Query: Smaller Viewing Area

Got this in Hong Kong when purchasing a lot of little add-ons for my Canon 5D Mark II. It cuts down the viewing area through the viewfinder so I don't like it at all. I have a protective cover for the live view so not worried about smudges. Interesting - I noticed I wasn't enjoying taking photos as much anymore. Then remembered I had that eyepiece on there. Really affected the view area.
