Eyepoint is another name for 'eye relief' that is the distance from the viewfinder that you can see the entire viewfinder.
It's normally defined as a given distance for a given lens, thus you may have a distance of 20mm with a 50mm lens and 16mm with a 17mm lens and so on.
The term "High Eyepoint" was coined by Nikon to describe their original longer than standard eye relief.
A little exercise
Focus on infinity with a standard lens of around 50mm and then move back from the eyepiece about 400mm and note what you see. Then move in progressively until you can see everything in the viewfinder. This should help those who have difficulty with the concept of eyepoint.
so is it like if I change to a bigger eyepiece I get a better eye relief?
