The one on the left is a locked brummel on one end and a regular brummel on the other. I made it before knowing that the tail on the second eye can be braided to form a locked brummel.
The middle one is made like the one on the right except a short section on cover is first added to the eye, Brion Toss calls it a dutchman's hat. There is a cover tail on each side of the eye that you can whip to the outside or they can be taped, tied down with thread, or woven into the locked brummel, and then the other cover put over it. It's best to use a thin cover for the eyes because it has to pass through the rope for the second locked brummel.
