I just compared my Nikon FE2 and FG with an OM1. and they all fade a little in the corners of the viewfinder with my glasses on*. I've gotten used to it apparently. But if it bothers you then definitely go for a high eyepoint viewfinder. If a set of Nikon glass is more than you want to invest, you may want to look at the Minolta SRTs, which have high eyepoint viewfinders, are built like bricks, and can be really cheap.
