iPhone anti-glare case (or alternative ideas)

[Gone in 60]

Give it a try, Empty, but I've tried a shade. My last job made a unique product - a digital dash display for racing go karts using a cell phone. We thought a hood around the phone would be good for shading glare. However, since a motorcycle, like a go kart moves around relative to the sun, we found the hood pretty much useless. The guy looking at a hooded screen to fly a drone is in one position staring at the phone and doesn't move around relative to the sun.
