does not share your enthusiasm. Glass usually remains vivid and visible outdoors, but on days lauded by the opening lines of the Sesame Street theme, your display will be chased away faster than the clouds. Display Shield helps Glass shine on the sunniest days and also shields your own privacy since anyone can see your Glass screen from the front. This is especially useful when trying to record video from inside your 501st Legion Stormtrooper armor. I found that the light bounces off the inside of the helmet and reflects back into the lens. Ain’t nobody got time for that.
