Cut and pasted from my original post...
I started looking around at a few local autoparts stores for the headlight protection film some have used on their hand sets but came up with ZIP. Not one store even knew what I was talking about. So I then went to a motorcycle store thinking that they might have something to protect lights on off road bikes and came up with something that will work perfect. They're called backgrounds and they're used as the back ground for the numbers racers put on their bikes. They come in a pack of 3 12"X17" panels, you can get them in all kinds of colors, including clear, they're thick flexable self adheasive and they cost me $18 for the 3 sheets. The company that manufactures them is called N-Style and you can see the exact product at the following link.

I cut a piece of the film slightly larger then the lens, removed the lens from the handset ( DO THIS AT YOUR OWN RISK I TAKE NO RESPONSIBILITY IF YOUR HANDSET LEAKS AFTER DOING THIS ) I applied the film to the lens and used a fine wood file around the edges of the lens to cut the film and bevel the edges so it wouldn't peel so easily. I used a hobby knife to cut out the holes for the screws and then reinstalled the lens. It's been nearly a year since I put the stuff on and it's still there and working great.
