> well you can move your eyes to expand your vertical field of view just as easily. Not true, our eyes are optimized for horizontal scanning. We have specialized extraocular muscles for doing this, and as a result horizontal eye scanning relatively is fast, accurate and easy compared to vertical scanning. This has less to do with our eyes being side-by-side (which is a product of our biological symmetry) and more to do with the horizontal world we live in.
