To be fair, sometimes the blinding is a piece of duct tape over the display on a piece of fancy OTS industrial equipment. Though we needed to poke at it occasionally, so we needed a duct tape flap we could lift up every now and then rather than just a bare piece. I forget if I made ours or if C made it, but I remember our little blinding flap fondly. (This is more common than you'd think.)
