>Horses have incredible vision. They can almost see in 360 degrees. But that comes at a price. Their vison at that field is almost two-dimensional. So they can have an incredible field of vision, but it’s rather flat.
>Yes, horses can see all around, but they don’t have any depth perception. So a horse can see all around it, but when my horse saw that six inch ditch, her two-dimensional vison didn’t see a small little wash. She saw a chasm that she needed to leap across, because obviously it was a gaping crack in the earth and she couldn’t just trot across it.
