SharkEye's tough case shutters your iPhone's screen

SharkEye has a unique take on rugged-case protection for your iPhone. The screen protector is retractable.

SharkEye's Rugged iPhone 4 Case costs $49.99.

We've seen some interesting iPhone cases in our time, but SharkEye's rugged iPhone cases add a really interesting twist with its built-in retractable screen protectors.

When you're using the phone, the screen protector lives tucked away in the back of the case. But when you want your screen to be covered, you just pull down the shade, so to speak, and slide the cover over the screen (the video below is worth a thousand words).

SharkEye makes cases for the black iPhone 4 (sorry, the case isn't compatible with the white version at this time), as well as the iPhone 3 and 3GS, and you have a choice of several accent colors from which to choose.

SharkEye cases cost $49.99, which is what Otterbox's popular Defender Series goes for.
