I use a Vello glass screen protector on my D800 and D810. Optically clear, and offers that little bit of protection against scratches from camera straps and other things in the camera bag. It makes sense - $25 to replace it if it gets scratched, but the cost to replace a camera's LCD is $50 or so for the part, and at least $100 for the labor - but if you send it to Nikon, it will cost more, because they go over the entire camera. Economics dictate that the screen protector is a wise choice.
I use the Vello glass screen on my 7D. I wear glasses and shoot with my left eye. I avoid lcd scratches that way
