How could there be a horizon on a flat earth?

I'm building a world that happens to be flat. Well, it has hills and mountains, but no curvature.

However, I still want to limit the eyesight to a few kilometers even if there are no hills around. I don't really care if towers/mountains allow you to watch further (though it would be a nice bonus). Basically, I want the world to be like ours at first glance.

A few informations on my world:

• People are mostly humanoid, no height difference.
• The setting is medieval, no pollution.
• The world was designed by gods who can do any magic they want, though they want to minimize their impact.
• Preferably, an eyeglass should allow you to see further.
• I would like to avoid (if possible) biological alterations/curse.
• Luminiferous aether is totally a thing in my world, no physics after the Michelson"“Morley experiment can be considered to be valid.
• There are no time zones (flat earth remember).
• I don't care what happens on the borders of the world, it is approximately the area of Europe and most of what happens will be on the center.
• Only the visible spectrum matters to this question.

So here are my questions:

• What effects could explain a horizon?
• What funny things would happen then?
• Isn't the Aether theory cool?
