Eliminate Scratches with Invisible Shield

I came across this interesting product called Invisible Shield. This is a strong, film like product that prevents scratches on gadgets and electronic devices, plus an array of other equipment.

It was first used in the military to protect helicopter blades, so it must be pretty tough. It's uses now include protecting scratches on iPods, computer screens, watches, cameras, cell phones and any other device/screen you want protected.

It seems easy to apply. Peel off the invisible shield from the backing and then spray the film with shield spray and apply to your device. The instructions say you can remove this shield if you desire and it also comes with a lifetime warranty. For more detailed instructions, click here

This invisibleSHIELD video on YouTube shows the strength of this product.

What do you think? I wonder if it protects eyeglass lenses? Between those and my watch, I'm always scratching them.
