Carbide 240 Air - side panel window clarity

Hi, can any owners of this case comment on the side panel window clarity?

I got this case for Christmas and the window appears slightly blurry in places. I have removed the protective covering and ensured the panel is clean. Just trying to figure out if this is normal or if my panel is faulty!

I have the Corsair 100i cooler fitted and you cannot clearly read the corsair badge on the cpu block through the window. It appears out of focus.
