Quoted: (picts in links are huge, so viewer beware)
HERE is a pict though my brand new 512.65 rev F eotech. I manually focused the camera kind of “though” the optics if you will and you can see the reticle is fine.
But when you FOCUS CLOSER you can see some kind of line. When looking at it with the naked eye the line seems translucent or invisible. Kind of like how the Predator looked in the movie, or maybe kind of like the seam in the glass off a large aquarium.
I hope my description hasn’t thrown you guys off, but I was wondering if this is the sign of a bad sight, or normal phenomenon.

I hate to disagree with Bobfried because he seems to know about photography, but he has it exactly backwards. It is apparent that you ARE focusing closer in the second photo as you stated- not further. Let me explain...
First, your reticle is WAY too bright. Turn it down some. Do you still see a "line"?
Second, I'm not sure exactly what you mean about the "line" although this explanation might help:
The hologram reticle is in focus at infinity even though it is recreated on the rear lens of the sight. This is the 3-dimensional nature of holography. The reticle remains in focus with the target. Your eye can stay focused on the target and the reticle stays in focus with the target at the same time. This allows the shooter to maintain focus on the threat, whereas with iron sights, your eye must focus back and forth between the target and the front sight post. This is one of the superior advantages the holographic sights have over all others. It also means that it is difficult to photograph the reticle because your camera lens must focus at infinity to get the reticle in sharp focus (like your first photo), but if you focus on the sight (like your second photo) then the reticle goes out of focus. This is also why some people say the reticle looks fuzzy when they hold the sight up in front of them, but when they take it outside and look at a distant target the reticle looks sharp. Make sense?
This photo illustrates what I am trying to say. You can clearly see the truck in the distance in sharp focus along with the reticle while the front sight post at the bottom of the image is out of focus. The human eye works exactly the same as a camera lens. (This is an actual photo taken through an EOTech and not a Photoshop cut and paste.) Again, in this photo his reticle is a little too bright which is causing the "glow" around the edges of the reticle. If you turn down the brightness you will get a much sharper reticle image.
