Why does the horizon always appear to be at eye level?
The horizon is eye level at the waters edge and at fifty feet above it.
Looking both ways down a long straight and level railway line, again the horizon is eye level.
It’s as if the rails have been laid down inside a bowl and I’m in the middle.

“Horizon line-is always at eye level. Picture yourself at the seashore and looking out at the ocean you notice that the water meets the sky at your eye level. This never changes. You may be in an airplane 1000 feet up and the level that the ocean meets the sky is still at your eye level! Or you may be lying down on the beach and the ocean level drops with you. Think of it as an invisible plane that cuts through everything, that always exists at eye level.
Hint: Your horizon line always falls at eye level regardless of where you’re looking. For instance, if you are looking down, your eye level remains at the height of your eyes, not down where you are looking.”

Low distance between you and the ground plus huge distance between you and the horizon equals horizon appearing always at eyelevel.
It is only at eye level when you’re looking at it.
Process of elimination: if you look at a point that’s below the level of your eyes, you’ll be looking at the ground below the horizon, and if you look at a point above it, you’ll be looking at the sky or something else that’s above the horizon.
The effect is a function of how one positions the head while making observations.
Does it always appear at eye level? I remember standing on the sea shore, and to me it always looks like the horizon is up a bit. If I feel like I’m looking up, can it still be at eye level? I think it might be just a matter of perception.
